In 2025, Taiwan implemented paired sera surveillance among occupational contacts of avian influenza viruses (AIVs). Of 122 contacts analyzed, 117 (95.9%) remained asymptomatic with high personal protective equipment compliance (91.8%). No seroconversion was detected against AIV A(H5N2) clade 2.3.4.4b. These findings suggest a low risk of human infection despite persistent poultry outbreaks, provide timely serological evidence during the ongoing outbreak, and demonstrate the effectiveness of Taiwan's integrated human-animal surveillance in early risk characterization.
Keywords: Taiwan; avian influenza; communicable diseases, emerging; public health surveillance; serology.
