capitalized: a genus of single-stranded RNA viruses of the family Bunyaviridae that infect specific rodents as their natural hosts and that include some forms causing hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome in humans following exposure to the virus in airborne particles of rodent urine, feces, or saliva or directly by the bite of a rodent
: any virus (as the Hantaan virus) of the genus Hantavirus
Genus of viruses of the family Bunyaviridae that cause pneumonia and hemorrhagic fevers. Carried by rodents, they spread to humans directly or by inhalation but apparently are not transmitted from one person to another. An outbreak in the 1990s in the southwestern U.S. caused a mysterious, often fatal, flulike illness with rapid respiratory failure in previously healthy adults. The culprit was a hantavirus type carried by mice and not previously associated with human illness in the U.S.
