How America Lost Control of the Bird Flu, Setting the Stage for Another Pandemic


Keith Poulsen’s jaw dropped when farmers confirmed him photos on their cellphones on the World Dairy Expo in Wisconsin in October. A livestock veterinarian on the University of Wisconsin, Poulsen had seen sick cows earlier than, with their noses dripping and udders slack.

But the dimensions of the farmers’ efforts to deal with the sick cows shocked him. They confirmed movies of methods they constructed to hydrate lots of of cattle directly. In 14-hour shifts, dairy employees pumped gallons of electrolyte-rich fluids into ailing cows by way of steel tubes inserted into the esophagus.

“It was like watching a discipline hospital on an energetic battlefront treating lots of of wounded troopers,” he mentioned.

Nearly a yr into the primary outbreak of the fowl flu amongst cattle, the virus exhibits no signal of slowing. The U.S. authorities did not remove the virus on dairy farms when it was confined to a handful of states, by rapidly figuring out contaminated cows and taking measures to maintain their infections from spreading. Now a minimum of 875 herds throughout 16 states have examined constructive.

Experts say they’ve misplaced religion within the authorities’s potential to include the outbreak.

“We are in a horrible state of affairs and going right into a worse state of affairs,” mentioned Angela Rasmussen, a virologist on the University of Saskatchewan in Canada. “I don’t know if the fowl flu will develop into a pandemic, but when it does, we’re screwed.”

To perceive how the fowl flu acquired out of hand, KFF Health News interviewed almost 70 authorities officers, farmers and farmworkers, and researchers with experience in virology, pandemics, veterinary medication, and extra.

Together with emails obtained from native well being departments by way of public information requests, this investigation revealed key issues, together with deference to the farm business, eroded public well being budgets, neglect for the security of agriculture employees, and the sluggish tempo of federal interventions.

Case in level: The U.S. Department of Agriculture this month introduced a federal order to check milk nationwide. Researchers welcomed the information however mentioned it ought to have occurred months in the past — earlier than the virus was so entrenched.

“It’s disheartening to see so most of the similar failures that emerged through the covid-19 disaster reemerge,” mentioned Tom Bollyky, director of the Global Health Program on the Council on Foreign Relations.

Far extra fowl flu harm is inevitable, however the extent of it is going to be left to the Trump administration and Mother Nature. Already, the USDA has funneled greater than $1.7 billion into tamping down the fowl flu on poultry farms since 2022, which incorporates reimbursing farmers who’ve needed to cull their flocks, and greater than $430 million into combating the fowl flu on dairy farms. In coming years, the fowl flu could price billions of {dollars} extra in bills and losses. Dairy business specialists say the virus kills roughly 2% to five% of contaminated dairy cows and reduces a herd’s milk manufacturing by about 20%.

Worse, the outbreak poses the specter of a pandemic. More than 60 individuals within the U.S. have been contaminated, primarily by cows or poultry, however circumstances might skyrocket if the virus evolves to unfold effectively from individual to individual. And the recent news of an individual critically ailing in Louisiana with the fowl flu exhibits that the virus may be harmful.

Just a few mutations might permit the fowl flu to unfold between individuals. Because viruses mutate inside human and animal our bodies, every an infection is sort of a pull of a slot machine lever.

“Even if there’s solely a 5% probability of a fowl flu pandemic occurring, we’re speaking a couple of pandemic that most likely seems to be like 2020 or worse,” mentioned Tom Peacock, a fowl flu researcher on the Pirbright Institute within the United Kingdom, referring to covid. “The U.S. is aware of the chance however hasn’t completed something to sluggish this down,” he added.

Beyond the fowl flu, the federal authorities’s dealing with of the outbreak reveals cracks within the U.S. well being safety system that may permit different dangerous new pathogens to take root. “This virus is probably not the one which takes off,” mentioned Maria Van Kerkhove, director of the rising illnesses group on the World Health Organization. “But it is a actual fireplace train proper now, and it demonstrates what must be improved.”

A Slow Start

It could have been a grackle, a goose, or another wild fowl that contaminated a cow in northern Texas. In February, the state’s dairy farmers took notice when cows stopped making milk. They labored alongside veterinarians to determine why. In lower than two months, veterinary researchers recognized the extremely pathogenic H5N1 fowl flu virus because the offender.

Long listed amongst pathogens with pandemic potential, the fowl flu’s unprecedented unfold amongst cows marked a worrying shift. It had developed to thrive in animals which are extra like individuals biologically than birds.

After the USDA introduced the dairy outbreak on March 25, management shifted from farmers, veterinarians, and native officers to state and federal companies. Collaboration disintegrated virtually instantly.

Farmers apprehensive the federal government may block their milk gross sales and even demand sick cows be killed, as poultry are, mentioned Kay Russo, a livestock veterinarian in Fort Collins, Colorado.

Instead, Russo and different veterinarians mentioned, they have been dismayed by inaction. The USDA didn’t reply to their pressing requests to assist research on dairy farms — and for cash and confidentiality insurance policies to guard farmers from monetary loss in the event that they agreed to check animals.

The USDA introduced that it might conduct research itself. But researchers grew anxious as weeks handed with out outcomes. “Probably the largest mistake from the USDA was not involving the boots-on-the-ground veterinarians,” Russo mentioned.

Will Clement, a USDA senior adviser for communications, mentioned in an e-mail: “Since first studying of H5N1 in dairy cattle in late March 2024, USDA has labored swiftly and diligently to evaluate the prevalence of the virus in U.S. dairy herds.” The company offered analysis funds to state and nationwide animal well being labs starting in April, he added.

The USDA didn’t require lactating cows to be examined earlier than interstate journey till April 29. By then, the outbreak had unfold to eight different states. Farmers usually transfer cattle throughout nice distances, for calving in a single place, elevating in heat, dry climates, and milking in cooler ones. Analyses of the virus’s genes implied that it unfold between cows quite than repeatedly leaping from birds into herds.

Milking gear was a possible supply of an infection, and there have been hints of different prospects, equivalent to by way of the air as cows coughed or in droplets on objects, like work boots. But not sufficient information had been collected to understand how precisely it was occurring. Many farmers declined to check their herds, regardless of an announcement of funds to compensate them for misplaced milk manufacturing in May.

“There is a concern throughout the dairy farmer group that in the event that they develop into formally listed as an affected farm, they might lose their milk market,” mentioned Jamie Jonker, chief science officer on the National Milk Producers Federation, a company that represents dairy farmers. To his data, he added, this hasn’t occurred.

Speculation crammed data gaps. Zach Riley, head of the Colorado Livestock Association, mentioned he suspected that wild birds could also be spreading the virus to herds throughout the nation, regardless of scientific information suggesting in any other case. Riley mentioned farmers have been contemplating whether or not to put in “floppy inflatable males you see outdoors of automobile dealerships” to push back the birds.

Advisories from agriculture departments to farmers have been considerably speculative, too. Officials advisable biosecurity measures equivalent to disinfecting gear and limiting guests. As the virus stored spreading all through the summer time, USDA senior official Eric Deeble mentioned at a press briefing, “The response is satisfactory.”

The USDA, the Centers for Disease Control and Prevention, and the Food and Drug Administration offered a united entrance at these briefings, calling it a “One Health” strategy. In actuality, agriculture companies took the lead.

This was specific in an e-mail from a neighborhood well being division in Colorado to the county’s commissioners. “The State is treating this primarily as an agriculture situation (rightly so) and the general public well being half is secondary,” wrote Jason Chessher, public well being director in Weld County, Colorado. The state’s main agriculture county, Weld’s livestock and poultry business produces about $1.9 billion in gross sales every year.

Patchy Surveillance

In July, the fowl flu unfold from dairies in Colorado to poultry farms. To include it, two poultry operations employed about 650 temporary workers — Spanish-speaking immigrants as younger as 15 — to cull flocks. Inside hot barns, they caught contaminated birds, gassed them with carbon dioxide, and disposed of the carcasses. Many did the hazardous job with out goggles, face masks, and gloves.

By the time Colorado’s well being division requested if employees felt sick, 5 girls and 4 males had been contaminated. They all had crimson, swollen eyes — conjunctivitis — and several other had such signs as fevers, physique aches, and nausea.

State well being departments posted on-line notices providing farms protecting gear, however dairy employees in a number of states told KFF Health News that that they had none. They additionally hadn’t heard in regards to the fowl flu, by no means thoughts checks for it.

Studies in Colorado, Michigan, and Texas would later present that fowl flu circumstances had gone beneath the radar. In one analysis, eight dairy employees who hadn’t been examined — 7% of these studied — had antibodies towards the virus, an indication that that they had been contaminated.

Missed circumstances made it not possible to find out how the virus jumped into individuals and whether or not it was rising extra infectious or harmful. “I’ve been distressed and depressed by the shortage of epidemiologic information and the shortage of surveillance,” mentioned Nicole Lurie, an govt director on the worldwide group the Coalition for Epidemic Preparedness Innovations, who served as assistant secretary for preparedness and response within the Obama administration.

Citing “inadequate information,” the British authorities raised its assessment of the chance posed by the U.S. dairy outbreak in July from three to 4 on a six-tier scale.

Virologists all over the world mentioned they have been flabbergasted by how poorly the United States was monitoring the state of affairs. “You are surrounded by extremely pathogenic viruses within the wild and in livestock,” mentioned Marion Koopmans, head of virology at Erasmus Medical Center within the Netherlands. “If three months from now we’re at first of the pandemic, it’s no person’s shock.”

Although the fowl flu shouldn’t be but spreading swiftly between individuals, a shift in that route might trigger immense struggling. The CDC has repeatedly described the circumstances amongst farmworkers this yr as delicate — they weren’t hospitalized. But that doesn’t imply signs are a breeze, or that the virus can’t trigger worse.

“It doesn’t look nice,” wrote Sean Roberts, an emergency providers specialist on the Tulare County, California, well being division in an e-mail to colleagues in May. He described pictures of an contaminated dairy employee in one other state: “Apparently, the conjunctivitis that that is inflicting shouldn’t be a gentle one, however quite ruptured blood vessels and bleeding conjunctiva.”

Over the previous 30 years, half of round 900 individuals recognized with fowl flu all over the world have died. Even if the case fatality price is far decrease for this pressure of the fowl flu, covid confirmed how devastating a 1% demise price may be when a virus spreads simply.

Like different circumstances all over the world, the particular person now hospitalized with the fowl flu in Louisiana seems to have gotten the virus immediately from birds. After the case was introduced, the CDC released a statement saying, “A sporadic case of extreme H5N1 fowl flu sickness in an individual shouldn’t be surprising.”

‘The Cows Are More Valuable Than Us’

Local well being officers have been making an attempt exhausting to trace infections, in response to lots of of emails from county well being departments in 5 states. But their efforts have been stymied. Even if farmers reported contaminated herds to the USDA and agriculture companies instructed well being departments the place the contaminated cows have been, well being officers needed to depend on farm house owners for entry.

“The agriculture group has dictated the principles of engagement from the beginning,” mentioned Michael Osterholm, director of the Center for Infectious Disease Research and Policy on the University of Minnesota. “That was a giant mistake.”

Some farmers instructed well being officers to not go to and declined to watch their staff for indicators of illness. Sending employees to clinics for testing might go away them shorthanded when cattle wanted care. “Producer refuses to ship employees to Sunrise [clinic] to get examined since they’re too busy. He has pinkeye, too,” mentioned an e-mail from the Weld, Colorado, well being division.

“We know of 386 individuals uncovered — however we all know that is removed from the overall,” mentioned an e-mail from a public well being specialist to officers at Tulare’s well being division recounting a name with state well being officers. “Employers don’t need to run this by way of employee’s compensation. Workers are hesitant to get examined as a consequence of price,” she wrote.

A screenshot of an email that reads: “Hello Jason, / Please see update information below. / 1. Total number of dairies with cows tested positive for HPAI / a. 38 active; 2 closed; 0 suspect / 2. Number of dairies currently under monitoring (I presume the first two have fallen off the list) / a. CDP is currently attempting to monitor 26 dairies. 9 have refused, 3 have been returned to CDPHE/CDA for non-response. / 3. Total number of workers exposed (estimates are perfectly ok if we haven’t been able to contact dairies, just tell me if a number is an estimate) / a. 1250+ known workers plus an unknown amount exposed from dairies with whom we have not had contact or refused to provide information / 4. Total number of workers currently under monitoring (again estimates are ok) / a. ~1250 workers across 26 dairies”

Jennifer Morse, medical director of the Mid-Michigan District Health Department, mentioned native well being officers have been hesitant to use strain after the backlash many confronted on the peak of covid. Describing the 19 rural counties she serves as “very minimal-government-minded,” she mentioned, “should you attempt to work towards them, it is not going to go properly.”

Rural well being departments are additionally stretched skinny. Organizations specializing in outreach to farmworkers provided to help well being officers early within the outbreak, however months handed with out contracts or funding. During the primary years of covid, lagging authorities funds for outreach to farmworkers and different traditionally marginalized teams led to a disproportionate toll of the illness amongst individuals of coloration.

Kevin Griffis, director of communications on the CDC, mentioned the company labored with the National Center for Farmworker Health all through the summer time “to achieve each farmworker impacted by H5N1.” But Bethany Boggess Alcauter, the middle’s director of public well being packages, mentioned it didn’t obtain a CDC grant for fowl flu outreach till October, to the tune of $4 million. Before then, she mentioned, the group had very restricted funds for the duty. “We are definitely not reaching ‘each farmworker,’” she added.

Farmworker advocates additionally pressed the CDC for cash to offset employees’ monetary considerations about testing, together with paying for medical care, sick go away, and the chance of being fired. This amounted to a proposal of $75 each. “Outreach is clearly not an enormous precedence,” Boggess mentioned. “I hear again and again from employees, ‘The cows are extra invaluable than us.’”

The USDA has to this point put greater than $2.1 billion into reimbursing poultry and dairy farmers for losses as a result of fowl flu and different measures to regulate the unfold on farms. Federal companies have additionally put $292 million into growing and stockpiling fowl flu vaccines for animals and other people. In a controversial decision, the CDC has suggested towards providing those available to farmworkers.

“If you need to hold this from turning into a human pandemic, you deal with defending farmworkers, since that’s the most certainly manner that this may enter the human inhabitants,” mentioned Peg Seminario, an occupational well being researcher in Bethesda, Maryland. “The proven fact that this isn’t occurring drives me loopy.”

Nirav Shah, principal deputy director of the CDC, mentioned the company goals to maintain employees secure. “Widespread consciousness does take time,” he mentioned. “And that’s the work we’re dedicated to doing.”

As President-elect Donald Trump comes into workplace in January, farmworkers could also be even much less protected. Trump’s pledge of mass deportations could have repercussions whether or not they occur or not, mentioned Tania Pacheco-Werner, director of the Central Valley Health Policy Institute in California.

Many dairy and poultry employees reside within the U.S. with out authorization or on non permanent visas linked to their employers. Such precarity made individuals much less keen to see docs about covid signs or complain about unsafe working circumstances in 2020. Pacheco-Werner mentioned, “Mass deportation is an astronomical problem for public well being.”

Not ‘Immaculate Conception’

A swap flipped in September amongst specialists who examine pandemics as nationwide safety threats. A affected person in Missouri had the fowl flu, and nobody knew why. “Evidence factors to this being a one-off case,” Shah mentioned at a briefing with journalists. About a month later, the company revealed it was not.

Antibody checks discovered that an individual who lived with the affected person had been contaminated, too. The CDC didn’t understand how the 2 had gotten the virus, and the opportunity of human transmission couldn’t be dominated out.

Nonetheless, at an October briefing, Shah mentioned the general public danger remained low and the USDA’s Deeble mentioned he was optimistic that the dairy outbreak could possibly be eradicated.

Experts have been perturbed by such assured statements within the face of uncertainty, particularly as California’s outbreak spiked and a child was mysteriously contaminated by the identical pressure of virus discovered on dairy farms.

“This wasn’t simply immaculate conception,” mentioned Stephen Morrison, director of the Global Health Policy Center on the Center for Strategic and International Studies. “It got here from someplace and we don’t know the place, however that hasn’t triggered any form of reset in strategy — simply the identical form of complacency and low power.”

Sam Scarpino, a illness surveillance specialist within the Boston space, puzzled what number of different mysterious infections had gone undetected. Surveillance outdoors of farms was even patchier than on them, and fowl flu checks have been exhausting to get.

Although pandemic specialists had recognized the CDC’s singular maintain on testing for brand new viruses as a key clarification for why America was hit so exhausting by covid in 2020, the system remained the identical. Bird flu checks could possibly be run solely by the CDC and public well being labs till this month, despite the fact that industrial and tutorial diagnostic laboratories had inquired about operating checks since April. The CDC and FDA ought to have tried to assist them alongside months in the past, mentioned Ali Khan, a former high CDC official who now leads the University of Nebraska Medical Center College of Public Health.

As winter units in, the fowl flu turns into tougher to identify as a result of affected person signs could also be mistaken for the seasonal flu. Flu season additionally raises a danger that the 2 flu viruses might swap genes in the event that they infect an individual concurrently. That might kind a hybrid fowl flu that spreads swiftly by way of coughs and sneezes.

A sluggish response to rising outbreaks could merely be a brand new, unlucky norm for America, mentioned Bollyky, on the Council on Foreign Relations. If so, the nation has gotten fortunate that the fowl flu nonetheless can’t unfold simply between individuals. Controlling the virus might be a lot tougher and costlier than it might have been when the outbreak was small. But it’s doable.

Agriculture officers might begin testing each silo of bulk milk, in each state, month-to-month, mentioned Poulsen, the livestock veterinarian. “Not one and completed,” he added. If they detect the virus, they’d want to find out the affected farm in time to cease sick cows from spreading infections to the remainder of the herd — or a minimum of to different farms. Cows can unfold the fowl flu earlier than they’re sick, he mentioned, so pace is essential.

Curtailing the virus on farms is one of the simplest ways to stop human infections, mentioned Jennifer Nuzzo, director of the Pandemic Center at Brown University, however human surveillance should be stepped up, too. Every clinic serving communities the place farmworkers stay ought to have quick access to fowl flu checks — and be inspired to make use of them. Funds for farmworker outreach should be boosted. And, she added, the CDC ought to change its place and supply farmworkers fowl flu vaccines to guard them and push back the possibility of a hybrid fowl flu that spreads rapidly.

The rising variety of circumstances not linked to farms indicators a necessity for extra testing on the whole. When sufferers are constructive on a normal flu take a look at — a typical diagnostic that signifies human, swine, or fowl flu — clinics ought to probe extra deeply, Nuzzo mentioned.

The various is a wait-and-see strategy by which the nation responds solely after huge harm to lives or companies. This tack tends to depend on mass vaccination. But an effort analogous to Trump’s Operation Warp Speed shouldn’t be assured, and neither is rollout like that for the primary covid photographs, given an increase in vaccine skepticism amongst Republican lawmakers.

Change could as a substitute want to begin from the underside up — on dairy farms, nonetheless the commonest supply of human infections, mentioned Poulsen. He observed a shift in attitudes amongst farmers on the Dairy Expo: “They’re beginning to say, ‘How do I save my dairy for the subsequent era?’ They acknowledge how extreme that is, and that it’s not simply going away.”
