What experts are worrying about
The Missouri patient was sick enough to be hospitalized
...
The Missouri health department noted the adult patient “has underlying medical conditions,” but we don’t know their age or other risk factors.
...
It’s a promising sign that since the Missouri patient was hospitalized, there has not been a big bloom of flu-like illness in the state. “I don’t think there’s a whole iceberg out there that we don’t see,” says Nuzzo, but more details about the case would put her and other experts at ease.
...
Two weeks elapsed between the patient’s hospitalization and public health authorities’ announcements about the case
That long delay, says Nuzzo, suggests the US hasn’t switched on its sensitive flu surveillance system that would more rapidly identify bird flu infections in people with fever, cough, muscle aches, and other flu-like symptoms.
...
There’s very little transparency about how much infection is taking place on US dairy farms
...
Although bird flu has been reported in Missouri only in poultry farms and not on dairy farms, that doesn’t mean it isn’t there, said Nuzzo. It just means farmers may not be testing their workers or cows for the virus, or they aren’t reporting it.

The case was detected through the state’s seasonal flu surveillance system, indicating there could be more flying under the radar.
...
The main worry among experts is that an unexplained H5 infection raises the possibility of person-to-person transmission, something which the World Health Organization (WHO) warned would be of “enormous concern” due to its potential to trigger a global pandemic.
“This is how pandemics start,” Kruitka Kuppali, a spokesperson for the Infectious Disease Society of America and former WHO medical officer, told The Telegraph. “We need to scale up preparedness and response efforts.”
...
The 2009 swine flu pandemic was first detected in a similar way when two children in California with no known contact with pigs or each other were diagnosed with an H1N1 flu infection, previously circulating in swine.
Another theory is that the person consumed raw milk infected with H5N1, which has killed several barnyard cats who are thought to have consumed the liquid off farm floors in the US this year.
...
Lisa Cox, a spokesperson for the Missouri Health Department, said that the patient had not reported consuming raw milk. ...

Why won’t California name 3 Central Valley dairies with avian flu? They blame ‘lookie-loos’
BY ROBERT RODRIGUEZ
UPDATED SEPTEMBER 06, 2024 5:22 AM
Federal and state officials are keeping tight-lipped about the location of three Central Valley dairies that have tested positive for the highly pathogenic avian influenza.
And Michael Payne, a food animal veterinarian with the UC Davis Western Institute for Food Safety and Security, fully supports the practice.
Payne said revealing the counties or the name of the infected dairies increases the risk for potentially spreading the virus.
...
“When you are talking about biosecurity, what you don’t want is a bunch of lookie-loos, industry people and non-industry people coming and going from the dairy,”

I worry that one day we could wake up and have everyone look at
the U.S. and say, "If you thought that they had a poor response in
Wuhan with COVID, look at what you guys did with H5N1." And
they would be right.

Avian flu in cows and poultry continues to fly high in the U.S.
Published: 48 mins ago
Few states or nations put on a dairy cattle show like the World Dairy Expo in Madison, Wisconsin, where 50,000 visitors and vendors from nearly 100 countries will see 1,800 owners exhibiting 2,500 or so of the best dairy cattle in the galaxy.
Organizers of this year’s Expo, however, are working overtime to keep one party crasher out — highly pathogenic avian influenza, or bird flu. New rules, new testing and new paperwork for the Oct. 1-4 gathering are all aimed to keep it bird flu-free.
“(However,) in the unfortunate event of a positive Influenza A individual cow test,” explained Expo organizers Aug. 21, “we have been informed by the (state of) Wisconsin … that all cattle on site … will be temporarily quarantined.”
Moreover, if deemed necessary, “additional quarantine measures could be added.” Once the animals are allowed to leave the state for home, further quarantine may be required by other U.S. states and Canadian provinces.

The U.S. Department of Agriculture does offer voluntary testing of milk to determine the presence of bird flu in any dairy herd. So far, though, “of the roughly 24,000 farms that sell milk,” reported the New York Times recently, “only 30 are participating.”
Food Fix updated those low numbers in late August to note that now USDA “only shows 26 herds are participating,” or 0.1 percent of all herds nationwide. USDA, however, told the Times that the poor turnout shows “the system is working as designed.”
Indeed, for 26 herds, which only leaves 23,974 or so herds where it’s not working.

New federal report on Colorado bird flu cases urges health agencies to prepare for more infections among farm workers
Saturday, Aug 31, 2024
A new report on July's cluster of human H5 avian flu cases in Colorado urges U.S. public health agencies to be ready to respond to cases in agricultural workers who often have limited access to health care.
About a month ago, health agencies reported nine cases of the virus in infected farm workers in northeast Colorado, where they were euthanizing millions of infected birds on two poultry farms to prevent further spread. Six of the cases came from one operation, three were from another. That was on top of an additional case detected in a dairy worker earlier in July.
The Morbidity and Mortality Weekly Report (MMWR) from the federal Centers for Disease Control and Prevention, which is widely read in the public health world, focused on that group of farm workers. It was the first known cluster of human influenza A, also known as H5, cases in the U.S. associated with exposure at a poultry operation.
Public health workers with the Colorado Department of Public Health and Environment screened 663 workers who were culling the birds. Of that, 109 reported mild symptoms like conjunctivitis – commonly known as pink eye. Nine tested positive for the H5 avian flu and 19 tested positive for COVID-19. Those who tested positive for the H5 avian flu were treated with oseltamivir, a medication used to treat flu-like symptoms.

Vilsack authorizes first field trial for H5N1 cattle vaccine
Center of Veterinary Biologics accepting submissions for field studies.
Krissa Welshans, Livestock Editor
August 28, 2024
The next step regarding the potential development of an H5N1 virus vaccine for cattle is taking place, Agriculture Secretary Tom Vilsack said Wednesday during his address at the 2024 Farm Progress Show.
...
“We have a number of companies that have been working on vaccines, and one company has now presented sufficient information to the USDA to allow me to authorize, as I did this week, the first field trial of a vaccine for cattle H5N1 for safety purposes,” he told attendees.
It’s the next step in the development of a vaccine, “which hopefully we’ll be able to develop in the near term with the information we get from this trial.”
The trial, he said, will allow USDA to determine whether it can proceed to the next steps necessary “to ensure safe and effective use of the vaccine.”
USDA’s Center of Veterinary Biologics, which is overseeing these efforts, published a notice Wednesday that it is now accepting field trial applications for H5N1 vaccines that may be conducted outside of containment without terminal disposal of milk and other commodities.

[Greeley is in Weld County]
With Only Gloves To Protect Them, Farmworkers Say They Tend Sick Cows Amid Bird Flu
AUGUST 27, 2024
GREELEY, Colo. — In early August, farmworkers gathered under a pavilion at a park here for a picnic to celebrate Farmworker Appreciation Day. One sign that this year was different from the others was the menu: Beef fajitas, tortillas, pico de gallo, chips, beans — but no chicken.
Farms in Colorado had culled millions of chickens in recent months to stem the transmission of bird flu. Organizers filled out the spread with hot dogs.
No matter the menu, some dairy workers at the event said they don’t exactly feel appreciated. They said they haven’t received any personal protective equipment beyond gloves to guard against the virus, even as they or colleagues have come down with conjunctivitis and flu-like symptoms that they fear to be bird flu.
“They should give us something more,” one dairy worker from Larimer County said in Spanish. He spoke on the condition of anonymity out of fear he’d lose his job for speaking out. “What if something happens to us? They act as if nothing is wrong.”
-snip-
One dairy worker in Weld County, who spoke on the condition of anonymity for fear of losing his job, said his employer has not offered any protective equipment beyond gloves, even though he works with sick cows and raw milk.
His bosses asked the workers to separate sick cows from the others after some cows produced less milk, lost weight, and showed signs of weakness, he said. But the employer didn’t say anything about the bird flu, he said, or suggest they take any precautions for their own safety.
He said he bought protective goggles for himself at Walmart when his eyes became itchy and red earlier this summer. He recalled experiencing dizziness, headaches, and low appetite around the same time. But he self-medicated and pushed through, without missing work or going to a doctor.

There hasn't been a new #H5N1 #birdflu infected dairy herd
confirmed by @USDA this week. Only 2 last week. Does this
mean the outbreak is coming under control? Colorado &
Michigan's numbers are probably solid. Elsewhere refusal to test
means we don't know what we're not seeing.
