Top in ID: Undetected bird flu cases in veterinarians; CDC officers remain in positions

Fact checked byDrew Amorosi

Three bovine veterinarians had undetected H5N1 avian influenza infections despite no apparent contact with infected cows, suggesting that there may be U.S. states with unidentified positive cases of bird flu, research shows.

According to a study published in Morbidity and Mortality Weekly Report, all three veterinarians were based in the U.S. and reported no symptoms.

“Like previous studies, this study underscores the potential for missed avian influenza A(H5) infections in people who work with animals, but the data suggest these undetected infections are uncommon,” the CDC told Healio.“Increased testing of herds and bulk milking tanks can help monitor for additional A(H5) positive herds and help better protect bovine veterinary practitioners and other animal workers.”.

It was the top story in infectious disease last week.

In another top story, officers in the CDC’s Epidemic Intelligence Service are still employed and continuing to investigate public health concerns and outbreaks, despite reports that President Donald J. Trump and Elon Musk had fired at least half of the officers to reduce government spending.
