Hantavirus Pulmonary Syndrome is a rare but serious lung disease spread by deer, mice and other wild rodents. Hantavirus is found in the saliva, urine and droppings of infected rodents.

What causes Hantavirus?

People can get Hantavirus when they breathe in tiny particles of fresh saliva, urine, droppings or nesting materials that are infected with the virus. For example, you could get Hantavirus if you sweep out a garage that has infected mice nesting in it. Sweeping stirs up tiny particles of the infected droppings, urine or saliva, and makes them float in the air. When you breathe in these tiny infected particles, the virus enters your lungs and you can get sick.

Can you catch Hantavirus from another person?

No. Hantavirus Pulmonary Syndrome is not spread from person to person. You can’t catch it by touching or being around someone who has it.

Signs and Symptoms

Early symptoms of Hantavirus Pulmonary Syndrome are similar to the flu. Symptoms usually appear about two to three weeks after being exposed to the virus.



The earlier Hantavirus infection is treated, the better the chances are for recovery.


Who Is At Risk?

People who are often near places where rodents live have a higher risk of infection.


Reduce Your Risk

The first step in reducing your risk of Hantavirus infection is to prevent rodents from getting into the places you live, work and play.
