Molecular analysis of influenza A(H3N2) in a remote tropical island during 2014-2019 to identify the frequency of introduction and local circulation
In our study population, A(H3N2) circulation resulted from multiple introduction events, followed by local circulation lasting less than 3 months, with occasional long-term persistence. Our study indicates that tropical regions may contribute to maintaining globally circulating strains but may not be a source of antigenic variants.
