Hantaviruses are rodent-borne viruses causing clinical illness in humans of varying severity. There are several different hantaviruses, with a different geographical distribution and causing different clinical diseases. Each hantavirus is specific to a different rodent host. Transmission of the virus to humans occurs through the inhalation of infected rodent urine, droppings, or saliva.
