Reported Cases of Hantavirus Disease

Hantavirus Infection in the United States

Hantavirus disease surveillance in the United States began in 1993 during an outbreak of severe respiratory illness in the Four Corners region. Hantavirus pulmonary syndrome (HPS) became a nationally notifiable disease in 1995 and is now reported through the Nationally Notifiable Disease Surveillance System (NNDSS) when fever is present in a patient with laboratory-confirmed evidence of hantavirus infection.

In 2014, the Council of State & Territorial Epidemiologists expanded the national reporting of laboratory confirmed hantavirus infections to include HPS and non-pulmonary hantavirus infection. Reporting of non-pulmonary hantavirus cases began in 2015.
