The CDC issued a Health Alert Network advisory on May 12, 2026, urging clinicians to be aware of potential imported Andes virus cases from the cruise ship outbreak. While broad spread in the U.S. is 'extremely unlikely,' early symptoms can be confused with other illnesses. Several state health departments, including Arizona, California, Georgia, Texas, Virginia, New Jersey, and Maryland, are monitoring individuals.

Box-Kat reported on May 4, 2026, on hantavirus cases, highlighting the MV Hondius cruise ship outbreak where three people died and at least four were sickened by the Andes virus, which can spread human-to-human. The article also mentions the first positive hantavirus mouse reported in San Diego County, California, in January 2026, and New Mexico's first HPS case of 2025 (a 65-year-old woman from Santa Fe County). It notes that Arizona, New Mexico, and Colorado had the most confirmed cases between 2020-2025.

The CDC issued a Health Alert Network (HAN) advisory on May 8, 2026, to inform clinicians and health departments about the potential for imported cases of hantavirus disease in connection with the Andes virus outbreak aboard a cruise ship. While the risk of broad spread in the U.S. is considered 'extremely unlikely,' the agency noted that early symptoms can be easily confused with influenza or other viral illnesses. Several state health departments, including Arizona, California, Georgia, Texas, Virginia, New Jersey, and Maryland, have confirmed they are monitoring individuals in their respect

Hantavirus cases are on the rise in Arizona, with authorities reporting nine cases and three deaths "this year alone." This increase is attributed to factors like increased rodent population density and climate change driving rodents closer to human populations. Hantavirus Pulmonary Syndrome (HPS) has a high mortality rate of nearly 38%, and prevention focuses on avoiding contact with rodents and their droppings.

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.
