KFF Health News has a not-so-cheerful outlook on the US national health services in an article about livestock farms with a headline that starts “How America lost control of the bird flu” and ends “setting the stage for the next pandemic”:
Nearly a year into the first outbreak of the bird flu among cattle, the virus shows no sign of slowing. The U.S. government failed to eliminate the virus on dairy farms when it was confined to a handful of states, by quickly identifying infected cows and taking measures to keep their infections from spreading. Now at least 875 herds across 16 states have tested positive.
Experts say they have lost faith in the government’s ability to contain the outbreak.
“We are in a terrible situation and going into a worse situation,” said Angela Rasmussen, a virologist at the University of Saskatchewan in Canada. “I don’t know if the bird flu will become a pandemic, but if it does, we are screwed.”
To understand how the bird flu got out of hand, KFF Health News interviewed nearly 70 government officials, farmers and farmworkers, and researchers with expertise in virology, pandemics, veterinary medicine, and more.

More than 60 people in the U.S. have been infected, mainly by cows or poultry, but cases could skyrocket if the virus evolves to spread efficiently from person to person. And the recent news of a person critically ill in Louisiana with the bird flu shows that the virus can be dangerous.
Just a few mutations could allow the bird flu to spread between people. Because viruses mutate within human and animal bodies, each infection is like a pull of a slot machine lever.
“Even if there’s only a 5% chance of a bird flu pandemic happening, we’re talking about a pandemic that probably looks like 2020 or worse,” said Tom Peacock, a bird flu researcher at the Pirbright Institute in the United Kingdom, referring to covid. “The U.S. knows the risk but hasn’t done anything to slow this down,” he added.
Beyond the bird flu, the federal government’s handling of the outbreak reveals cracks in the U.S. health security system that would allow other risky new pathogens to take root. “This virus may not be the one that takes off,” said Maria Van Kerkhove, director of the emerging diseases group at the World Health Organization. “But this is a real fire exercise right now, and it demonstrates what needs to be improved.”

Studies in Colorado, Michigan, and Texas would later show that bird flu cases had gone under the radar. In one analysis, eight dairy workers who hadn’t been tested — 7% of those studied — had antibodies against the virus, a sign that they had been infected.
Missed cases made it impossible to determine how the virus jumped into people and whether it was growing more infectious or dangerous. “I have been distressed and depressed by the lack of epidemiologic data and the lack of surveillance,” said Nicole Lurie, an executive director at the international organization the Coalition for Epidemic Preparedness Innovations, who served as assistant secretary for preparedness and response in the Obama administration.
Citing “insufficient data,” the British government raised its assessment of the risk posed by the U.S. dairy outbreak in July from three to four on a six-tier scale.
Virologists around the world said they were flabbergasted by how poorly the United States was tracking the situation. “You are surrounded by highly pathogenic viruses in the wild and in farm animals,” said Marion Koopmans, head of virology at Erasmus Medical Center in the Netherlands. “If three months from now we are at the start of the pandemic, it is nobody’s surprise.”
