From 24 to 30 July 2026, four new cases of human infection with avian influenza A(H9N2) virus were reported to WHO in the Western Pacific Region. All four cases were from China. The cases included a 72-year-old female from Jiangxi Province with symptom onset on 5 July 2026; a 12-year-old male from Jiangsu Province with symptom onset on 6 July 2026; a 3-year-old female from Gansu Province with symptom onset on 11 July 2026; and a 58-year-old female from Yunnan Province with symptom onset on 13 July 2026. The four cases reported were geographically distinct from each other. One case reported direct exposure to live-poultry, while three had potential exposure related to live-poultry stalls or wet market visits. Two cases with underlying chronic respiratory disease conditions were hospitalized and subsequently discharged. The remaining two cases experienced mild illness, were not hospitalized and had recovered at the time of reporting.

Since 2015, a total of 177 cases of human infection with avian influenza A(H9N2), including two deaths (both with underlying conditions), have been reported to WHO in the Western Pacific Region. Of these, 174 were reported from China, two were from Cambodia, and one was from Viet Nam.
