Amid rising respiratory illnesses, a CDC report reveals undetected bird flu cases in US veterinarians. The spread, shown through antibody tests, indicates infections occurring beyond known zones. Experimental confirmation of H5N1 transmission through cow milk prompts officials to urge all states to join the national milk testing program.

A recent study by the Centers for Disease Control and Prevention (CDC) that was supposed to be made public weeks ago, but was withheld because President

A CDC study has found H5N1 bird flu antibodies in veterinarians who had no symptoms and no knowledge they had been working with infected livestock.

In leaked memos obtained by various media outlets, the Trump administration claimed that the pause at the CDC and other federal agencies would last until February 1. And this week, the MMWR finally did return, though it’s clear that not everything is back to normal.

After going quiet on bird flu, CDC scientists have published a report on its spread among veterinarians. The findings suggest a need for better surveillance.

The report is the latest evidence that the outbreak in dairy herds is spreading undetected in cows, and the spillover into people at highest risk of exposure is going unnoticed.

Three bovine veterinary practitioners had evidence prior infection with highly pathogenic H5N1 avian influenza despite having no apparent contact with infected cows, according to a study published in MMWR.

H5N1 bird flu is branching out. New data from the Centers for Disease Control and Prevention indicates that a second type of H5N1 has likely spread from dairy cows to humans.

With so much H5N1 circulating in the U.S., scientists worry we are a few mutations away from a potential human pandemic.
