Bird Flu Is Bad for Poultry and Dairy Cows. It’s Not a Dire Threat for Most of Us — Yet.

Headlines are flying after the Department of Agriculture confirmed that the H5N1 bird flu virus has infected dairy cows around the country. Tests have detected the virus among cattle in nine states, mainly in Texas and New Mexico, and most recently in Colorado, said Nirav Shah, principal deputy director at the Centers for Disease Control and Prevention, at a May 1 event held by the Council on Foreign Relations.

A menagerie of other animals have been infected by H5N1, and at least one person in Texas. But what scientists fear most is if the virus were to spread efficiently from person to person. That hasn’t happened and might not. Shah said the CDC considers the H5N1 outbreak “a low risk to the general public at this time.”

Viruses evolve and outbreaks can shift quickly. “As with any major outbreak, this is moving at the speed of a bullet train,” Shah said. “What we’ll be talking about is a snapshot of that fast-moving train.” What he means is that what’s known about the H5N1 bird flu today will undoubtedly change.

With that in mind, KFF Health News explains what you need to know now.

Q: Who gets the bird flu?

Mainly birds. Over the past few years, however, the H5N1 bird flu virus has increasingly jumped from birds into mammals around the world. The growing list of more than 50 species includes seals, goats, skunks, cats, and wild bush dogs at a zoo in the United Kingdom. At least 24,000 sea lions died in outbreaks of H5N1 bird flu in South America last year.

What makes the current outbreak in cattle unusual is that it’s spreading rapidly from cow to cow, whereas the other cases — except for the sea lion infections — appear limited. Researchers know this because genetic sequences of the H5N1 viruses drawn from cattle this year were nearly identical to one another.

The cattle outbreak is also concerning because the country has been caught off guard. Researchers examining the virus’s genomes suggest it originally spilled over from birds into cows late last year in Texas, and has since spread among many more cows than have been tested. “Our analyses show this has been circulating in cows for four months or so, under our noses,” said Michael Worobey, an evolutionary biologist at the University of Arizona in Tucson.

Q: Is this the start of the next pandemic?

Not yet. But it’s a thought worth considering because a bird flu pandemic would be a nightmare. More than half of people infected by older strains of H5N1 bird flu viruses from 2003 to 2016 died. Even if death rates turn out to be less severe for the H5N1 strain currently circulating in cattle, repercussions could involve loads of sick people and hospitals too overwhelmed to handle other medical emergencies.

Although at least one person has been infected with H5N1 this year, the virus can’t lead to a pandemic in its current state. To achieve that horrible status, a pathogen needs to sicken many people on multiple continents. And to do that, the H5N1 virus would need to infect a ton of people. That won’t happen through occasional spillovers of the virus from farm animals into people. Rather, the virus must acquire mutations for it to spread from person to person, like the seasonal flu, as a respiratory infection transmitted largely through the air as people cough, sneeze, and breathe. As we learned in the depths of covid-19, airborne viruses are hard to stop.

That hasn’t happened yet. However, H5N1 viruses now have plenty of chances to evolve as they replicate within thousands of cows. Like all viruses, they mutate as they replicate, and mutations that improve the virus’s survival are passed to the next generation. And because cows are mammals, the viruses could be getting better at thriving within cells that are closer to ours than birds’.

The evolution of a pandemic-ready bird flu virus could be aided by a sort of superpower possessed by many viruses. Namely, they sometimes swap their genes with other strains in a process called reassortment. In a study published in 2009, Worobey and other researchers traced the origin of the H1N1 “swine flu” pandemic to events in which different viruses causing the swine flu, bird flu, and human flu mixed and matched their genes within pigs that they were simultaneously infecting. Pigs need not be involved this time around, Worobey warned.

Q: Will a pandemic start if a person drinks virus-contaminated milk?

Not yet. Cow’s milk, as well as powdered milk and infant formula, sold in stores is considered safe because the law requires all milk sold commercially to be pasteurized. That process of heating milk at high temperatures kills bacteria, viruses, and other teeny organisms. Tests have identified fragments of H5N1 viruses in milk from grocery stores but confirm that the virus bits are dead and, therefore, harmless.

Unpasteurized “raw” milk, however, has been shown to contain living H5N1 viruses, which is why the FDA and other health authorities strongly advise people not to drink it. Doing so could cause a person to become seriously ill or worse. But even then, a pandemic is unlikely to be sparked because the virus — in its current form — does not spread efficiently from person to person, as the seasonal flu does.

Q: What should be done?

A lot! Because of a lack of surveillance, the U.S. Department of Agriculture and other agencies have allowed the H5N1 bird flu to spread under the radar in cattle. To get a handle on the situation, the USDA recently ordered all lactating dairy cattle to be tested before farmers move them to other states, and the outcomes of the tests to be reported.

But just as restricting covid tests to international travelers in early 2020 allowed the coronavirus to spread undetected, testing only cows that move across state lines would miss plenty of cases.

Such limited testing won’t reveal how the virus is spreading among cattle — information desperately needed so farmers can stop it. A leading hypothesis is that viruses are being transferred from one cow to the next through the machines used to milk them.

To boost testing, Fred Gingrich, executive director of a nonprofit organization for farm veterinarians, the American Association of Bovine Practitioners, said the government should offer funds to cattle farmers who report cases so that they have an incentive to test. Barring that, he said, reporting just adds reputational damage atop financial loss.

“These outbreaks have a significant economic impact,” Gingrich said. “Farmers lose about 20% of their milk production in an outbreak because animals quit eating, produce less milk, and some of that milk is abnormal and then can’t be sold.”

The government has made the H5N1 tests free for farmers, Gingrich added, but they haven’t budgeted money for veterinarians who must sample the cows, transport samples, and file paperwork. “Tests are the least expensive part,” he said.

If testing on farms remains elusive, evolutionary virologists can still learn a lot by analyzing genomic sequences from H5N1 viruses sampled from cattle. The differences between sequences tell a story about where and when the current outbreak began, the path it travels, and whether the viruses are acquiring mutations that pose a threat to people. Yet this vital research has been hampered by the USDA’s slow and incomplete posting of genetic data, Worobey said.

The government should also help poultry farmers prevent H5N1 outbreaks since those kill many birds and pose a constant threat of spillover, said Maurice Pitesky, an avian disease specialist at the University of California-Davis.

Waterfowl like ducks and geese are the usual sources of outbreaks on poultry farms, and researchers can detect their proximity using remote sensing and other technologies. By zeroing in on zones of potential spillover, farmers can target their attention. That can mean routine surveillance to detect early signs of infections in poultry, using water cannons to shoo away migrating flocks, relocating farm animals, or temporarily ushering them into barns. “We should be spending on prevention,” Pitesky said.

Q: OK it’s not a pandemic, but what could happen to people who get this year’s H5N1 bird flu?

No one really knows. Only one person in Texas has been diagnosed with the disease this year, in April. This person worked closely with dairy cows, and had a mild case with an eye infection. The CDC found out about them because of its surveillance process. Clinics are supposed to alert state health departments when they diagnose farmworkers with the flu, using tests that detect influenza viruses, broadly. State health departments then confirm the test, and if it’s positive, they send a person’s sample to a CDC laboratory, where it is checked for the H5N1 virus, specifically. “Thus far we have received 23,” Shah said. “All but one of those was negative.”

State health department officials are also monitoring around 150 people, he said, who have spent time around cattle. They’re checking in with these farmworkers via phone calls, text messages, or in-person visits to see if they develop symptoms. And if that happens, they’ll be tested.

Another way to assess farmworkers would be to check their blood for antibodies against the H5N1 bird flu virus; a positive result would indicate they might have been unknowingly infected. But Shah said health officials are not yet doing this work.

“The fact that we’re four months in and haven’t done this isn’t a good sign,” Worobey said. “I’m not super worried about a pandemic at the moment, but we should start acting like we don’t want it to happen.”

    In health terms, we are often about fighting aging here. But to be more specific, what we’re fighting in those cases is not truly aging itself, so much as age-related decline.

    Karen Walrond makes a case that we’ve made from the very start of 10almonds (but she wrote a whole book about it), that there’s merit in looking at what we can and can’t control about aging, doing what we reasonably can, and embracing what we can’t.

    And yes, embracing, not merely accepting. This is not a downer of a book; it’s a call to revolution. It asks us to be proud of our grey hairs, to see our smile-lines around our eyes as the sign of a lived-in body, and even to embrace some of the unavoidable “actual decline” things as part of the journey of life. Maybe we’re not as strong as we used to be and now need a grippety-doodah to open jars; not everyone gets to live long enough to experience that! How lucky we are.

    Perhaps most importantly, she bids us be the change we want to see in the world, and inspire others with our choices and actions, and shake off ageist biases for good.

    Bottom line: if you want to foster a better attitude to aging not only for yourself, but also those around you, then this is a top-tier book for that.

  • If You’re Poor, Fertility Treatment Can Be Out of Reach

    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.

    Mary Delgado’s first pregnancy went according to plan, but when she tried to get pregnant again seven years later, nothing happened. After 10 months, Delgado, now 34, and her partner, Joaquin Rodriguez, went to see an OB-GYN. Tests showed she had endometriosis, which was interfering with conception. Delgado’s only option, the doctor said, was in vitro fertilization.

    “When she told me that, she broke me inside,” Delgado said, “because I knew it was so expensive.”

    Delgado, who lives in New York City, is enrolled in Medicaid, the federal-state health program for low-income and disabled people. The roughly $20,000 price tag for a round of IVF would be a financial stretch for lots of people, but for someone on Medicaid — for which the maximum annual income for a two-person household in New York is just over $26,000 — the treatment can be unattainable.

    Expansions of work-based insurance plans to cover fertility treatments, including free egg freezing and unlimited IVF cycles, are often touted by large companies as a boon for their employees. But people with lower incomes, often minorities, are more likely to be covered by Medicaid or skimpier commercial plans with no such coverage. That raises the question of whether medical assistance to create a family is only for the well-to-do or people with generous benefit packages.

    “In American health care, they don’t want the poor people to reproduce,” Delgado said. She was caring full-time for their son, who was born with a rare genetic disorder that required several surgeries before he was 5. Her partner, who works for a company that maintains the city’s yellow cabs, has an individual plan through the state insurance marketplace, but it does not include fertility coverage.

    Some medical experts whose patients have faced these issues say they can understand why people in Delgado’s situation think the system is stacked against them.

    “It feels a little like that,” said Elizabeth Ginsburg, a professor of obstetrics and gynecology at Harvard Medical School who is president-elect of the American Society for Reproductive Medicine, a research and advocacy group.

    Whether or not it’s intended, many say the inequity reflects poorly on the U.S.

    “This is really sort of standing out as a sore thumb in a nation that would like to claim that it cares for the less fortunate and it seeks to do anything it can for them,” said Eli Adashi, a professor of medical science at Brown University and former president of the Society for Reproductive Endocrinologists.

    Yet efforts to add coverage for fertility care to Medicaid face a lot of pushback, Ginsburg said.

    Over the years, Barbara Collura, president and CEO of the advocacy group Resolve: The National Infertility Association, has heard many explanations for why it doesn’t make sense to cover fertility treatment for Medicaid recipients. Legislators have asked, “If they can’t pay for fertility treatment, do they have any idea how much it costs to raise a child?” she said.

    “So right there, as a country we’re making judgments about who gets to have children,” Collura said.

    The legacy of the eugenics movement of the early 20th century, when states passed laws that permitted poor, nonwhite, and disabled people to be sterilized against their will, lingers as well.

    “As a reproductive justice person, I believe it’s a human right to have a child, and it’s a larger ethical issue to provide support,” said Regina Davis Moss, president and CEO of In Our Own Voice: National Black Women’s Reproductive Justice Agenda, an advocacy group.

    But such coverage decisions — especially when the health care safety net is involved — sometimes require difficult choices, because resources are limited.

    Even if state Medicaid programs wanted to cover fertility treatment, for instance, they would have to weigh the benefit against investing in other types of care, including maternity care, said Kate McEvoy, executive director of the National Association of Medicaid Directors. “There is a recognition about the primacy and urgency of maternity care,” she said.

    Medicaid pays for about 40% of births in the United States. And since 2022, 46 states and the District of Columbia have elected to extend Medicaid postpartum coverage to 12 months, up from 60 days.

    Fertility problems are relatively common, affecting roughly 10% of women and men of childbearing age, according to the National Institute of Child Health and Human Development.

    Traditionally, a couple is considered infertile if they’ve been trying to get pregnant unsuccessfully for 12 months. Last year, the ASRM broadened the definition of infertility to incorporate would-be parents beyond heterosexual couples, including people who can’t get pregnant for medical, sexual, or other reasons, as well as those who need medical interventions such as donor eggs or sperm to get pregnant.

    The World Health Organization defined infertility as a disease of the reproductive system characterized by failing to get pregnant after a year of unprotected intercourse. It terms the high cost of fertility treatment a major equity issue and has called for better policies and public financing to improve access.

    No matter how the condition is defined, private health plans often decline to cover fertility treatments because they don’t consider them “medically necessary.” Twenty states and Washington, D.C., have laws requiring health plans to provide some fertility coverage, but those laws vary greatly and apply only to companies whose plans are regulated by the state.

    In recent years, many companies have begun offering fertility treatment in a bid to recruit and retain top-notch talent. In 2023, 45% of companies with 500 or more workers covered IVF and/or drug therapy, according to the benefits consultant Mercer.

    But that doesn’t help people on Medicaid. Only two states’ Medicaid programs provide any fertility treatment: New York covers some oral ovulation-enhancing medications, and Illinois covers costs for fertility preservation, to freeze the eggs or sperm of people who need medical treatment that will likely make them infertile, such as for cancer. Several other states also are considering adding fertility preservation services.

    In Delgado’s case, Medicaid covered the tests to diagnose her endometriosis, but nothing more. She was searching the internet for fertility treatment options when she came upon a clinic group called CNY Fertility that seemed significantly less expensive than other clinics, and also offered in-house financing. Based in Syracuse, New York, the company has a handful of clinics in upstate New York cities and four other U.S. locations.

    Though Delgado and her partner had to travel more than 300 miles round trip to Albany for the procedures, the savings made it worthwhile. They were able do an entire IVF cycle, including medications, egg retrieval, genetic testing, and transferring the egg to her uterus, for $14,000. To pay for it, they took $7,000 of the cash they’d been saving to buy a home and financed the other half through the fertility clinic.

    She got pregnant on the first try, and their daughter, Emiliana, is now almost a year old.

    Delgado doesn’t resent people with more resources or better insurance coverage, but she wishes the system were more equitable.

    “I have a medical problem,” she said. “It’s not like I did IVF because I wanted to choose the gender.”

    One reason CNY is less expensive than other clinics is simply that the privately owned company chooses to charge less, said William Kiltz, its vice president of marketing and business development. Since the company’s beginning in 1997, it has become a large practice with a large volume of IVF cycles, which helps keep prices low.

    At this point, more than half its clients come from out of state, and many earn significantly less than a typical patient at another clinic. Twenty percent earn less than $50,000, and “we treat a good number who are on Medicaid,” Kiltz said.

    Now that their son, Joaquin, is settled in a good school, Delgado has started working for an agency that provides home health services. After putting in 30 hours a week for 90 days, she’ll be eligible for health insurance.

    One of the benefits: fertility coverage.

  • Switchcraft – by Dr. Elaine Fox

    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 do we successfully balance “a mind is like a parachute: it only works if it’s open”, with the importance of also actually having some kind of personal integrity and consistency?

    Dr. Fox recommends that we focus on four key attributes:

    • Mental agility
    • Self-awareness
    • Emotional awareness
    • Situational awareness

    If this sounds a little wishy-washy, it isn’t—she delineates and explains each in detail. And most importantly: how we can build and train each one.

    Mental agility, for example, is not about being able to rapidly solve chess problems or “answer these riddles three”. It’s more about:

    • Adaptability
    • Balancing our life
    • Challenging (and if appropriate, changing) our perspective
    • Developing our mental competence

    This sort of thing is the “meat” of the book. Meanwhile, self-awareness is more a foundational conscious knowledge of one’s own “pole star” values, while emotional awareness is a matter of identifying and understanding and accepting what we feel—anything less is self-sabotage! And situational awareness is perhaps most interesting:

    Dr. Fox advocates for “trusting one’s gut feelings”. With a big caveat, though!

    If we trust our gut feelings without developing their accuracy, we’re just going to go about being blindly prejudiced and often wrong. So, a whole section of the book is devoted to honing this and improving our ability to judge things as they really are—rather than as we expect.

    Bottom line: this book is a great tool for not only challenging our preconceptions about how we think, but giving us the resources to be adaptable and resilient without sacrificing integrity.

  • The Polyvagal Theory – by Dr. Stephen Porges

    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.

    Do you ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.

    Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.

    Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.

    The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.

    These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.

    And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.

    A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.

    Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book

  • Reishi Mushrooms: Which Benefits Do They Really Have?

    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.

    Reishi Mushrooms

    Another Monday Research Review, another mushroom! If we keep this up, we’ll have to rename it “Mushroom Monday”.

    But, there’s so much room for things to say, and these are fun guys to write about, as we check the science for any spore’ious claims…

    Why do people take reishi?

    Popular health claims for the reishi mushroom include:

    • Immune health
    • Cardiovascular health
    • Protection against cancer
    • Antioxidant qualities
    • Reduced fatigue and anxiety

    And does the science agree?

    Let’s take a look, claim by claim:

    Immune health

    A lot of research for this has been in vitro (ie, with cell cultures in labs), but promising, for example:

    Immunomodulating Effect of Ganoderma lucidum (Lingzhi) and Possible Mechanism

    (that is the botanical name for reishi, and the Chinese name for it, by the way)

    That’s not to say there are no human studies though; here it was found to boost T-cell production in stressed athletes:

    Effect of Ganoderma lucidum capsules on T lymphocyte subsets in football players on “living high-training low”

    Cardiovascular health

    Here we found a stack of evidence for statistically insignificant improvements in assorted measures of cardiovascular health, and some studies where reishi did not outperform placebo.

    Because the studies were really not that compelling, instead of taking up room (and your time) with them, we’re going to move onto more compelling, exciting science, such as…

    Protection against cancer

    There’s a lot of high quality research for this, and a lot of good results. The body of evidence here is so large that even back as far as 2005, the question was no longer “does it work” or even “how does it work”, but rather “we need more clinical studies to find the best doses”. Researchers even added:

    ❝At present, lingzhi is a health food supplement to support cancer patients, yet the evidence supporting the potential of direct in vivo anticancer effects should not be underestimated.❞

    ~ Yuen et al.

    Check it out:

    Anticancer effects of Ganoderma lucidum: a review of scientific evidence

    Just so you know we’re not kidding about the weight of evidence, let’s drop a few extra sources:

    By the way, we shortened most of those titles for brevity, but almost all of the continued with “by” followed by a one-liner of how it does it.

    So it’s not a “mysterious action” thing, it’s a “this is a very potent medicine and we know how it works” thing.

    Antioxidant qualities

    Here we literally only found studies to say no change was found, one that found a slight increase of antioxidant levels in urine. It’s worth noting that levels of a given thing (or its metabolites, in the case of some things) in urine are often quite unhelpful regards knowing what’s going on in the body, because we get to measure only what the body lost, not what it gained/kept.

    So again, let’s press on:

    Reduced fatigue and anxiety

    Most of the studies for this that we could find pertained to health-related quality of life for cancer patients specifically, so (while they universally give glowing reports of reishi’s benefits to health and happiness of cancer patients), that’s a confounding factor when it comes to isolating its effects on reduction of fatigue and anxiety in people without cancer.

    Here’s one that looked at it in the case of reduction of fatigue, anxiety, and other factors, in patients without cancer (but with neurathenia), in which they found it was “significantly superior to placebo with respect to the clinical improvement of symptoms”.

    Summary:

    • Reishi mushroom’s anti-cancer properties are very, very clear
    • There is also good science to back immune health claims
    • It also has been found to significantly reduce fatigue and anxiety in unwell patients (we’d love to see more studies on its benefits in otherwise healthy people, though)

    Spotlight: Saw Palmetto

    ❝Was very interested in the article on ginko bilboa as i moved into a home that has the tree growing in the backyard. Is there any way i can process the leaves to make a tea out of it.❞

    Glad you enjoyed! First, for any who missed it, here was the article on Ginkgo biloba:

    Ginkgo Biloba, For Memory And, Uh, What Else Again?

    Now, as that article noted, Ginkgo biloba seeds and leaves are poisonous. However, there are differences:

    The seeds, raw or roasted, contain dangerous levels of a variety of toxins, though roasting takes away some toxins and other methods of processing (boiling etc) take away more. However, the general consensus on the seeds is “do not consume; it will poison your liver, poison your kidneys, and possibly give you cancer”:

    Ginkgo biloba L. seed; A comprehensive review of bioactives, toxicants, and processing effects

    The leaves, meanwhile, are much less poisonous with their ginkgolic acids, and their other relevant poison is very closely related to that of poison ivy, involving long-chain alkylphenols that can be broken down by thermolysis, in other words, heat:

    Leaves, seeds and exocarp of Ginkgo biloba L. (Ginkgoaceae): A Comprehensive Review of Traditional Uses, phytochemistry, pharmacology, resource utilization and toxicity

    However, this very thorough examination of the potential health benefits and risks of ginkgo tea, comes to the general conclusion “this is not a good idea, and is especially worrying in elders, and/or if taking various medications”:

    Medicinal Values and Potential Risks Evaluation of Ginkgo biloba Leaf Extract (GBE) Drinks Made from the Leaves in Autumn as Dietary Supplements

    In summary:

    • Be careful
    • Avoid completely if you have a stronger-than-usual reaction to poison ivy
    • If you do make tea from it, green leaves appear to be safer than yellow ones
    • If you do make tea from it, boil and stew to excess to minimize toxins
    • If you do make tea from it, doing a poison test is sensible (i.e. start with checking for a skin reaction to a topical application on the inside of the wrist, then repeat at least 6 hours later on the lips, then at least 6 hours later do a mouth swill, then at least 12 hours later drink a small amount, etc, and gradually build up to “this is safe to consume”)

    For safety (and legal) purposes, let us be absolutely clear that we are not advising you that it is safe to consume a known poisonous plant, and nor are we advising you to do so.

    But the hopefully only-ever theoretical knowledge of how to do a poison test is a good life skill, just in case
