Bird flu is once again making its way into headlines. Cambodia is currently tracking the H5N1 bird flu in a human girl, while China has seen an uptick in cases of the H9N2 strain of the virus.
Last week, a 3-year-old girl from Kampong Speu province was sickened. She received intensive care for her H5N1 infection. A statement from the Cambodia Ministry of Health said birds in the patient’s home and in neighboring houses had been sick and dying for roughly a week when the child became ill. Now, the CMH is tracking the disease in a 14-year-old girl. She is currently hospitalized for her infection, with no information on where she’d been infected or exposed to the virus, according to CIDRAP, the University of Minnesota’s Center for Infectious Disease Research and Policy.
Are we on the cusp of seeing human-to-human bird flu transmission?

Also in this week’s CHP (Center for Health Protection) update, officials note four H9N2 cases in mainland China that were retrospectively recorded. The cases include a person in Guangdong province who had an illness onset in February 2025. In that same month, two ill people in the Guangxi Zhuang Autonomous region were also reported, as was one case-patient in the Tianjin municipality.
