The US Centers for Disease Control and Prevention is urging hospitals to accelerate advanced testing of people they suspect may have bird flu.

Bird flu is a disease caused by avian influenza A viruses, according to the CDC. The virus mostly spreads between birds and dairy cows, but there have been 67 human cases of bird flu nationwide and one death tied to the infection since 2024, CDC records show.

Due to ongoing sporadic H5N1 avian flu infections and brisk levels of seasonal flu activity, the US Centers for Disease Control and Prevention (CDC) today urged healthcare providers to subtype all influenza A specimens in hospitalized patients, especially those in the intensive care unit (ICU), as soon as possible.

CDC officials say they extended the guidance now because they are seeing more H5N1 patients whose illness they cannot track back to an infected bird or cow.
