Bayou orthohantavirus

  (Redirected from Bayou virus)

Bayou orthohantavirus (BAYV) is a species of Orthohantavirus first identified in 1993 in Louisiana. [3] and later confirmed by other investigators. [4][5] In 1996, the marsh rice rat was identified as the natural reservoir of the virus,[6] indicating the virus to be widespread throughout the Southeastern United States.[7] BAYV infection causes hantavirus pulmonary syndrome (HPS) and represents the second most common hantavirus in the United States behind the Sin Nombre orthohantavirus.[8]
