Hantavirus Pulmonary Syndrome (HPS) is a potentially fatal respiratory infection spread by rodents that carry hantaviruses. While several types of rodents are capable of transmitting hantaviruses to humans, the deer mouse is the main culprit in the U.S.

Aerosolization of the virus due to airborne particles of contaminated urine, feces, or saliva from infected rodents is the primary source of infection in humans. Most cases of hantavirus are contracted in the spring and summer months while many people are either camping in cabins or cleaning up their homes, yards, and sheds.

Hantavirus infection is characteristically an influenza-like illness, and while some symptoms overlap, there are a few hallmark differences. While both illnesses can become fatal if left untreated, the mortality rate of the flu is roughly 0.1 percent, while the mortality rate of hantavirus is an alarming 38 percent of those infected.

What's more, while there is a vaccine that can help ward off the flu as well as an influenza active antiviral therapy to treat it, there is no known effective treatment or vaccine for hantavirus, making rodent prevention and control both inside the home and out crucial to prevent the spread of hantavirus.

Wear surgical gloves and masks when cleaning areas potentially contaminated by rodents. Wash hands after cleaning and always avoid touching your face, eyes, and mouth while working. Do not dry sweep or vacuum where there is evidence or suspicion of a rodent infestation, as this may increase the risk of producing airborne particles. If hantavirus is present and aerosolized, the risk of infection is much greater.

Contact a licensed pest control professional to handle the cleanup if you see evidence of rodent infestation or need disposal of any rodents on your property to reduce potential exposure to the virus.

If you or a loved one develop symptoms of hantavirus, seek medical attention immediately.
