Update on CDC’s Avian Influenza A(H5N1) “Bird Flu” Response Activities

The CDC continues to address a multistate outbreak of avian influenza A(H5N1) virus in dairy cows across the U.S., collaborating with USDA, FDA, and state officials using a One Health approach. Currently, 42 dairy cattle herds in nine states have confirmed cases. While no new human cases have emerged since April 1, despite monitoring over 260 individuals, CDC remains vigilant.

Efforts include providing personal protective equipment (PPE) to farmworkers and conducting studies on the virus's severity and transmissibility using ferrets as a model. Results are expected in three weeks. This proactive approach underscores the importance of preparedness in safeguarding public health. Read more from the CDC here.
