Sin Nombre orthohantavirus

Sin Nombre orthohantavirus (SNV) (from Spanish, meaning "without a name"), a member of the genus Orthohantavirus, is the prototypical etiologic agent of hantavirus cardiopulmonary syndrome (HCPS).

Discovered in 1993 near the Cañon de la Muerte on the Navajo Reservation, it was originally named the Muerto Canyon hantavirus, in keeping with the convention for naming new pathogens. However, the Navajo Nation objected to the name in 1994. It was also near the Four Corners point in the United States, so the virologists then tried naming it the "Four Corners virus". The name was changed after local residents raised objections. In frustration, the virologists changed it to Sin Nombre, meaning "without a name" in Spanish.
