"Veterinarians who provide care for cattle were unknowingly infected last year."

"A scientific report from the Centers for Disease Control and Prevention published Thursday shows some veterinarians who provide care for cattle were unknowingly infected with the H5N1 avian influenza virus last year.

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.

Seema Lakdawala, a virologist at Emory University who studies transmission of influenza virus, said it is clear from the report and earlier research that “there are H5N1 cases we are missing.”

The report is one of three about bird flu that were scheduled to be published three weeks ago in the CDC’s Morbidity and Mortality Weekly Report (MMWR). But the scientific publication was abruptly suspended when the Trump administration instructed federal health agencies to pause all external communications on Jan. 21."
