Antibodies to La Crosse virus in eastern chipmunks in Indiana near an Aedes albopictus population.
Blood samples of 34 Eastern chipmunks trapped in the vicinity of an Aedes albopictus population near New Alsace, IN, were tested for neutralizing antibodies to La Crosse (LAC) virus and other California group viruses. Two samples were positive for LAC antibodies. Analysis of mosquito bloodmeals demonstrated that both Ae. albopictus and Ae. triseriatus from the site fed on chipmunks. This note documents the first record of LAC antibodies in sylvan rodents from Indiana, the presence of LAC virus in the vicinity of Ae. albopictus and that wild Ae. albopictus feed on Eastern chipmunks.
