Abstract excerpt

Influenza A(H3N2) remains a significant public health threat due to its rapid antigenic drift, which often compromises vaccine effectiveness. This study characterized the molecular and epidemiological profile of hemagglutinin (HA) variants circulating in Western Mexico throughout 2022. Among 476 positive cases, A(H3N2) was the predominant subtype (88%), with infection peaks during epidemiological weeks (EW) 1,...
