New details on man killed by snake at childcare centre

<p>A childcare centre in Queensland, where father-of-three suffered a <a href="https://www.oversixty.com.au/health/caring/dad-dies-after-being-bitten-by-deadly-snake-in-child-care-centre" target="_blank" rel="noopener">fatal snake bite</a>, is under investigation by workplace safety officials. </p> <p>Jerromy Brookes, 47, was bitten multiple times on his arm while attempting to remove a snake from the premises on Tuesday afternoon. He was not a qualified snake catcher, and tragically passed away in Townsville Hospital after going into cardiac arrest at his home in Deeragun. </p> <p>“Workplace Health and Safety Queensland (WHSQ) is investigating an incident that occurred at a business in Townsville,” a spokesperson told 7News. </p> <p>“As this is a current investigation, WHSQ is not able to provide further information at this time.”</p> <p>WHSQ has the power to prosecute allegations of workplace safety breaches. </p> <p>Brooke is survived by his wife and three children. </p> <p>His wife was the person who called emergency services and provided first aid when Brookes began showing symptoms at home. </p> <p>A family friend has paid tribute to the fallen father saying: “Jerromy was helping remove a snake from another childcare centre in Townsville when the incident occurred." </p> <p>“He was doing his very best to keep the children safe.”</p> <p>It was believed that Brookes was trying to remove an eastern brown snake, one of the deadliest in the world, however the species has not been officially confirmed. </p> <p>Police are reportedly not investigating the incident as a criminal matter, but are working to provide a report for the coroner. </p> <p><em>Images: Facebook</em></p>

Dad dies after being bitten by deadly snake in child care centre

<p>A beloved father has passed away after reportedly trying to remove an eastern brown snake from a child care centre in North Queensland. </p> <p>Jeremy Brookes attended the child care centre on Tuesday afternoon after one of his relatives reportedly called him over to remove the snake, according to <em>The Courier Mail</em>. </p> <p>Brookes was not a qualified snake handler and was bitten multiple times on his hand and arm.</p> <p>According to Queensland Ambulance Service acting district director Paula Marten, Brookes then managed to drive to his Deeragun home but he soon went into cardiac arrest.</p> <p>HIs wife performed CPR until paramedics arrived and he was rushed to hospital, but unfortunately could not be saved. </p> <p>“(He) was found to be in cardiac arrest by our crews,” Marten said. </p> <p>“The call was made by the patient’s wife, who then commenced CPR as the patient went into cardiac arrest.</p> <p>“The information provided to us was that the gentleman had been bitten in a different location and attended back to his residence, where his wife has immobilised his arm and wrapped it, when the onset of the symptoms occurred.”</p> <p>She added that snake bites were common in North Queensland and they were rarely fatal, but advised that if "you’re not aware of snakes, treat them as if they are venomous."</p> <p>“It’s really important that you stay calm and keep the person calm.</p> <p>“Apply basic first aid, which would be immobilisation and using compression bandages, and contact triple-0.</p> <p>“If you are unsure about what first aid measures to take, call triple-0, and they will walk you through what you need to do for the patient.”</p> <p>Eastern Brown Snakes are one of the most deadly snakes in the world, with the second most toxic venom. </p> <p>They can be found across the east of Australia including the Northern Territory, Queensland, South Australia, Victoria, NSW and the ACT.</p> <p>Brookes is believed to be the first person to have died from a snake bite in Australia this year. </p> <p>Last year, two people died from suspected eastern brown snake bites in Australia. </p> <p><em>Images: Facebook/ news.com.au</em></p>

It’s warming up and mozzies are coming. Here’s how to mosquito-proof your backyard

<p><em><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The weather is warming up and that means more time in the backyard. It also means more mosquitoes.</p> <p>Here are five ways you can mosquito-proof your backyard that <a href="https://theconversation.com/the-battle-against-bugs-its-time-to-end-chemical-warfare-111629">don’t rely on spraying insecticides</a>.</p> <h2>1. Get rid of water</h2> <p>Mosquitoes need water to complete their life cycles. They <a href="https://theconversation.com/feel-like-youre-a-mozzie-magnet-its-true-mosquitoes-prefer-to-bite-some-people-over-others-128788">need blood</a> – but water and warmth are just as important.</p> <p>Getting rid of water around your backyard will go a long way to keeping mosquitoes away. Water trapped in blocked roof gutters, drains and tarpaulin covering boats and trailers can be a great home for mosquitoes.</p> <p>Mosquitoes can exploit the tiniest of water sources too. It may just be the upturned lid of a discarded plastic drink bottle. If it traps water, mosquitoes will find it and lay eggs in it.</p> <p>Flush out your bird bath once a week to disrupt the mosquito’s life cycle.</p> <p>If you have a pond, installing a fountain will discourage mosquitoes. If you can’t keep water clean and circulating, consider filling it with sand and gravel to create an interesting garden bed for succulents or other plants.</p> <p>Mosquitoes will avoid clean and chlorinated swimming pools but will quickly move into “green pools”. If you’re not using your pool, consider <a href="https://www.krg.nsw.gov.au/Environment/Your-local-environment/Wildlife/Living-with-wildlife/Pool-to-pond/How-to-convert-your-pool">converting it to a “pond”</a> so that fish can help keep mosquito numbers down.</p> <h2>2. Screen up – windows, doors and rainwater tanks</h2> <p>If you can’t get rid of permanent water, at least stop mosquitoes getting to it (or you).</p> <p>Ensure <a href="https://www.brisbane.qld.gov.au/clean-and-green/natural-environment-and-water/water/water-smart-homes/rainwater-tanks/using-your-rainwater-tank">rainwater and septic tanks</a> have screens to stop mosquitoes entering.</p> <p>Screen windows and doors to stop mosquitoes entering the home. There are plenty of flexible screening options for windows, doors and balconies.</p> <p>If you live in a mosquito-prone area, creating a screened outdoor area (such as a pergola, courtyard, or balcony) will give you the opportunity to spend time outdoors without being hassled by mozzies.</p> <h2>3. Choose your garden plants carefully</h2> <p>Some plants <a href="https://bioone.org/journals/Journal-of-the-American-Mosquito-Control-Association/volume-25/issue-3/09-0016.1/Are-Commercially-Available-Essential-Oils-from-Australian-Native-Plants-Repellent/10.2987/09-0016.1.short">contain essential oils and other chemicals</a> that, when extracted and concentrated, provide protection against biting mosquitoes. But there isn’t a lot of evidence that the whole plant will keep mosquitoes away from your garden.</p> <p>Some types of plants are even marketed as “mozzie blockers” or “mosquito repelling”. But there isn’t <a href="https://www.veranda.com/outdoor-garden/a40592197/do-mosquito-repelling-plants-work/">any evidence of effectiveness</a>. In fact, some of these plants, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1440-6055.2009.00736.x">such as melaleucas</a>, also happen to be associated with <a href="https://academic.oup.com/jme/article/36/4/515/903838">hot spots of mosquito breeding</a> in coastal Australia.</p> <p>The plants to <em>avoid</em> around the home are those that help mosquitoes breed, such as <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1440-6055.2008.00641.x">bromeliads</a>, which trap water.</p> <h2>4. Encourage the animals that eat mosquitoes</h2> <p>Mosquitoes are food for a range of animals including birds, bats, fish, frogs, lizards, insects, spiders and <a href="https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2656.13965">dragonflies</a>. But don’t expect them to eat enough to keep all mosquitoes away.</p> <p>Bats are often promoted as a good “biological control” options but studies have shown mosquitoes are <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0077183">more likely to be a snack food</a> for small bats, not an irresistible staple of their diet.</p> <p>For garden ponds, frogs will eat a few adult mosquitoes but tadpoles of Australian frogs generally <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-21/issue-4/8756-971X(2006)21%5b492%3aTOFCAF%5d2.0.CO%3b2/TADPOLES-OF-FOUR-COMMON-AUSTRALIAN-FROGS-ARE-NOT-EFFECTIVE-PREDATORS/10.2987/8756-971X(2006)21%5B492:TOFCAF%5D2.0.CO;2.short">don’t eat many mosquito “wrigglers”</a>.</p> <p>Australian native fish <a href="https://pubmed.ncbi.nlm.nih.gov/15532929/">will readily eat mosquitoes</a> and may be useful for backyard ponds.</p> <p>But not all fish are good. While “mosquitofish” (aka “plague minnow”) is distributed overseas to assist in mosquito control, <a href="https://meridian.allenpress.com/australian-zoologist/article/30/3/316/134508/Does-predation-by-the-fish-Gambusia-holbrooki">it’s a disaster for local wildlife</a> and, <a href="https://www.dpi.nsw.gov.au/fishing/aquatic-biosecurity/pests-diseases/freshwater-pests/finfish-species/gambusia">along with other exotic fish species</a>, should not be released into local waterways.</p> <p><a href="https://link.springer.com/article/10.1007/s13157-019-01133-2">Healthier habitats promote fewer mosquitoes</a> so the best thing you can do is create habitats for the animals that eat mosquitoes.</p> <h2>5. Avoid traps and other gadgets</h2> <p>There are lots of devices purported to catch, kill, or repel mosquitoes from your garden. Some may catch a mosquito or two but they’re not very effective in knocking out big numbers.</p> <p>“Bug zappers” with bright lights will collect lots of flying insects. It’s just that mosquitoes make up a very small proportion of collections.</p> <p>Electrocuting devices, again, don’t seem to attract a lot of mosquitoes.</p> <p>Devices that <a href="https://theconversation.com/the-buzz-from-your-smartphone-wont-stop-mosquito-bites-92611">emit high frequency sounds</a> won’t help either.</p> <p>The best devices are typically those that are baited with carbon dioxide. These are a mainstay of state and territory <a href="https://www.health.nsw.gov.au/Infectious/mosquito-borne/Pages/surveillance.aspx">mosquito and arbovirus surveillance programs</a>. For a mosquito, the C0₂ tricks them into thinking the trap is a warm-blooded animal. The only problem is these can be expensive to run and don’t seem quite as effective for mosquito control <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-22/issue-3/8756-971X(2006)22%5b490%3aTATTFA%5d2.0.CO%3b2/Traps-and-Trapping-Techniques-for-Adult-Mosquito-Control/10.2987/8756-971X(2006)22%5B490:TATTFA%5D2.0.CO;2.short">unless used in large numbers</a>.</p> <h2>Yes, you’ll still need repellent</h2> <p>Perhaps the best way to avoid mosquito bites is to pick an insect repellent <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">recommended by health authorities</a> and <a href="https://theconversation.com/mozzies-biting-heres-how-to-choose-a-repellent-and-how-to-use-it-for-the-best-protection-150183">apply it</a> to ensure all exposed areas of skin are covered.

The cost of living is biting. Here’s how to spend less on meat and dairy

<p><em><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a></em></p> <p>The cost of groceries has risen substantially <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/monthly-consumer-price-index-indicator/may-2023">over the last year</a>. Food and non-alcoholic drinks rose by 7.9% in the year to May, with biggest increases in dairy products (15.1%), breads and cereals (12.8%) and processed foods (11.5%).</p> <p>Meat costs rose by 3.8%, but the absolute increase was high, with a kilo of fillet steak costing up to A$60 for a kilogram.</p> <p>Australians spend around <a href="https://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/6530.0Main+Features12009-10?OpenDocument">15% of their weekly food budget</a> on meat and half that (7.4%) on dairy products.</p> <p>About <a href="https://www.finder.com.au/cost-of-living-report">43% of householders</a> say grocery prices are a cause of financial stress, with half trying to reduce spending.</p> <p>So how can you save money on meat and dairy products without skimping on nutrients?</p> <h2>Meat</h2> <p><a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/lean-meat-and-poultry-fish-eggs-tofu-nuts-and-seeds-and">Meat</a> is a good source of protein, iron, zinc and vitamin B12.</p> <p>Recommendations are for a maximum of three serves of cooked lean red meat a week. This includes beef, lamb, veal, pork, or kangaroo, with a serve being 65g cooked, which equates to 90–100g raw. This means purchasing 270–300g per person per week.</p> <p>Check prices online and weekly specials. Less expensive cuts include oyster blade, chuck or rump steak ($22–$25 per kilogram). They can be tougher, making them better for casseroles or slow cook recipes, like this <a href="https://nomoneynotime.com.au/healthy-easy-recipes/clares-slow-cooked-beef-stroganoff">beef stroganoff</a>.</p> <p>One exception is mince because higher star, lower fat, more expensive products shrink less during cooking compared to regular mince, which shrinks by 25–30%.</p> <p>Extend casserole and mince dishes by adding vegetarian protein sources, such as dried or canned beans and legumes.</p> <p>A 400g can of red kidney beans costs about $1.50 and contains 240g of cooked beans, equivalent to 1.6 standard serves. Add a can of any type of legume (black, adzuki, cannelloni, butter, chickpeas, four-bean mix, brown lentils) or use dried versions that don’t need pre-soaking like dried red lentils at about $5 per kilogram.</p> <p>This <a href="https://www.glnc.org.au/resource/legumes-nutrition/">adds nutrients</a> including protein, B vitamins, iron, zinc, calcium, magnesium and dietary fibre.</p> <h2>Dairy</h2> <p>Dairy products are important sources of protein, calcium, magnesium, zinc, potassium and vitamins A, B2 and B12. <a href="https://www.eatforhealth.gov.au/food-essentials/how-much-do-we-need-each-day/recommended-number-serves-adults">Australian recommendations</a> are for two to three serves a day for adults and four serves for women over 50. One serve is <a href="https://www.eatforhealth.gov.au/food-essentials/how-much-do-we-need-each-day/serve-sizes">equivalent to</a> a cup of milk or 40g cheese.</p> <p>Fresh milk costs between $1.50 and $3.00 per litre depending on type and brand, while UHT milk is cheaper, about $1.60 per litre. It’s even cheaper to buy powdered milk ($10 per kilogram pack, which makes ten litres), equating to $1 per litre.</p> <p>Making yoghurt at home costs about $5–6 per kilogram using a powder mix and yoghurt maker ($25). Once set, divide into smaller tubs yourself. Use as a substitute for cream or sour cream.</p> <p>Fresh yoghurt varies from $11–$18 per kilogram, with individual serves and flavoured varieties more expensive (but not always). Compare per kilogram or per 100g prices and check for specials.</p> <p>Cheese prices vary a lot so compare prices per kilogram. As a guide, block cheese is cheaper than pre-sliced or grated cheese. Home brand products are cheaper than branded ones. Mature cheeses are more expensive and processed cheese least expensive. But, if you cut block cheese really thick you end up using more. Block cheese ranges from $15 to $30 a kilogram, while packets of pre-sliced cheese vary from $18 to over $30.</p> <p>Pre-grated cheeses range from $14 to $30 per kilo, with most around $20, and processed cheese varies from $10 to $15. Extend grated cheese by mixing with grated carrot (about $2 a kilogram) and use as a topper for tacos, wraps, pasta and pizza. Use processed cheese slices for toasted sandwiches. Most recipes work adding less cheese than specified.</p> <p>A high-calcium alternative to cheese in sandwiches is canned salmon, but at $15–$30 per kilogram ($6–$7 per 210g can) you add variety but may not save money.</p> <h2>3 tips to save on your food bills</h2> <p><strong>1.

8 bite-sized renovations you can do on the weekend

<p>We’re all time poor but that doesn’t mean you have to develop renovation inertia. By chunking down the big tasks you need to do around your home into bite-sized, weekend-worthy nibbles you can power through a number of renovation items piece by manageable piece.</p> <p><strong>1. Replace your handles</strong></p> <p>Upgrading your old, tired <span style="text-decoration: underline;"><strong><a href="https://www.domain.com.au/news/why-reddit-is-losing-it-over-doorknobs-20160323-gnpe5q/" target="_blank" rel="noopener">door handles</a></strong></span> is as simple as measuring the distance between the holes and searching online or in store to find a straight replace. Unscrew the old ones, hanging onto the existing screws, as otherwise you may have to cut the ones supplied with the new handles to size, and screw the new ones in place. Simple.</p> <p><strong>2. Changing cupboard fronts</strong></p> <p>A wonderful visual upgrade, you need to check that your kitchen has standard-sized cupboards for this to be an easy weekend upgrade. Standard cupboard and drawer sizes will have plenty of options in stores and online. You’ll need to check the location of hinges, the height and width of fronts and the condition of your carcasses but by unscrewing and replacing cupboards you can transform your kitchen or bathroom cabinets completely. You’ll find some <strong><span style="text-decoration: underline;"><a href="https://www.domain.com.au/news/cabinet-fever-on-the-rise-20120706-21kkk/" target="_blank" rel="noopener">interesting colour, texture and pattern options</a></span></strong> The only impediment is your creativity.</p> <p><strong>3. Paint your doors</strong></p> <p>While painting your whole home might be a bit more than you can manage in one sitting, a nice bite-sized job is to apply a couple of coats of <span style="text-decoration: underline;"><strong><a href="https://www.domain.com.au/news/for-the-love-of-the-coloured-front-door-20151127-gl5boi/" target="_blank" rel="noopener">coloured paint to your existing internal and external doors</a></strong></span>. Sure, you might not get through them all in one weekend but you can chip away at this task after work or in the mornings and add amazing contrast and interest to your interior scheme. Remember to use an enamel paint for doors and timber work.</p> <p><strong>4. Replace your shower head and toilet seats</strong></p> <p>One of the things I do routinely when moving into a new property is replace the shower head with a new one. Most replacement shower heads come with thread tape and you don’t need to be a plumber to do this straight replace as it doesn’t interrupt the fitting connection. If you can manage that the toilet seat replacement is a cinch.</p> <p><strong>5. Regrouting tiles</strong></p> <p>Scrape out any old or worn grout and replace with a new colour or a replacement of the existing. A word to the wise – don’t grout floors in white as they will be mid grey in no time.</p> <p><strong>6. Replace bathroom accessories</strong></p> <p>Another quick trip to the hardware store or bathroom supplier and you can <span style="text-decoration: underline;"><strong><a href="https://www.domain.com.au/news/budget-bathroom-makeovers-can-make-big-difference-20150703-gi12es/" target="_blank" rel="noopener">give your bathroom a facelift</a></strong></span> to complement that lovely new shower head.</p> <p><strong>7. Fill gaps and scrapes</strong></p> <p>There are different fillers for different tasks. A quick-dry, all-purpose one like Selley’s Rapid Filler is great for scratches and scrapes on walls or filling in bumps in timber work before painting. Fill gaps between skirtings, cornices and walls with no more gaps. Use a two-part filler like builders bog for areas that need a more hard-wearing but still sandable solution.</p> <p><strong>8. Remove redundant “features” and install new ones</strong></p> <p>Pulling out old, dated or worn shelving and storage cabinets can free up wall space and liberate your rooms from a tired look. Installing wall hung units or floating shelves can give you an opportunity to <span style="text-decoration: underline;"><strong><a href="https://www.domain.com.au/advice/moving-house-how-to-let-it-go-declutter/" target="_blank" rel="noopener">clear your home of clutter</a></strong></span> or create a place for you to best display your favourite items.</p> <p><em>Written by Darren Palmer.

<p>A woman has shared her story of waking up from a coma to discover all four of her limbs had been amputated.</p> <p>Tatiana Timon, 35, was on a dream trip to Angola, South Africa, as part of a dance group, but her health took a turn for the worse when she arrived back home in Camberwell, South London.</p> <p>The 35-year-old had spent 10 days in Angola before flying home and within days her health had declined, leaving her extremely weak.</p> <p>Tatiana was rushed to hospital where doctors confirmed she had contracted a deadly form of malaria.</p> <p>She had contracted the disease from a mosquito bite while overseas in May 2022.</p> <p>Her condition quickly worsened and she was put into an induced coma after developing sepsis.</p> <p>“All of my friends and family were worried because the doctor was telling them that I was going to die, like I was about to die three times", she told <em>MyLondon</em>.</p> <p>In order to stop blood poisoning from spreading to her vital organs, doctors were forced to amputate all four limbs.</p> <p>“When I woke up from the coma I knew, I saw that I was in hospital, and I knew something had happened to me", she said.</p> <p>“At that time I didn’t know how bad it was, like I just knew something had happened.”</p> <p>Tatiana says she strives to come independent and is fitted with prosthetic arms and legs.</p> <p>She shares frequent updates on her Instagram page and vows to stay positive during this hard time.</p> <p>"Now even without limbs I know that I will go back to the gym”, she wrote on one post.</p> <p>“I am determined to go back to being my healthy self, mentally and physically.”</p> <p>Tatiana is currently fundraising with hopes of buying new prosthetics which come with a hefty price tag, costing up to $294,100.</p> <p>“A negative thing I can turn into a positive thing to make my life easier because I don’t like to stress.</p> <p>“It happened, so I need to deal with it.”</p> <p><em>Image credit: Instagram/Facebook</em></p>

Another Project host bites the dust

<p dir="ltr">First it was Carrie Bickmore, then Lisa Wilkinson and on Tuesday night’s episode another <em>Project</em> host announced their departure from the news program.</p> <p dir="ltr">Comedian and regular co-host on Channel 10’s news program Peter Helliar announced that he will be leaving the show after eight years. </p> <p dir="ltr">“These things come in threes and it’s time for me to say I will be leaving The Project soon,” he said.</p> <p dir="ltr">“It’s been something on my mind for a while. People will read into the situation however they want to read into it, but I feel like I need to create some space for some projects I want to work on.</p> <p dir="ltr">“I've been able to juggle over the years, you guys have seen me do How to Stay Married and stand-up and books over the years, but I feel like there are some new areas that I'm going into hopefully next year that I need to be present for.”</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">After nearly 8 years at the desk, Peter Helliar will be leaving The Project. Here is the moment he made the announcement. <a href="https://t.co/k1i19lWcM5">pic.twitter.com/k1i19lWcM5</a></p> <p>— The Project (@theprojecttv) <a href="https://twitter.com/theprojecttv/status/1594974702744707072?ref_src=twsrc%5Etfw">November 22, 2022</a></p></blockquote> <p dir="ltr">An emotional Helliar then quoted Carrie when she shared her news saying that he will also continue loving the show. </p> <p dir="ltr">“You said that you are glad you're leaving The Project while you still love it, and I still love this show. I really do,” he continued.</p> <p dir="ltr">“It means a lot to me. It's done amazing things for me. I interviewed Luke Skywalker once and that meant a lot, and I look forward to seeing what the show is like in the future.</p> <p dir="ltr">“I'm pretty sure there are no more announcements and I can't wait to see what you and Kyle and Jackie O do with the show next year,” he said to Waleed Aly.</p> <p dir="ltr">Helliar has another two more weeks on the show, while Carrie has four more days. She jokingly wished Waleed Aly good luck for remaining. </p> <p dir="ltr">But the real question now is, will Waleed Aly quit next?</p> <p dir="ltr">According to entertainment reporter Peter Ford, the program has received quite a bit of backlash in the past year that it would not be surprising if Aly quit next.</p> <p dir="ltr">“I can’t think of a TV show that has been as polarising and has divided opinion as much as The Project, but it’s not mandatory to watch,” he said.</p> <p dir="ltr">“It’s increasing and increasing, and partly it is because on Twitter, people love to be angry, they want to be outraged and they want to bring someone or something down, so you have to allow that haters are going to hate.</p> <p dir="ltr">“But The Project has become a brand name that seems to get people angry, and I don’t know why that is. It’s odd – nobody is being forced to watch it.”</p> <p dir="ltr">He did however say that Aly may get away with it because he doesn’t have social media and doesn’t acknowledge the bad press toward him. </p> <p dir="ltr"><em>Image: The Project</em></p>

Imminent arrival of huge "double-size" mosquitoes

<p>Aussies can’t seem to catch a break this year; between inflation, record-breaking weather events and interest rate hikes we’ve had it rough.</p> <p>If you were planning on summer being a welcome relief, think again and start making preparations for the shocking mosquito season that lies ahead - which is believed to be the worst in 30 years.</p> <p>The insect population numbers have skyrocketed, thanks to extreme wet weather, so you might want to stock up on the likes of bug spray and Aerogard.</p> <p>These fat, hungry, “double-size” bloodsuckers are making their way into major cities after wreaking havoc in the NSW Central West.</p> <p>"We are told this is what is expected after all of this rain, is the floodwaters recede, we get ponds, these pools of water, the female mozzies go on a frenzy, lay their eggs," Today reporter Sarah Stewart said.</p> <p>Stewart said Sydneysiders can expect an influx of the hungry insects in coming weeks, as conditions ripen for even more of the pests.</p> <p>"We are hearing from farmers if you work outside, they get on your hair, up your nose, they bite them through their hats even," she said.</p> <p>"Unfortunately, we are told they are going to head to Sydney to the coast, over the coming weeks."</p> <p>Just weeks ago, Associate Professor Cameron Webb from NSW Health Pathology told 9news.com.au that numbers are expected to explode once the weather officially warms up.</p> <p><em>Image: Nine News</em></p>

Why mozzies bite some more than others

<p dir="ltr">While summer brings with it days on the beach and nights outside enjoying the balmy weather, another, more unpleasant summer fixture also comes out in droves: mosquitoes.</p> <p dir="ltr">Although some of us dread being covered in itchy bites, there are others who mosquitoes seem to ignore - and now scientists have part of the answer explaining why.</p> <p dir="ltr">Researchers from Rockefeller University have found that mosquitoes are attracted to people based on the smell of their skin, created through a blend of particular acids.</p> <p dir="ltr">Focusing on Aedes aegypti, the mosquito which carries viruses such as dengue, yellow fever and Zika virus, the team used samples of human forearm odour collected on nylon stockings from 64 people, performing more than 2300 tests over 174 days across a three-year study.</p> <p dir="ltr">They found that people who were highly attractive to the mosquitoes had significantly higher levels of carboxylic acids which contribute to their skin odour.</p> <p dir="ltr">These carboxylic acids are produced when bacteria on the skin breaks down steroids and cholesterol secreted by our sweat glands.</p> <p dir="ltr">"We tested mosquito attraction to human skin odour and identified people who are exceptionally attractive or unattractive to mosquitoes," they wrote.</p> <p dir="ltr">"Chemical analysis revealed that highly attractive people produce significantly more carboxylic acids in their skin [than others]."</p> <p dir="ltr">They also noted that there weren’t any chemicals found in higher levels on the skin of less attractive people and argued that this supports the idea that people’s skin lack attractive odours, rather than emitting an odour that repels mosquitoes.</p> <p dir="ltr">As for why some people have higher levels of these chemicals in their skin odour than others, the researchers suggested that genetics may play a role.</p> <p dir="ltr">"Understanding why some humans are more attractive than others provides insights into what skin odorants are most important to the mosquito and could inform the development of more effective ... repellents," they wrote.</p> <p dir="ltr">The study, published in the journal <em><a href="https://doi.org/10.1016/j.cell.2022.09.034" target="_blank" rel="noopener">Cell</a></em>, isn’t the first time scientists have attempted to understand why some people are more attractive to mozzies than others - and there are plenty of reasons why.</p> <p dir="ltr">Mosquito researcher Dr Cameron Webb from the University of Sydney told the <em><a href="https://www.abc.net.au/news/2022-10-19/nt-mosquitoes-study/101548550" target="_blank" rel="noopener">ABC</a></em> it could be to do with genetics, as well as your temperature, your diet, whether you’re sweaty or even whether you’re pregnant.</p> <p dir="ltr">Dr Gordana Rasic, a senior mosquito research officer at QIMR Berghofer Medical Research Institute in Queensland, explained that the factors driving the behaviour of mozzies are “very complex”.</p> <p dir="ltr">"Mosquito brains are small but they still process signals from hundreds and hundreds of different receptors," she said. </p> <p dir="ltr">"Biting humans is specific to female mosquitoes — they need to bite humans and take blood in order to develop their egg and basically reproduce — so it's an absolutely essential instinct."</p> <p dir="ltr">While this study adds a new piece to the puzzle of mozzie behaviour, Dr Webb noted that this study focused on one mosquito species out of thousands of species around the world.</p> <p dir="ltr">"Even if you solve the problem for one mosquito, that doesn't mean the relationship and their willingness to bite people applies to all of the mozzies," he said. </p> <p><span id="docs-internal-guid-07911092-7fff-f285-028e-94767fc3f8aa"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Tragedy as Aussie boy dies from mosquito bite

<p>A nine-year-old boy from Western Australia has tragically died from dengue fever while on holiday with his family. </p> <p>Glenn Pulgadas had been on holiday with his parents, Glenn and Ryza, in the Philippines to see extended family when he was bitten by a mosquito.</p> <p>According to the <a title="www.abc.net.au" href="https://www.abc.net.au/news/2022-08-30/wa-boy-dies-dengue-fever-in-philippines-warning-travellers/101386032">ABC</a>, the boy began feeling unwell on August 12th and was admitted to hospital. </p> <p>He was described as being “weak in appearance” with headaches, fever, abdominal pain, vomiting and nose bleeds.</p> <p>Glenn then went into dengue shock syndrome which typically includes clamminess, a rapid weak pulse and narrowing of pulse pressure.</p> <p>These symptoms then led to organ failure, with Glenn tragically passing away on August 25th.</p> <p>The young boy is being remembered as "bright and bubbly" by all who knew him.</p> <p>“Glenn was a bright, bubbly, young boy who was so full of life and always had a smile on his face,” said family friend Danielle Zarzycki.</p> <p>Glenn's hometown community of Harvey has launched a <a title="www.gofundme.com" href="https://www.gofundme.com/f/glenn-pulgadas-memorial">GoFundMe</a> page to raise money for funeral expenses which has so far reached more than $9000.</p> <p>One of the top donators, who gave $1,000 to Glenn's family, is local St Anne’s School, where Glenn was a year three student. </p> <p>Dengue fever is spread via the bite of some species of mosquito. </p> <p>Three out of four people who contract dengue won’t even get sick, and for those who do the symptoms can be mild and they often recover in a matter of days.</p> <p>About one in 20 people who become sick with dengue will be hit by a severe form and in the worst cases, the disease can lead to shock, internal bleeding and death. </p> <p><em>Image credits: Facebook</em></p>

Where do all the mosquitoes go in the winter?

<p>Summer evenings by the pool, lake or BBQ mean mosquitoes. But what about during winter when we’re mostly indoors? As the weather cools, these bloodsucking pests are rarely seen.</p> <p>But where do they go?</p> <p><strong>Warm, wet conditions suit mosquitoes</strong></p> <p>Mosquitoes have complex life cycles that rely on water brought to <a href="https://theconversation.com/hidden-housemates-the-mosquitoes-that-battle-for-our-backyards-59072" target="_blank" rel="noopener">wetlands, flood plains, and water-holding containers</a> by seasonal rainfall. Depending on whether we’re experiencing a summer under the influence of <a href="https://theconversation.com/will-the-arrival-of-el-nino-mean-fewer-mosquitoes-this-summer-102496" target="_blank" rel="noopener">El Niño</a> or <a href="https://theconversation.com/la-nina-will-give-us-a-wet-summer-thats-great-weather-for-mozzies-147180" target="_blank" rel="noopener">La Niña</a>, mosquito populations will change in different ways.</p> <p>During warmer months, their life cycle lasts about a month. Eggs laid around water hatch and the immature mosquitoes go through four developmental stages. Larvae then change to pupae, from which an adult mosquito emerges, sits briefly on the water surface, and then flies off to buzz and bite and continue the cycle.</p> <p>Water is crucial but temperature is really important too. Unlike warm-blooded animals, mosquitoes can’t control their own body temperatures. The warmer it is, the more active mosquitoes will be. There’s usually more of them about too.</p> <p>But once cold weather arrives, their activity slows. They fly less, they don’t bite as often, they reproduce less, and their life cycle takes longer to complete.</p> <p>Temperature also plays a role in determining the ability of mosquitoes to <a href="https://www.frontiersin.org/articles/10.3389/fmicb.2020.584846/full" target="_blank" rel="noopener">spread viruses</a>.</p> <p>Cold weather isn’t great for mosquitoes but <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-ento-011613-162023" target="_blank" rel="noopener">millions of years of evolution</a> have given them a <a href="https://link.springer.com/article/10.1186/s13071-017-2235-0" target="_blank" rel="noopener">few tricks to survive</a>.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;rect=0%2C43%2C4883%2C3211&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/468677/original/file-20220614-21-qmcj4w.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><em><span class="caption">Ponds and puddles may be frozen but that doesn’t mean all mosquitoes have disappeared.</span> <span class="attribution"><a class="source" href="https://unsplash.com/photos/7UYnlgDyf0o" target="_blank" rel="noopener">Tom Keldenich/Unsplash</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/" target="_blank" rel="noopener">CC BY</a></span></em></figcaption></figure> <p><strong>Mosquitoes don’t disappear completely</strong></p> <p>On a sunny afternoon in winter, you may notice the occasional mosquito buzzing about in your backyard.

Fresh warnings after spread of mosquito-born disease

<p>Two NSW residents have fallen seriously ill and are currently being hospitalised with a mosquito-borne disease that can result in potentially severe neurological impacts, sparking warnings about avoiding bites.</p> <p>NSW Health on Monday evening said the patients were a man from Corowa and a child from Wentworth, both in the NSW-Victoria border region.</p> <p>The department said the man was in intensive care and the child had been discharged from the ICU but was staying in hospital because of the seriousness of their illness.</p> <p>Authorities are expecting more cases to be confirmed in the future and several people are undergoing further testing.</p> <p>Acting Chief Health Officer Marianne Gale urged NSW residents to take steps to avoid being bitten by mosquitos.</p> <p>"We are working closely with the NSW Department of Primary Industries and other states and territories to determine the extent to which the virus is circulating," Dr Gale said.</p> <p>"Unfortunately, our recent wet weather has led to very high mosquito numbers, so we need the community to be particularly vigilant and take steps to avoid mosquito bites.</p> <p>"We know mosquitoes are most active between dusk and dawn, and we need people planning activities near waterways or where mosquitoes are present to be especially cautious, particularly those in the vicinity of the Murray River and its branches."</p> <p>Australia's acting Chief Medical Officer Dr Sonya Bennett last week declared a national alert over the virus, which is spread through the bite of an infected mosquito. Fortunately, this disease cannot move directly from person to person.</p> <p>The virus is common in a wide swathe of Asia and the Western Pacific, including India, most of China, Indonesia, Papua New Guinea and Japan.</p> <p>Recent cases are the first time it's been identified in NSW in humans or animals, according to NSW Health.</p> <p>Most humans who contract the virus do not experience any symptoms or only experience mild symptoms like headaches or fever.</p> <p>But the worst affected may suffer inflammation of the brain, a sudden onset of vomiting, high fever and chills, severe headaches, sensitivity to light, neck stiffness and nausea.</p> <p><em>Image: Getty</em></p>

Shark bites are rare. Here are 8 things to avoid to make them even rarer

<p>Shark bite incidents are <a href="https://www.floridamuseum.ufl.edu/shark-attacks/odds/how-where-when/">rare</a> but traumatic. They’re usually followed by calls for <a href="https://affirmpress.com.au/publishing/sharks-a-history-of-fear-in-australia/">mitigation</a> <a href="https://www.int-res.com/abstracts/meps/v631/p165-179/">strategies</a>, some of which are dangerous or lethal to sharks – despite the fact most sharks are timid and actively <a href="https://www.researchgate.net/publication/266853603_Monitoring_the_effects_of_tourism_on_whale_shark_Rhincodon_typus_behaviour_in_Mozambique">avoid people</a>.</p> <p>The “<a href="https://www.daf.qld.gov.au/sharksmart">SharkSmart</a>” approach, adopted by the Queensland government, aims to educate and urge people to take responsibility for reducing the risk of shark bites by changing their own behaviour. But can humans change?</p> <p>To find out, we teamed up with three companies in the sailing charter industry in the Whitsundays area to better understand how people were using the environment, their knowledge of shark smart behaviours and to see if promoting SharkSmart behaviours led to change.</p> <p>We <a href="https://www.publications.qld.gov.au/dataset/queensland-shark-control-program/resource/27af7dc2-73c5-4752-81c0-d6c8374c92e1">found</a> people can and do change behaviour as a result of education – but for some, unfortunately, a “she’ll be right” attitude still prevails.</p> <p><a href="https://images.theconversation.com/files/381253/original/file-20210129-17-1tc89vl.jpg?ixlib=rb-1.1.0&amp;rect=0%2C0%2C3159%2C2090&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/381253/original/file-20210129-17-1tc89vl.jpg?ixlib=rb-1.1.0&amp;rect=0%2C0%2C3159%2C2090&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Sharks swim in clear waters." /></a> <span class="caption">People must take responsibility for reducing the risk of shark bites by changing their own behaviour.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Doing your part to be SharkSmart</h2> <p>Previous surveys had shown many water-users were already aware of many ways to reduce shark risk but there was <a href="https://www.australiangeographic.com.au/topics/wildlife/2018/10/experts-weigh-in-on-the-whitsundays-shark-encounters">room for improvement</a>.</p> <p>Many SharkSmart behaviours are well known, such as not swimming at dusk or dawn when sharks may be more prevalent.</p> <p>But we wanted to find out what else people were doing in the water and see if some key SharkSmart interventions made a difference. The interventions included:</p> <ul> <li>showing people a short <a href="https://www.youtube.com/watch?v=d17id9NOR6s&amp;feature=youtu.be">video</a> before they went out on the water</li> <li>putting stickers on boats to remind people how to reduce shark risk</li> <li>making SharkSmart brochures available to guests on boats</li> <li>dedicated waste disposal bags were given to two of the charter boat operators, with the third acting as a control group.</li> </ul> <p><iframe width="440" height="260" src="https://www.youtube.com/embed/d17id9NOR6s?wmode=transparent&amp;start=0" frameborder="0" allowfullscreen=""></iframe></p> <p>We did surveys before and after these SharkSmart tools were introduced to see what changed.</p> <p>We particularly wanted to know whether people were less likely to do eight things linked to higher shark risk in the Whitsundays area:</p> <p><strong>1. splashing in the water</strong></p> <p><strong>2. swimming alone</strong></p> <p><strong>3. swimming near fishers</strong></p> <p><strong>4. swimming at spots where shark bites have occurred in the past (in this case, in <a href="https://www.daf.qld.gov.au/business-priorities/fisheries/shark-control-program/whitsundays-plan">Cid Harbour</a>)</strong></p> <p><strong>5. throwing fish scraps in the water</strong></p> <p><strong>6. throwing burley (a type of bait, sometimes known as chum) in the water</strong></p> <p><strong>7. fishing near swimmers</strong></p> <p><strong>8. throwing food in the water.</strong></p> <p><a href="https://www.publications.qld.gov.au/dataset/queensland-shark-control-program/resource/27af7dc2-73c5-4752-81c0-d6c8374c92e1">Research</a> suggests that by <em>not</em> doing these eight things, we can make shark bites even rarer than they already are.</p> <p>As well as the before-and-after surveys, we captured a sample of rubbish coming back on shore. This was so we could get an idea of whether fish and meat were being stored or thrown overboard.</p> <p>We also wanted to see <em>where</em> and <em>when</em> risk might be higher. For example, snorkelling in a busy anchorage or where people are fishing may increase unnecessary dangers. The warmer months of September to December were mapped as potential higher risk for shark bites.</p> <h2>Our findings</h2> <p>We surveyed 228 tourists (92 pre- and 136 post-intervention) and found:</p> <ul> <li>a 8.9% reduction in splashing or making noise when swimming or snorkelling</li> <li>a 4.1% reduction in throwing fish scraps overboard and</li> <li>a 3.8% reduction in people fishing near people swimming.</li> </ul> <p><a href="https://images.theconversation.com/files/381250/original/file-20210129-23-462790.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/381250/original/file-20210129-23-462790.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="A poster shows SharkSmart behaviours." /></a> <span class="caption">A poster shows SharkSmart behaviours.</span> <span class="attribution"><span class="source">Queensland Government</span>, <span class="license">Author provided</span></span></p> <p>We found most people were aware of these six behaviours:</p> <ul> <li>following local signage</li> <li>having a buddy when swimming, diving or snorkelling</li> <li>avoiding swimming at dawn or dusk</li> <li>swimming in clear water</li> <li>keeping fish waste and food scraps out of the water where people swim</li> <li>avoiding swimming with schools of bait fish or diving birds.</li> </ul> <p>The lowest awareness was for the last one, but after our intervention we saw a 4.7% increase in knowledge of this behaviour.</p> <p>Although 100% of people were aware of the need to keep fish waste and food scraps out of the water, our pre-surveys between August and October last year found about one-third of tourists still disposed of fish scraps into the water. After the intervention, the share of people doing this dropped to 4-8%.</p> <h2>Shifting the ‘she’ll be right’ attitude</h2> <p>The good news is there is very high awareness of SharkSmart behaviours and most times, people didn’t throw burley in the water, fish near swimmers or swim in Cid Harbour.</p> <p>Unfortunately, some people continued to splash, swim alone and throw fish waste and food scraps in the water. Changing these norms among swimmers and boaties will take time.</p> <p>An attitude of “she’ll be right” still exists among some water users and this group may be the toughest to influence; it’s hard to shift attitudes about dangers among people with such a relaxed attitude to risk.</p> <p>In the Whitsundays and wider Australia, we are lucky to have some of the most incredible beaches, islands and reefs in the world. Most of us are willing to take a small calculated risk to swim in the ocean. Shark bite incidents are <a href="https://taronga.org.au/conservation-and-science/australian-shark-attack-file">extremely rare in Australia</a> but by making small changes, we can drive down the danger even further.</p> <p><em>Katie Frisch and Gemma Molinaro from Reef Ecologic contributed to this article.</em><!-- Below is The Conversation's page counter tag.

Can mosquitos spread coronavirus?

<p>The pathogens mosquitos spread by sucking our blood cause over half a million deaths each year and hundreds of millions of cases of severe illness.</p> <p>But there is no scientific evidence to suggest mosquitos are transmitting SARS-CoV-2, the virus that causes COVID-19.</p> <p>While there are many things we have yet to know about the coronavirus, current research supports that it’s highly unlikely a mosquito will pick up the virus by biting an infected person, let alone be able to pass it on.</p> <p>Mosquitos CAN transmit other viruses</p> <p>Female mosquitos need the nutrition found in blood to help develop their eggs. Viruses take advantage of this requirement as mosquitoes can easily move from host to host to transmit diseases.</p> <p>But for a mosquito to become infected, it first needs to bite an infected animal, such as a bird of kangaroo, or a person.</p> <p>The list of diseases a mosquito can transfer includes dengue, tallow fever, chikungunya, Zika and Ross River virus. They can also spread malaria, which is caused by a parasite.</p> <p>But they cannot transmit other viruses such as HIV and Ebola.</p> <p>Coronavirus is mainly spread through droplets produced when people sneeze or cough, and by touched surfaces that are contaminated.</p> <p>While the virus is found in blood, there’s no evidence that can spread via mosquitos.</p> <p>So if a mosquito does pick up a substantial dose of the virus, the virus won’t be able to infect the mosquito itself.</p> <p>And if the mosquito isn’t infected, it won’t be able to transmit it to the next person.</p>

The virus also has to negotiate getting out of the gut, getting through the body, and then into the saliva. Each step in the process can be an impenetrable barrier for the virus.</p> <p>This may be straightforward for viruses that have adapted to this process but for others, the virus will perish in the gut or be excreted.</p> <p><span><a href="https://theconversation.com/profiles/cameron-webb-6736"><em>Cameron Webb</em></a><em>, Clinical Associate Professor and Principal Hospital Scientist, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></span></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why mosquitoes prefer to bite some people over others

<p>It’s always you, isn’t it? The person busy swatting away buzzing backyard mosquitoes or nursing an arm full of itchy red lumps after a weekend camping trip.</p> <p>You’re not imagining it – mosquitoes really are attracted to some people more than others.</p> <p><strong>Why do mosquitoes need blood?</strong></p> <p>Only female mosquitoes bite. They do it for the nutrition contained in blood, which helps develop their eggs.</p> <p>Mosquitoes don’t just get blood from people. They’re actually far more likely to get it from biting animals, <a href="https://theconversation.com/how-australian-wildlife-spread-and-suppress-ross-river-virus-107267">birds</a>, <a href="https://www.abc.net.au/news/2016-08-18/australian-geographic-nature-photographer-of-the-year-winners/7753248">frogs</a> and reptiles. They even <a href="https://www.nature.com/articles/s42003-018-0096-5">bite earthworms</a>.</p> <p>But some mosquitoes specifically target people. One of the worst culprits is the <em>Aedes aegypti</em> species, which spreads <a href="https://www.cdc.gov/dengue/index.html">dengue</a> and <a href="https://www.cdc.gov/yellowfever/">yellow fever</a> viruses.</p> <p>Another that prefers humans are the <em>Anopheles</em> mosquitoes, responsible for spreading the parasites that cause <a href="https://www.who.int/malaria/en/">malaria</a>.</p> <p><strong>How do mosquitoes find us?</strong></p> <p>Most mosquitoes will get their blood from whatever is around and don’t necessarily care if they’re biting one person or another.</p> <p>Although it’s our blood they’re after, there is no strong indicator they prefer a particular blood type over another. Some studies have <a href="https://academic.oup.com/jme/article/41/4/796/885285">suggested they prefer people with type O blood</a> but that’s unlikely to be the case for all types of mosquitoes.</p> <p>Whether we’re picked out of a crowd may come down to heavy breathing and skin smell.</p> <p>When they need blood, mosquitoes can pick up on the <a href="https://www.cambridge.org/core/journals/bulletin-of-entomological-research/article/role-of-carbon-dioxide-in-hostfinding-by-mosquitoes-diptera-culicidae-a-review/2506B86EF63852B2D02EC3FCEE1E3B8B">carbon dioxide</a> we exhale. Around the world, carbon dioxide is one of the most common “baits” used to attract and collect mosquitoes. If you’re exhaling greater volumes of carbon dioxide, you’re probably an easier target for mosquitoes.</p> <p>When the mosquito gets closer, she is <a href="https://www.sciencedirect.com/science/article/pii/S2214574517300342">responding to a range of stimuli</a>.</p> <p>Perhaps it’s <a href="https://www.sciencedirect.com/science/article/abs/pii/S1471492210002618">body heat and sweat</a>: exercise that increases body temperature and perspiration can attract mosquitoes.</p> <p>Perhaps it’s body size: studies indicate <a href="https://academic.oup.com/trstmh/article/96/2/113/1909983">pregnant women are more likely to be bitten</a> by mosquitoes.</p> <p>How hairy are you? Mosquitoes may have a tough job finding a path through to your skin if there is an abundance of body hair.</p> <p>More than anything else, though, it’s about the smell of your skin. Hundreds of chemicals are sweated out or emitted by our body’s bacteria. The <a href="https://www.sciencedirect.com/science/article/pii/S2214574517300536">cocktail of smells they create</a> will either attract or deter mosquitoes.</p> <p><strong>It’s not just who they bite but where</strong></p> <p>Mosquitoes could also have a preference for different parts of the body.</p> <p>One study showed mosquitoes are more attracted to hands and feet <a href="https://www.nature.com/articles/srep27141">than armpits</a>, but that just turned out to be because of deodorant residues.</p> <p>Mosquitoes may also be more attracted to our feet: studies have shown cheese sharing similar bacteria to that <a href="https://www.ncbi.nlm.nih.gov/pubmed/15275226">found between our toes</a> attracts mosquitoes!</p> <p><strong>Who is to blame for this misery?</strong></p> <p>It’s not your diet. There is no evidence that what you eat or drink will prevent mosquito bites. Some food or drink may subtly change how many mosquitoes are likely to bite you but it won’t make that much difference.</p> <p><a href="https://www.mdpi.com/2075-4450/9/4/129">Eating bananas</a> or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2832015/">drinking beer</a> has been shown to marginally increase the attraction of mosquitoes but the results aren’t enough to suggest any dietary change will reduce your mosquito bites. That’s why our supermarket shelves aren’t full of “mozzie repellent” pills.</p> <p>Your irresistibility to mosquitoes may not be your fault. Blame your parents. Studies have shown the chemicals responsible for the “<a href="https://europepmc.org/article/med/2230769">skin smell</a>” that attracts mosquitoes has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4406498/">a high level of heritability</a> when twins are exposed to biting mosquitoes.</p> <p><strong>What can you do about it?</strong></p> <p>We have to be careful about generalisations. There are thousands of types of mosquitoes around the world and all will have a different preference for what or who to bite. And the attraction of individuals and the scenario that plays out in one part of the world may be much different in another.</p> <p>Remember, it only takes one mosquito bite to transmit a pathogen that could make you sick.

“Suicide by cop”: Victorian police officer defends hitting disabled pensioner

<p>A Victorian Police officer said that he genuinely felt he was facing a “suicide by cop” scenario when he repeatedly hit a disabled pensioner with a baton and stood on his head during a welfare check.</p> <p>Pensioner John was also pepper sprayed during the ordeal with six police officers and the welfare check was ordered after he failed to return messages from a counsellor and withdrew from opioid medication.</p> <p>Senior Constable John Edney is one of three officers who are fighting assault charges over the September 2017 incident.</p> <p>"I did believe it was a real suicide by cop scenario," he told a contested hearing at Heidelberg Magistrates Court, according to<span> </span><a rel="noopener noreferrer" href="https://www.9news.com.au/national/victorian-police-officer-defends-hitting-disabled-pensioner-with-baton/a4596c15-6e83-4e8d-86a3-9319dbae5a29" target="_blank">9news</a>.</p> <p>Edney also said that he believed that John was armed and posed a threat to police officers.</p> <p>Video footage played to the court showed John answering a knock from Edney at his front door and said he wanted to be alone.</p> <p>"I don't want to f------ talk," he screams.</p> <p>"Get off my f------ property.</p> <p>"If you get the crowbar, you'll have to shoot me,” John continued.</p> <p>"I've been maced before and nothing happened."</p> <p>Edney said that his fear increased after that interaction and believed that John had weapons inside his house.</p> <p>"Part of the reason of going into his house was to check for weapons," he told prosecutor Diana Manova.</p> <p>"I did believe he was armed."</p> <p>The officers then pulled the pensioner to the ground and restrained him while Edney hit John’s calf with the baton six times and put his foot on his head.</p> <p>Edney said that both moves were justified as he was concerned John may “bite and spit” at police. When asked if he considered those actions appropriate, Edney said “Yes”.</p> <p>Senior Constable Brad McLeod and Senior Constable Florian Hilgart are also charged over the assault.</p>

Teachers saved student’s life after highly venomous snake bite

<p><span>Teachers of a Victorian primary school have been credited with saving the life of a 12-year-old student who was bitten twice by one of the world’s most venomous snakes.</span></p> <p><span>Deakin Hawke from West Gippsland was on a week-long school excursion to Canberra in October when he was attacked by an eastern brown snake, considered <a href="https://www.australiangeographic.com.au/topics/science-environment/2012/07/australias-10-most-dangerous-snakes/">the world’s second most toxic land snake</a>.</span></p> <p><span>Within ten minutes of being bitten in the leg, the boy collapsed and stopped breathing.</span></p> <p><span>Teacher Candie Ell If-Williams told <em><a href="https://7news.com.au/sunrise/on-the-show/teachers-quick-thinking-saves-student-after-deadly-snake-bite-on-school-camp-c-601494">Sunrise</a> </em>that she “went into autopilot” and applied a pressure immobilisation bandage to the leg to slow the venom from spreading while another began CPR. </span></p> <p><span>School principal Brad Wheller said he also took a photo of the snake for identification. “That’s when we made a call to 000,” he said.</span></p> <p><span>Hawke was rushed to a hospital and made a full recovery. Natalie Sindrey of St John Ambulance said the 12-year-old might not have survived had it not been for the first aid medical treatment from his teachers.</span></p> <p><span>“Straight after the bite they did an amazing job at doing the resuscitation, which is what they needed to do to keep him alive,” Sindrey told <em><a href="https://au.news.yahoo.com/teachers-save-students-life-after-deadly-snake-bite-during-camp-032807885.html">Sunrise</a></em>.</span></p> <p><span>According to <a href="https://www.flyingdoctor.org.au/about-the-rfds/stories/outback-survival-snakes-and-snakebites/">Royal Flying Doctor Service</a>, there are around 3,000 snakebites in Australia every year, with 550 hospitalisations.</span></p> <p><span>“Snakebite first aid can be very effective if done quickly,” the organisation said. “Bandage and immobilise the bite area and dial 000 for help immediately.”</span></p>
