A recent Newsweek article highlights CDC data showing over 300 hantavirus deaths in the U.S. since surveillance began in 1993, out of 890 reported cases through 2023. The Sin Nombre virus, carried by deer mice, is responsible for most U.S. cases, primarily in western states like New Mexico, Colorado, Arizona, California, and Washington. The article provides context on the disease's history and geographical distribution in the U.S., distinct from the Andes strain causing the recent cruise ship outbreak.

As of the end of 2023, 890 laboratory-confirmed cases of hantavirus disease have been reported in the United States since surveillance began in 1993. Hantavirus Pulmonary Syndrome (HPS) became a nationally notifiable disease in 1995. The data shows distribution by state, with the Four Corners region (Arizona, Colorado, New Mexico, and Utah) being a historically significant area for outbreaks. The Council of State & Territorial Epidemiologists expanded national reporting in 2014 to include both HPS and non-pulmonary hantavirus infections.

A CDC map reveals that over 300 individuals have died from hantavirus in the United States since surveillance commenced in 1993, out of a total of 890 reported cases. The Sin Nombre virus is the most common strain in the US, typically spread by deer mice. In contrast, the Andes strain, prevalent in South America and linked to the recent cruise ship outbreak, is the only hantavirus known to allow limited human-to-human transmission. States with the highest numbers of cases and deaths include New Mexico, Colorado, Arizona, California, and Washington.
