Coronavirus & Avian Flu Tidbits # 293, May 5, 2024


First, there is now a Resources Page here for the most commonly asked questions I'm getting.

Happy to continue to answer your questions/concerns as best I can, so don't be shy about that.


Overall, transmission is trending down. Mike Hoerger: “Transmission continues to decline. About 1 in 161 people in the U.S. are infectious, the lowest levels since July 1. Transmission levels are higher than during 27% of the pandemic… the over-reporting in real-time data lead me to believe there's a 50-50 chance we see a May ‘wavelet’ versus continued decline for a couple months.

WHO Overturns Dogma on Airborne Disease Spread. The CDC Might Not Act on It.

KFF Health News  By Amy Maxmen MAY 1, 2024

The WHO concluded that airborne transmission occurs as sick people exhale pathogens that remain suspended in the air, contained in tiny particles of saliva and mucus that are inhaled by others...

The change puts fresh emphasis on the need to improve ventilation indoors and stockpile quality face masks before the next airborne disease explodes. Far from a remote possibility, measles is on the rise this year and the H5N1 bird flu is spreading among cattle in several states. Scientists worry that as the H5N1 virus spends more time in mammals, it could evolve to more easily infect people and spread among them through the air.

Traditional beliefs on droplet transmission help explain why the WHO and the CDC focused so acutely on hand-washing and surface-cleaning at the beginning of the pandemic. ...

More than 3,600 health care workers died in the first year of the pandemic, many due to a lack of protection.

However, a committee advising the CDC [the HICPAC committee I have written about repeatedly] appears poised to brush aside the updated science when it comes to its pending guidance on health care facilities....

But the National Nurses United union obtained notes of the conversations through a public records request to the agency. The records suggest a push for more lax protection. “It may be difficult as far as compliance is concerned to not have surgical masks as an option,” said one unidentified member, according to notes from the committee’s March 14 discussion. Another warned that “supply and compliance would be difficult.”

The nurses’ union, far from echoing such concerns, wrote on its website, “The Work Group has prioritized employer costs and profits (often under the umbrella of ‘feasibility’ and ‘flexibility’) over robust protections.”

Immunocompromised still have disproportionate deaths from Covid:

Despite representing approximately 4% of the population, immunocompromised individuals still account for about a quarter of COVID-19 hospitalizations and deaths.

[This is part of why improving ventilation and what the HICPAC decides re masking and non-drug interventions is so important.]

Hospitals no longer required to report COVID-19 data to CDC

As of May 1. [How short-sighted is that???]

Action:  message HHS here if you want to request that COVID hospitalization data continue to be posted.

Please Support proposal (section P): CMS is proposing to replace the COVID-19 and Seasonal Influenza reporting standards for hospitals and CAHs with a new standard addressing acute respiratory illnesses to require that, beginning on October 1, 2024, hospitals and CAHs would have to electronically report information about COVID-19, influenza, and RSV. CMS is proposing that outside of a public health emergency (PHE), hospitals and CAHs would have to report these data on a weekly basis.

has antiviral activity against RNA viruses including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The mechanism appears to be suppression of protein translation via targeting the host mechanistic target of rapamycin pathway. In the COVID-OUT randomized trial for outpatient coronavirus disease 2019 (COVID-19), metformin reduced the odds of hospitalizations/death through 28 days by 58%, of emergency department visits/hospitalizations/death through 14 days by 42%, and of long COVID through 10 months by 42%.

Participants on metformin showed a 3.6-fold reduction in mean viral load compared

H5N1 in the USA 2024 Timeline:

as of April 26, 2024, the virus has spread to at least 34 dairy
herds in nine states (Texas, Kansas, New Mexico, Idaho, Michigan, Ohio, North Carolina, South Dakota, and Colorado)

Bird flu virus circulated in cows for four months before outbreak confirmed by USDA

The study’s authors suggest that the spread in cattle started from a single spillover event from birds in the Texas panhandle that may have happened in early December. The USDA didn’t confirm the presence of H5N1 in a Texas herd until March 25.

The USDA’s analysis found about two dozen mutations that have arisen in the H5N1 virus as it has circulated in dairy cattle that are known to make influenza viruses more deadly or more likely to be able to infect humans.

The 2 newly reported outbreaks in cattle occurred in NM & were apparently confirmed on or before April 17, but only posted publicly April 30.

Do Our Flu Antivirals Work on H5N1?

Probably, but testing is beginning.

The testing of virus from the one known human patient confirmed that "the H5N1 virus was susceptible to all commercially available FDA-approved and recommended neuraminidase inhibitors," (This includes oseltamivir (Tamiflu), zanamivir (Relenza), and peramivir (Rapivab). Testing is pending for the polymerase inhibitor baloxavir (Xofluza).

H5N1: Reduced susceptibility to neuraminidase inhibitors

If this were to spread, it could render flu drugs in stockpile less effective. There are not many alternatives in abundant supply. - Rick Bright also:
This virus can change easily, can spread swiftly, and cause great harm. There has never been such widespread of this virus among mammals. We cannot be overly confident in our current vaccine / antiviral preparedness posture. We need to do more. Now is the time to act, not when there are more cases...

The current narrative is a bit overly confident they have things under control with 4+ year old candidate vaccine virus. This will be a suboptimal match to what would take off in 2024. It’s best to update the CVV now while we have time. We need the best vaccine in the fight, not one left over from 2020. Btw, ask @CDCDirector to release update seasonal flu vax efficacy from this season, for all ages....

Imp to note this likely originated from a single/limited infection (birds to dairy cattle in Texas), within a confined area. Meaning also, this could’ve been detected, contained, halted in a single area. It was likely spread across the country by transporting sick/infected cows.

Out of 33 dairy farms in 8 U.S. states (+1 dairy farm in Colorado), 23 people have been tested for highly pathogenic avian influenza H5N1 by states. Less than 1 person per farm. This seems a clear answer to the question: “Are we testing enough for H5N1?”

Unresolved questions:

How widespread is the virus in dairy cattle?

There's been little testing: preliminary results from nationwide samples of retail milk indicate about one in five samples are positive for viral traces (not live virus)

How exactly is the virus spreading?

Not clear. "We don't know if it's [surface] transmission. We don't know if there's aerosolization of the milk."

The USDA has also noted another concerning development — that there have been some instances of the virus moving from domesticated poultry to cattle.

Since 2022, there have been 26 human cases of H5N1 virus infection reported worldwide.

[Very little testing of farm workers has been done--CDC can't go in w/o invitation from the State. Many workers don't want to get tested.]

Also: Celine Gounder: 4/25

Are pigs being tested? Pigs are the mixing vessel for bird and human flu strains. Historically, when they’ve mixed, the result has been scary Frankenstein flu strains that can cause epidemics or pandemics.

How much asymptomatic spread is occurring? Among cows? & to people?

What’s being done with milk from infected cows that’s known to be contaminated? That milk should be pasteurized and disposed of in such a way that other animals and humans won’t be exposed or infected.

How are pasteurization facilities inspected and by whom? How do we know it’s working and being done correctly? What’s the oversight?

Are workers being given personal protective equipment? And are they wearing it to protect themselves against infection?

Why has it been so hard for government agencies to give us a more complete picture of this outbreak?

the cats died shortly after they were fed raw colostrum from sick cows, highlighting the risk of spread from cows to other animals through contaminated milk.

As suspected more than a month ago: H5 was detected at three [wastewater] plants located in a state with confirmed outbreaks of highly pathogenic avian influenza, H5N1 clade, in dairy cattle, suggesting a large fraction of Influenza A virus inputs were H5 subtypes. At two of the wastewater plants, industrial discharges containing animal waste, including milk byproducts, were permitted to discharge into sewers.

A study suggests that High-risk patients with COVID symptoms should use PCR rather than rapid tests

Study findings that reveal a sensitivity of 47% for COVID-19 rapid antigen tests (RATs) compared with reverse-transcription polymerase chain reaction (RT-PCR) tests during Omicron variant predominance should prompt clinicians to consider using the latter test in high-risk patients eligible for antiviral drugs, the authors say.

The study, published in Morbidity and Mortality Weekly Report, also showed a RAT sensitivity of 80% compared with viral culture.


PCRs are much more expensive and have a 1-2 day turnaround, so could well delay treatment. A likely better option is to do a rapid test (RAT) and, if negative and you are at high risk of complications, do a PCR.

In Virginia, the State Senate and House of Delegates have passed two bills guaranteeing the right to obtain contraceptives and engage in contraception -- and also creating a "cause of action" that be implemented against anyone who infringes on that right.

Because Mr. Youngkin wants a change that would allow medical providers to refuse coverage if contraception goes against their religious beliefs.

“Dissent must never lead to disorder” - President Biden.

From Reverend Dr. Martin Luther King Jr.’s “Letter From Birmingham Jail,” written in 1963:

“I have almost reached the regrettable conclusion that the Negro's great stumbling block in the stride toward freedom is not the White Citizen's Council-er or the Ku Klux Klanner, but the white moderate who is more devoted to "order" than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says "I agree with you in the goal you seek, but I can't agree with your methods of direct action;" who paternalistically feels he can set the timetable for another man's freedom; who lives by the myth of time and who constantly advises the Negro to wait until a "more convenient season."
