Hantaviruses belong to the Bunyaviridae family, which is comprised of Bunyavirus, Phlebovirus, Nairovirus, and Hantavirus. Euroasiatic Hantaviruses belong to two distinct subfamilies: Murinae (comprising Hantaan, Dobrava, and Seoul viruses), which are responsible for hemorrhagic fever with renal syndrome (HFRS), and Arvicolinae (comprising Puumala virus), responsible for nephropathia epidemica (NE) and HFRS. On the contrary, the New World Hantavirus belongs to the Sigmodontinae subfamily and includes the North American viruses: Sin Nombre, Monongahela; New York, Bayou, Black Creek Canal, and the South American, which comprise the Andes, Oran, Lechiguanas, Laguna Negra, Juquitiba; both groups are responsible for the hantavirus pulmonary syndrome (HPS).
