Common questions about hantavirus.

In the Americas, no. Hantavirus Pulmonary Syndrome is not transmitted between people. The one exception is the Andes virus in South America, which has been linked to rare cases of human-to-human transmission.

No FDA-approved vaccine exists. Inactivated vaccines are used in China and South Korea but are not widely available elsewhere. Prevention through rodent control remains the only reliable defense.

Rodent infestations can occur in any enclosed environment, including ships. The MV Hondius cruise ship investigation in 2026 highlighted that confined ventilation systems on ships can amplify hantavirus exposure when rodent contamination is present. It is not spread between passengers.

Two to three days at normal room temperature. Ultraviolet light, standard household disinfectants, and temperatures above 37°C all deactivate it effectively.

Do not sweep or vacuum. This aerosolizes the virus. Ventilate the area, spray droppings with a 1:10 bleach-to-water solution, wait five minutes, then clean with gloves and dispose of materials in sealed bags.

People who live or work in rural areas with active rodent populations. Opening unused cabins, cleaning barns, or disturbing rodent habitats are the most common exposure scenarios. There is no age or gender predisposition.

There is no specific antiviral treatment. Early recognition and intensive care, specifically mechanical ventilation and careful fluid management, are critical. The fatality rate for HPS is approximately 36%, which underscores the importance of seeking immediate medical attention.

From symptom onset, HPS can progress to respiratory failure within 4 to 10 days if untreated. The early phase resembles flu, making early diagnosis challenging. Seeking medical care at the first sign of respiratory difficulty is critical.

Confirmed HPS cases are rare in the UK and France, though the Puumala virus circulates in parts of continental Europe. In India, the Seoul virus carried by urban rats is a concern. All three countries have increased surveillance following 2026 outbreak news.

The Andes virus is a hantavirus strain found in Argentina, Chile, and parts of South America. It is the only known hantavirus capable of limited person-to-person transmission, making it distinct from other strains.
