By making a surprising comeback amid a surge in respiratory diseases and surprise previously controlled diseases like tuberculosis, a new CDC report says that avian influenza is not detected in humans Provides further evidence of spreading into.
The latest Morbidity and mortality weekly reportsits publication It’s latethere are three cases of highly pathogenic avian influenza H5N1 in US veterinarians working with detailed cows, two cases It’s missing A clear source of exposure.
None of the veterinarians have experienced flu-like symptoms and no human-to-human spread has been detected yet. Researchers are concerned This ability can be just a few genetic variations.
Instead, these cases were detected through antibody tests from 150 veterinarians working in 46 US states in September, revealing that avian influenza is occurring beyond known infection zones. Ta. One vet who tested positive works with livestock in Georgia and South Carolina. Neither state has reported cases of avian flu in herds of dairy cows.
“What we lack is clearly an infection,” says Emory University virologist Sheema Rakdawara. I said Emily Antes New York Times.
Send of H5N1 through milk It has now been confirmed experimentally. In light of all this, health officials are urging all states to participate Milk Test Program.

Like fast-containment viruses, each lapse of containment increases the likelihood of testing random mutations and increases the chances of stumbling over what could spread between humans.
“If cases occur more frequently than they are detected in humans, there is a risk of missing out on small changes that allow the virus to spread far more easily to humans,” says Lauren, a researcher at the University of Nebraska infectious diseases. Soar I said NPR.
The first case of human H5N1 in Nevada was It was reported last weekbrings together a total of known human cases in the US Until 68. Nevada has also just detected a new strain of cow D1.1, which may be suitable for replication within cattle cells.
“The key part of stopping the spread of the virus is tracking them,” says Jody Guest, an epidemiologist at Emory University. I explained it After the death of the first human H5N1 in the United States was confirmed on January 6, 2025.
However, this difficult task becomes even more challenging due to the delay in information sharing due to the freeze in communications from several federal health agencies.
Delete CDC data has already been prompted Now contradictory fear About H5N1 From cat to human transmission.
KFF Health News Report Dairy workers have been infected with cats instead and are probably wearing work clothes, but this information should still be released. Data from these health agencies is not currently accessible elsewhere as they once did.
“The CDC is currently not reporting influenza data through the WHO global platform, Flute [and] Fluids, what they provide information [on] Epidemiologist Maria Van Kercouve for many years I said in the media brief.
“We’re communicating with them, but we’ve not heard anything.”
A case of cat-to-human transmission occurred Older bird flu strainsbut so far it’s not the H5N1. Two more pet cats After eating raw pet food in Oregon, I was euthanized with the disease.
Meanwhile, health officials will keep pets away from raw dairy products, prevent feeding pets from raw meat, avoid interacting with wildlife, and protecting animals when dealing with potentially infected livestock. It urges us all to wear.
Signs of infection in animals include fever, drowsiness, lack of coordination, circle movement, head tilt, and/or inability to stand or fly, and should be reported to local governments.
