Hantavirus infection

Hantavirus is the name of a family of related viruses that have virtually a worldwide distribution. Anyone can become infected with hantavirus, but persons who have exposure to rodents or to rodent-infested areas are at highest risk of the infection. 

General information

Outbreaks of disease compatible with certain types of hantavirus infection have been described in Europe and Asia since the 1930's. However, in the United States, there were no reports of acute disease associated with hantavirus prior to 1993. In the spring of that year, an outbreak of severe respiratory disease caused by a newly recognized strain of hantavirus occurred in the southwestern USA. It is now apparent that illnesses due to this strain occurred before the 1993 outbreak, but were not recognized.
