摘要

A reassortant influenza A H1N2 virus was isolated from a returning traveller arriving at Nagoya International Airport, Japan from Indonesia in May, 2002. A Hemagglutination inhibition test revealed that the virus was similar to a vaccine strain of A/NewCaledonia/20/99. A phylogenetic analysis demonstrated that the virus forms a cluster with other influenza A H1N2 viruses isolated in other countries. The reassortment event was theoretically assumed to have occurred between the 1999/2000 and 2000/2001 influenza seasons. Neither A H1N2 nor A H3N1 virus was detected from 256 isolates of AH1 or 177 of AH3 influenza viruses isolated in Aichi Prefecture, Japan between the 1999/2000 and 2001/2002 influenza seasons. This finding suggests the importance of influenza surveillance at an airport quarantine office to detect promptly a novel influenza virus penetrating to Japan.
