Following a CDC study showing bird flu exposure among dairy workers, health officials recommend increased testing and preventative measures for farmworkers, even if they show no symptoms, to prevent virus spread and mutation.

In 2024, a total of 46 people in the U.S. have been diagnosed with the bird flu after being exposed to either an infected cow or bird.
