From the CDC website:
The rodents shed the virus in their urine, droppings, and saliva. The virus is mainly transmitted to people when they breathe in air contaminated with the virus.
When fresh rodent urine, droppings, or nesting materials are stirred up, tiny droplets containing the virus get into the air. This process is known as "airborne transmission".
There are several other ways rodents may spread hantavirus to people:
If a rodent with the virus bites someone, the virus may be spread to that person, but this type of transmission is rare. Researchers believe that people may be able to get the virus if they touch something that has been contaminated with rodent urine, droppings, or saliva, and then touch their nose or mouth. Researchers also suspect people can become sick if they eat food contaminated by urine, droppings, or saliva from an infected rodent.
