Mosquitoes can spread the flesh-eating Buruli ulcer. Here’s how you can protect yourself

Each year, more and more Victorians become sick with a flesh-eating bacteria known as Buruli ulcer. Last year, 363 people presented with the infection, the highest number since 2004.

But it has been unclear exactly how it spreads, until now. New research shows mosquitoes are infected from biting possums that carry the bacteria. Mozzies spread it to humans through their bite.

What is Buruli ulcer?

Buruli ulcer, also known as Bairnsdale ulcer, is a skin infection caused by the bacterium Mycobacterium ulcerans.

It starts off like a small mosquito bite and over many months, slowly develops into an ulcer, with extensive destruction of the underlying tissue.

While often painless initially, the infection can become very serious. If left untreated, the ulcer can continue to enlarge. This is where it gets its “flesh-eating” name.

Thankfully, it’s treatable. A six to eight week course of specific antibiotics is an effective treatment, sometimes supported with surgery to remove the infected tissue.

Where can you catch it?

The World Health Organization considers Buruli ulcer a neglected tropical skin disease. Cases have been reported across 33 countries, primarily in west and central Africa.

However, since the early 2000s, Buruli ulcer has also been increasingly recorded in coastal Victoria, including suburbs around Melbourne and Geelong.

Scientists have long known Australian native possums were partly responsible for its spread, and suspected mosquitoes also played a role in the increase in cases. New research confirms this.

Our efforts to ‘beat Buruli’

Confirming the role of insects in outbreaks of an infectious disease is achieved by building up corroborating, independent evidence.

In this new research, published in Nature Microbiology, the team (including co-authors Tim Stinear, Stacey Lynch and Peter Mee) conducted extensive surveys across a 350 km² area of Victoria.

We collected mosquitoes and analysed the specimens to determine whether they were carrying the pathogen, and links to infected possums and people. It was like contact tracing for mosquitoes.

Molecular testing of the mosquito specimens showed that of the two most abundant mosquito species, only Aedes notoscriptus (a widespread species commonly known as the Australian backyard mosquito) was positive for Mycobacterium ulcerans.

We then used genomic tests to show the bacteria found on these mosquitoes matched the bacteria in possum poo and humans with Buruli ulcer.

We further analysed mosquito specimens that contained blood to show Aedes notoscriptus was feeding on both possums and humans.

To then link everything together, geospatial analysis revealed the areas where human Buruli ulcer cases occur overlap with areas where both mosquitoes and possums that harbour Mycobacterium ulcerans are active.

Stop its spread by stopping mozzies breeding

The mosquito in this study primarily responsible for the bacteria’s spread is Aedes notoscriptus, a mosquito that lays its eggs around water in containers in backyard habitats.

Controlling “backyard” mosquitoes is a critical part of reducing the risk of many global mosquito-borne disease, especially dengue and now Buruli ulcer.

You can reduce places where water collects after rainfall, such as potted plant saucers, blocked gutters and drains, unscreened rainwater tanks, and a wide range of plastic buckets and other containers. These should all be either emptied at least weekly or, better yet, thrown away or placed under cover.

There is a role for insecticides too. While residual insecticides applied to surfaces around the house and garden will reduce mosquito populations, they can also impact other, beneficial, insects. Judicious use of such sprays is recommended. But there are ecological safe insecticides that can be applied to water-filled containers (such as ornamental ponds, fountains, stormwater pits and so on).

Recent research also indicates new mosquito-control approaches that use mosquitoes themselves to spread insecticides may soon be available.

How to protect yourself from bites

The first line of defence will remain personal protection measures against mosquito bites.

Covering up with loose fitted long sleeved shirts, long pants, and covered shoes will provide physical protection from mosquitoes.

Applying topical insect repellent to all exposed areas of skin has been proven to provide safe and effective protection from mosquito bites. Repellents should include diethytolumide (DEET), picaridin or oil of lemon eucalyptus.

While the rise in Buruli ulcer is a significant health concern, so too are many other mosquito-borne diseases. The steps to avoid mosquito bites and exposure to Mycobacteriam ulcerans will also protect against viruses such as Ross River, Barmah Forest, Japanese encephalitis, and Murray Valley encephalitis.The Conversation

  • Avoiding Razor Burn, Ingrown Hairs & Other Shaving Irritation

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    How Does The Video Help?

    Dr. Simi Adedeji’s incredibly friendly persona makes this video (below) on avoiding skin irritation, ingrown hairs, and razor burn after shaving a pleasure to watch.

    To keep things simple, she breaks down her guide into 10 simple tips.

    What Are The 10 Simple Tips?

    Tip 1: Prioritize Hydration. Shaving dry hair can lead to increased skin irritation, so Dr. Simi recommends moistening the hair by showering or using a warm, wet towel for 2-4 minutes before getting the razor out.

    Tip 2: Avoid Dry Shaving. Dry shaving not only removes hair but can also remove the protective upper layer of skin, which contributes to razor burn. To prevent this, simply use some shaving gel or cream.

    Tip 3: Keep Blades New and Sharp. This one’s simple: dull blades can cause skin irritation, whilst a sharp blade ensures a smoother and more comfortable shaving experience.

    Tip 4: Avoid Shaving the Same Area Repeatedly. Multiple passes over the same area can remove skin layers, leading to cuts and irritation. Aim to shave each area only once for safer results.

    Tip 5: Consider Hair Growth Direction. Shaving in the direction of hair growth results in less irritation, although it may not provide the closest shave.

    Tip 6: Apply Gentle Pressure While Shaving. Excessive pressure can lead to cuts and nicks. Use a gentle touch to reduce these risks.

    Tip 7: Incorporate Exfoliation into Your Routine. Exfoliating helps release trapped hairs and reduces the risk of ingrown hairs. For those with sensitive skin, it’s recommended to exfoliate either two days before or after shaving.

    Tip 8: Avoid Excessive Skin Stretching. Over-stretching the skin during shaving can cause hairs to become ingrown.

    Tip 9: Moisturize After Shaving. Shaving can compromise the skin barrier, leading to dryness. Using a moisturizer can be a simple fix.

    Tip 10: Regularly Rinse Your Blade. Make sure that, during the shaving process, you are rinsing your blade frequently to remove hair and skin debris. This keeps it sharp during your shave.

  • No, vitamin A does not prevent measles

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    As measles spreads in Texas, New Mexico, and other states, a Texas child died from measles for the first time in the United States since 2015. In a March 2 Fox News editorial, Health and Human Services Secretary Robert F. Kennedy Jr. hinted at the importance of vaccination and stated that good nutrition, including vitamin A, is a “best defense against most chronic and infectious illnesses.”

    However, doctors and public health professionals say that vitamin A is not a replacement for the measles, mumps, and rubella (MMR) vaccine. Vitamin A is sometimes used to treat measles in the hospital—particularly in developing countries where people with poor nutrition tend to be vitamin A deficient. Experts also say that taking vitamin A when your body does not need it can be dangerous. 

    “It’s really important to distinguish prevention and treatment, and measles can be prevented, and it can be prevented one way: through vaccination,” Dr. Preeti Malani, infectious disease physician and professor at the University of Michigan, tells PGN. “The best treatment is to not get measles in the first place.”

    Read on to learn the facts about vitamin A, what it’s used for, its risks, and what you should do to prevent measles. 

    What is vitamin A, and what does it have to do with measles? 

    Vitamin A is a fat-soluble vitamin, which means that it’s stored in the body’s fatty tissue and in the liver, and it’s absorbed with the fat in a person’s diet. Vitamin A helps with our vision, reproduction, growth, and immunity. 

    Vitamin A deficiency can increase the risk of death from measles, among other infections. The World Health Organization recommends it as a supplement along with vaccination for children at risk of vitamin A deficiency in developing countries. 

    However, vitamin A deficiency is rare in the U.S. because most people get enough of it through their diet. (Malani says that’s why research about the use of vitamin A to treat measles is limited in countries like the United States.)

    “Vitamin A deficiency is a major problem in developing nations, particularly those that don’t have access to staple foods that have vitamin A,” says Andrea Love, PhD, a biomedical scientist and founder of the health communication organization Immunologic, to PGN. “The problem is that that’s been kind of extrapolated to high-income countries [like the United States], where vitamin A deficiency is really not a concern.”

    Under Kennedy’s direction, the Centers for Disease Control and Prevention recently updated its guidance to recommend the use of vitamin A to treat severe measles in young children, but specifically in a hospital setting and under a doctor’s supervision.

    Does vitamin A prevent measles?

    No. Vitamin A does not prevent measles. The MMR vaccine is the best way to prevent a measles infection. 

    “Vitamin A is not an alternative to vaccination,” Malani adds. “We have a safe and highly effective vaccine that’s been available for decades—it will protect individuals [and] communities from an outbreak.”

    Are there any risks to taking vitamin A? 

    Yes. If your body doesn’t need extra vitamin A, there are risks. 

    According to the National Institutes of Health, taking too much vitamin A (specifically, the type found in supplements and some medications) can cause nausea, severe headaches, blurred vision, muscle aches, and problems with coordination. In severe cases, it can also lead to coma and death. Taking too much vitamin A while pregnant can cause birth defects. 

    “If you’re already getting sufficient vitamin A from your diet, then when you consume more than what you need, those levels are going to build up in your body, in your fat stores, in your tissues, and you’re going to be at risk of both acute and chronic toxicity,” adds Love. 

    Water-soluble vitamins like vitamin C “get filtered out by your kidneys and you would pee it out, but fat-soluble vitamins [like vitamin A], don’t get processed and excreted as quickly; they start to build up in the body,” she says. 

    What can I do to protect myself from measles? 

    The MMR vaccine is the best way to protect yourself from measles. The CDC recommends children get two doses of the MMR vaccine: the first dose between 12 and 15 months and the second one between 4 and 6 years old. 

    Experts recommend that adults who are not sure about their vaccination or immunity status against measles get at least one dose of the MMR vaccine. Additionally, adults who are at high risk for measles (like health care workers and people who travel internationally) may need two additional doses.

    According to the CDC, you can also get an MMR vaccine within 72 hours of initial exposure to measles, which can give you some protection or make your illness less severe. Additionally, there’s an antibody (a protective protein called immunoglobulin) that a doctor may recommend for high-risk people within six days of being exposed to measles

  • Knee Pain Won’t Get Better Unless You Fix This First

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Most knee pain is mechanical, caused by excessive stress or strain on specific parts of the knee joint. However, it’s weak glutes that are often the root cause of excess knee strain, because when glutes are weak, they fail to keep the pelvis level and legs aligned, leading to improper knee movement.

    The seat of the problem

    Weak glutes cause the pelvis to drop and the thigh bone to roll inwards (called “valgus knee”). This misalignment creates shearing forces and excessive pressure on different parts of the knee. However, it can usually be fixed, and the following exercises are recommended:

    1. Seated band abductions: use a resistance band around the thighs while seated. Push your knees apart, and hold for a few seconds.
    2. Glute bridge with resistance band: lie on your back with your feet flat and a resistance band around your thighs. Push your hips up into a bridge position, then press your knees outward against the band.
    3. Clamshell exercise: lie on your side, with your knees bent at 90°. Keep your body slightly tilted forward, then lift the top knee while keeping your heels together.
    4. Hip abductions (lateral leg raises): lie on your side, keeping your legs straight. Lift the top leg slightly backward and upward, leading with your heel.
    5. Standing hip abductions: stand upright, using a wall for support. Lift one leg sideways and slightly backward while keeping your spine straight. Unlike the other exercises, this one has the benefit of being doable almost anywhere.

    Kim Botteicher hardly thinks of herself as a criminal.

    On the main floor of a former Catholic church in Bolivar, Pennsylvania, Botteicher runs a flower shop and cafe.

    In the former church’s basement, she also operates a nonprofit organization focused on helping people caught up in the drug epidemic get back on their feet.

    The nonprofit, FAVOR ~ Western PA, sits in a rural pocket of the Allegheny Mountains east of Pittsburgh. Her organization’s home county of Westmoreland has seen roughly 100 or more drug overdose deaths each year for the past several years, the majority involving fentanyl.

    Thousands more residents in the region have been touched by the scourge of addiction, which is where Botteicher comes in.

    She helps people find housing, jobs, and health care, and works with families by running support groups and explaining that substance use disorder is a disease, not a moral failing.

    But she has also talked publicly about how she has made sterile syringes available to people who use drugs.

    “When that person comes in the door,” she said, “if they are covered with abscesses because they have been using needles that are dirty, or they’ve been sharing needles — maybe they’ve got hep C — we see that as, ‘OK, this is our first step.’”

    Studies have identified public health benefits associated with syringe exchange services. The Centers for Disease Control and Prevention says these programs reduce HIV and hepatitis C infections, and that new users of the programs are more likely to enter drug treatment and more likely to stop using drugs than nonparticipants.

    This harm-reduction strategy is supported by leading health groups, such as the American Medical Association, the World Health Organization, and the International AIDS Society.

    But providing clean syringes could put Botteicher in legal danger. Under Pennsylvania law, it’s a misdemeanor to distribute drug paraphernalia. The state’s definition includes hypodermic syringes, needles, and other objects used for injecting banned drugs. Pennsylvania is one of 12 states that do not implicitly or explicitly authorize syringe services programs through statute or regulation, according to a 2023 analysis. A few of those states, but not Pennsylvania, either don’t have a state drug paraphernalia law or don’t include syringes in it.

    Those working on the front lines of the opioid epidemic, like Botteicher, say a reexamination of Pennsylvania’s law is long overdue.

    There’s an urgency to the issue as well: Billions of dollars have begun flowing into Pennsylvania and other states from legal settlements with companies over their role in the opioid epidemic, and syringe services are among the eligible interventions that could be supported by that money.

    The opioid settlements reached between drug companies and distributors and a coalition of state attorneys general included a list of recommendations for spending the money. Expanding syringe services is listed as one of the core strategies.

    But in Pennsylvania, where 5,158 people died from a drug overdose in 2022, the state’s drug paraphernalia law stands in the way.

    Concerns over Botteicher’s work with syringe services recently led Westmoreland County officials to cancel an allocation of $150,000 in opioid settlement funds they had previously approved for her organization. County Commissioner Douglas Chew defended the decision by saying the county “is very risk averse.”

    Botteicher said her organization had planned to use the money to hire additional recovery specialists, not on syringes. Supporters of syringe services point to the cancellation of funding as evidence of the need to change state law, especially given the recommendations of settlement documents.

    “It’s just a huge inconsistency,” said Zoe Soslow, who leads overdose prevention work in Pennsylvania for the public health organization Vital Strategies. “It’s causing a lot of confusion.”

    Though sterile syringes can be purchased from pharmacies without a prescription, handing out free ones to make drug use safer is generally considered illegal — or at least in a legal gray area — in most of the state. In Pennsylvania’s two largest cities, Philadelphia and Pittsburgh, officials have used local health powers to provide legal protection to people who operate syringe services programs.

    Even so, in Philadelphia, Mayor Cherelle Parker, who took office in January, has made it clear she opposes using opioid settlement money, or any city funds, to pay for the distribution of clean needles, The Philadelphia Inquirer has reported. Parker’s position signals a major shift in that city’s approach to the opioid epidemic.

    On the other side of the state, opioid settlement funds have had a big effect for Prevention Point Pittsburgh, a harm reduction organization. Allegheny County reported spending or committing $325,000 in settlement money as of the end of last year to support the organization’s work with sterile syringes and other supplies for safer drug use.

    “It was absolutely incredible to not have to fundraise every single dollar for the supplies that go out,” said Prevention Point’s executive director, Aaron Arnold. “It takes a lot of energy. It pulls away from actual delivery of services when you’re constantly having to find out, ‘Do we have enough money to even purchase the supplies that we want to distribute?’”

    In parts of Pennsylvania that lack these legal protections, people sometimes operate underground syringe programs.

    The Pennsylvania law banning drug paraphernalia was never intended to apply to syringe services, according to Scott Burris, director of the Center for Public Health Law Research at Temple University. But there have not been court cases in Pennsylvania to clarify the issue, and the failure of the legislature to act creates a chilling effect, he said.

    Carla Sofronski, executive director of the Pennsylvania Harm Reduction Network, said she was not aware of anyone having faced criminal charges for operating syringe services in the state, but she noted the threat hangs over people who do and that they are taking a “great risk.”

    In 2016, the CDC flagged three Pennsylvania counties — Cambria, Crawford, and Luzerne — among 220 counties nationwide in an assessment of communities potentially vulnerable to the rapid spread of HIV and to new or continuing high rates of hepatitis C infections among people who inject drugs.

    Kate Favata, a resident of Luzerne County, said she started using heroin in her late teens and wouldn’t be alive today if it weren’t for the support and community she found at a syringe services program in Philadelphia.

    “It kind of just made me feel like I was in a safe space. And I don’t really know if there was like a come-to-God moment or come-to-Jesus moment,” she said. “I just wanted better.”

    Favata is now in long-term recovery and works for a medication-assisted treatment program.

    At clinics in Cambria and Somerset Counties, Highlands Health provides free or low-cost medical care. Despite the legal risk, the organization has operated a syringe program for several years, while also testing patients for infectious diseases, distributing overdose reversal medication, and offering recovery options.

    Rosalie Danchanko, Highlands Health’s executive director, said she hopes opioid settlement money can eventually support her organization.

    “Why shouldn’t that wealth be spread around for all organizations that are working with people affected by the opioid problem?” she asked.

    In February, legislation to legalize syringe services in Pennsylvania was approved by a committee and has moved forward. The administration of Gov. Josh Shapiro, a Democrat, supports the legislation. But it faces an uncertain future in the full legislature, in which Democrats have a narrow majority in the House and Republicans control the Senate.

    One of the bill’s lead sponsors, state Rep. Jim Struzzi, hasn’t always supported syringe services. But the Republican from western Pennsylvania said that since his brother died from a drug overdose in 2014, he has come to better understand the nature of addiction.

    In the committee vote, nearly all of Struzzi’s Republican colleagues opposed the bill. State Rep. Paul Schemel said authorizing the “very instrumentality of abuse” crossed a line for him and “would be enabling an evil.”

    After the vote, Struzzi said he wanted to build more bipartisan support. He noted that some of his own skepticism about the programs eased only after he visited Prevention Point Pittsburgh and saw how workers do more than just hand out syringes. These types of programs connect people to resources — overdose reversal medication, wound care, substance use treatment — that can save lives and lead to recovery.

    “A lot of these people are … desperate. They’re alone. They’re afraid. And these programs bring them into someone who cares,” Struzzi said. “And that, to me, is a step in the right direction.”

    At her nonprofit in western Pennsylvania, Botteicher is hoping lawmakers take action.

    “If it’s something that’s going to help someone, then why is it illegal?” she said. “It just doesn’t make any sense to me.”

  • Red Lentils vs Green Lentils – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing red lentils to green lentils, we picked the green.

    Why?

    Yes, they’re both great. But there are some clear distinctions!

    First, know: red lentils are, secretly, hulled brown lentils. Brown lentils are similar to green lentils, just a little less popular and with (very) slightly lower nutritional values, as a rule.

    By hulling the lentils, the first thing that needs mentioning is that they lose some of their fiber, since this is what was removed. While we’re talking macros, this does mean that red lentils have proportionally more protein, because of the fiber weight lost. However, because green lentils are still a good source of protein, we think the fat that green lentils have much more fiber is a point in their favor.

    In terms of micronutrients, they’re quite similar in vitamins (mostly B-vitamins, of which, mostly folate / vitamin B9), and when it comes to minerals, they’re similarly good sources of iron, but green lentils contain more magnesium and potassium.

    Green lentils also contain more antixoidants.

    All in all, they both continue to be very respectable parts of anyone’s diet—but in a head-to-head, green lentils do come out on top (unless you want to prioritize slightly higher protein above everything else, in which case, red).

  • Are you over 75? Here’s what you need to know about vitamin D

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Vitamin D is essential for bone health, immune function and overall wellbeing. And it becomes even more crucial as we age.

    New guidelines from the international Endocrine Society recommend people aged 75 and over should consider taking vitamin D supplements.

    But why is vitamin D so important for older adults? And how much should they take?

    OPPO Find X5 Pro/Unsplash

    Young people get most vitamin D from the sun

    In Australia, it is possible for most people under 75 to get enough vitamin D from the sun throughout the year. For those who live in the top half of Australia – and for all of us during summer – we only need to have skin exposed to the sun for a few minutes on most days.

    The body can only produce a certain amount of vitamin D at a time. So staying in the sun any longer than needed is not going to help increase your vitamin D levels, while it will increase your risk of skin cancer.

    But it’s difficult for people aged over 75 to get enough vitamin D from a few minutes of sunshine, so the Endocrine Society recommends people get 800 IU (international units) of vitamin D a day from food or supplements.

    Why you need more as you age

    This is higher than the recommendation for younger adults, reflecting the increased needs and reduced ability of older bodies to produce and absorb vitamin D.

    Overall, older adults also tend to have less exposure to sunlight, which is the primary source of natural vitamin D production. Older adults may spend more time indoors and wear more clothing when outdoors.

    As we age, our skin also becomes less efficient at synthesising vitamin D from sunlight.

    The kidneys and the liver, which help convert vitamin D into its active form, also lose some of their efficiency with age. This makes it harder for the body to maintain adequate levels of the vitamin.

    All of this combined means older adults need more vitamin D.

    Deficiency is common in older adults

    Despite their higher needs for vitamin D, people over 75 may not get enough of it.

    Studies have shown one in five older adults in Australia have vitamin D deficiency.

    In higher-latitude parts of the world, such as the United Kingdom, almost half don’t reach sufficient levels.

    This increased risk of deficiency is partly due to lifestyle factors, such as spending less time outdoors and insufficient dietary intakes of vitamin D.

    It’s difficult to get enough vitamin D from food alone. Oily fish, eggs and some mushrooms are good sources of vitamin D, but few other foods contain much of the vitamin. While foods can be fortified with the vitamin D (margarine, some milk and cereals), these may not be readily available or be consumed in sufficient amounts to make a difference.

    In some countries such as the United States, most of the dietary vitamin D comes from fortified products. However, in Australia, dietary intakes of vitamin D are typically very low because only a few foods are fortified with it.

    Why vitamin D is so important as we age

    Vitamin D helps the body absorb calcium, which is essential for maintaining bone density and strength. As we age, our bones become more fragile, increasing the risk of fractures and conditions like osteoporosis.

    Keeping bones healthy is crucial. Studies have shown older people hospitalised with hip fractures are 3.5 times more likely to die in the next 12 months compared to people who aren’t injured.

    Vitamin D may also help lower the risk of respiratory infections, which can be more serious in this age group.

    There is also emerging evidence for other potential benefits, including better brain health. However, this requires more research.

    According to the society’s systematic review, which summarises evidence from randomised controlled trials of vitamin D supplementation in humans, there is moderate evidence to suggest vitamin D supplementation can lower the risk of premature death.

    The society estimates supplements can prevent six deaths per 1,000 people. When considering the uncertainty in the available evidence, the actual number could range from as many as 11 fewer deaths to no benefit at all.

    Should we get our vitamin D levels tested?

    The Endocrine Society’s guidelines suggest routine blood tests to measure vitamin D levels are not necessary for most healthy people over 75.

    There is no clear evidence that regular testing provides significant benefits, unless the person has a specific medical condition that affects vitamin D metabolism, such as kidney disease or certain bone disorders.

    Routine testing can also be expensive and inconvenient.

    In most cases, the recommended approach to over-75s is to consider a daily supplement, without the need for testing.

    You can also try to boost your vitamin D by adding fortified foods to your diet, which might lower the dose you need from supplementation.

    Even if you’re getting a few minutes of sunlight a day, a daily vitamin D is still recommended.
