Hantavirus is transmitted to humans mainly through inhalation of aerosolized virus from rodent urine, droppings, or saliva. When rodent-contaminated dust is disturbed—such as during cleaning or sweeping in enclosed spaces—the tiny particles can be inhaled and initiate infection. This inhalation route is the primary way people become infected.

Other potential ideas listed don’t fit hantavirus transmission. A direct bite from a dog is not a known transmission route for this virus. Contaminated water isn’t a typical pathway for hantavirus spread, and sunlight exposure has no role in transmitting the virus.

Understanding this helps emphasize practical prevention: avoid disturbing rodent harborages, dampen dust before cleaning, wear appropriate protective gear, and control rodent access to spaces to minimize aerosolization of contaminated particles.
