Bayou virus (BAYV) is a species of Orthohantavirus comprising enveloped and spherical viruses. It was first identified in 1993 in Louisiana and later confirmed by other investigators. BAYV was recognized as a distinct form of hantavirus disease, now known as hantavirus pulmonary syndrome (HPS). It now represents the second most common hantavirus in the United States behind the Sin Nombre virus. In 1996, the marsh rice rat, which is seen in marshes in the southeast and mountain streams in the northeast, was identified as the natural reservoir of the virus. Although the virus was first identified in Louisiana, it is widespread throughout the Southeastern United States. This hantavirus disease is known as a severe and sometimes fatal respiratory disease, and HPS has a case-rate fatality of almost 50%.
