WHO Western Pacific has published Avian Influenza Weekly Update #1046 for 22 May 2026, continuing its regular regional surveillance of human and animal avian influenza activity.
The update appears on WHO's Western Pacific avian influenza surveillance page alongside the prior weekly report from 15 May 2026. The latest publication is part of the agency's ongoing series tracking developments across the region.
WHO Western Pacific did not provide additional details in the research material beyond the publication itself. The earlier weekly update, number 1045, reported one new human H9N2 case in the Western Pacific Region and no new human cases for several other avian influenza subtypes during that reporting period.
The new report keeps the surveillance record current as health officials continue to monitor avian influenza risks in the region.
