Cambodia confirms human H5N1 avian flu case as H5N1 hits more Utah egg farms
Cambodia has reported a new human case of H5N1 avian flu in an infant, while the United States continues to see outbreaks in egg farms and cattle. Health officials are monitoring the situation closely as the virus spreads across both human and animal populations.
Why it matters
The ongoing spread of H5N1 in both humans and livestock poses a significant public health risk and threatens the stability of the agricultural supply chain.

The girl has been hospitalized and is receiving intensive care. So far no source of infection or exposure has been found, but the child’s close contacts are being given oseltamivir (Tamiflu) as a precaution.
Cambodia reported 19 human cases of H5N1 in 2025, eight of which were fatal. Most recent cases in Cambodia have involved a reassortant (2.3.2.1e) between an older H5N1 clade that has circulated in Cambodia since 2014 and the newer clade 2.3.4.4b virus that is circulating globally.
