Hantaviruses

Abstract

Hantaviruses comprise a genus of the Bunyaviridae family and naturally infect wild rodents without causing clinical symptoms. When acquired by inhalation of aerosolized rodent excreta, hantaviruses can cause life‐threatening diseases in humans, such as haemorrhagic fever with renal syndrome in Asia and Europe and hantavirus pulmonary syndrome in the Americas.

Keywords: Hantaviruses; Bunyaviridae; rodent‐borne; haemorrhagic fever with renal syndrome; HFRS; hantavirus pulmonary syndrome; HPS; molecular biology; epidemiology
