The Pistillo virus belongs to the arenavirus genus, the ecological group of arboviruses, and the Tacaribe antigenic group. Its pathogenicity for humans has not yet been established.
The virus was first isolated from the field mouse Pistillus (Oryzomys) albigularis in Venezuela. It causes asymptomatic infection in rodents.
Arenaviruses are a family of RNA viruses that are transmitted by rodents and can cause severe disease in humans. These include Lassa fever, Junin fever, lymphocytic choriomeningitis viruses and some others.
In general, the Pistillo virus is of interest for studying the evolution and ecology of arenaviruses, but is not yet considered as a significant pathogen for humans. Further research will help to better characterize its properties and potential dangers.
