Virus classification
Group: Group V ((−)ssRNA)
Order: Unassigned
Family: Bunyaviridae
Genus: Hantavirus
Species: Bayou virus

Bayou virus (BAYV) is a species of hantavirus first identified in 1994 in Louisiana.[1][2] In 1996, the marsh rice rat was identified as the natural reservoir of the virus,[3] indicating the virus to be widespread throughout the Southeastern United States.[4] BAYV infection causes hantavirus pulmonary syndrome (HPS) and represents the second most common hantavirus in the United States behind the Sin Nombre virus.[5]
