Cepas de hantavirus y enfermedades que provocan

Andes virus is the dominant hantavirus in the Southern Cone of South America. It is the only hantavirus species with documented person-to-person transmission, which is why public health agencies place travel-linked clusters such as the MV Hondius event under heightened surveillance.

Huésped

Long-tailed pygmy rice rat (Oligoryzomys longicaudatus) and related Oligoryzomys species

Letalidad

30 to 50 percent in confirmed HPS cases

Sin Nombre virus is the most common hantavirus in North America and the cause of the original 1993 Four Corners hantavirus pulmonary syndrome outbreak. Deer mouse populations track precipitation cycles, so case counts spike after wet years.

Huésped

Deer mouse (Peromyscus maniculatus)

Letalidad

30 to 40 percent in confirmed HPS cases

Puumala virus causes a mild form of HFRS known as nephropathia epidemica (NE). Most cases are reported from Fennoscandia, where bank vole population peaks every three to four years drive outbreak years.

Huésped

Bank vole (Myodes glareolus)

Letalidad

Less than 1 percent

Hantaan virus is the prototype hantavirus and the cause of severe HFRS in East Asia. It remains a leading cause of hospitalised infectious nephritis in rural China and Korea.

Huésped

Striped field mouse (Apodemus agrarius)

Letalidad

5 to 15 percent

Seoul virus is the only hantavirus with a worldwide distribution because its rodent host follows global shipping routes. Recent clusters in pet rat keepers have prompted CDC and UKHSA advisories.

Huésped

Norway rat and black rat (Rattus norvegicus, Rattus rattus)

Letalidad

1 to 2 percent

Dobrava-Belgrade virus causes the most severe form of HFRS in Europe. The Apodemus flavicollis lineage is associated with higher case-fatality than Puumala or the Apodemus agrarius lineage.

Huésped

Yellow-necked mouse (Apodemus flavicollis) and striped field mouse (Apodemus agrarius)

Letalidad

Up to 12 percent for the Apodemus flavicollis (DOBV-Af) lineage
