Frequently Asked Questions About Hantavirus:
Does hantavirus occur in the United States?
Yes. Hantavirus is present in the United States, though health officials most often identify cases in rural environment more than typical residential neighborhoods. Approximately 94% of reported U.S. cases occur west of the Mississippi River, with the highest case counts reported in Colorado, New Mexico, and Arizona.
Is hantavirus contagious between people?
In North America, hantaviruses are not known to spread from person to person. Most hantavirus strains do not transmit between people. The only documented exception involves the Andes strain in South America, where extremely rare person-to-person transmission has occurred.
What warning signs may appear early with hantavirus infection?
Early symptoms are often broad and can resemble other illnesses. Initial signs may include:
- Fatigue
- Muscle aches
- Fever
- Headaches
- Dizziness
- Chills
- Abdominal distress

How does someone become infected with hantavirus from rodents?
Hantavirus from rodents most commonly occurs when a person inhales microscopic airborne particles contaminated with infected rodent urine, droppings, or saliva.
A possible exposure scenario could involve cleaning a remote cabin or enclosed structure where wild rodents had been active, particularly without using recommended protective precautions.
Does seeing mice in my home mean I’m at risk for hantavirus?
Usually, no. Hantavirus is maintained primarily in wild rodent populations, which do not commonly become household pests.
Even in regions considered higher risk, house mice—the rodents most commonly seen inside homes, garages, and basements—are not the usual carriers associated with hantavirus transmission.
Is hantavirus something most homeowners need to worry about?
No. Hantavirus is highly unlikely to become a widespread pandemic threat similar to COVID-19.
Because nearly all hantavirus strains are not transmitted person to person, broad community spread is considered nearly impossible. Even in elevated-risk regions, the likelihood of individual infection remains extremely low.
What’s the safest way to clean up after rodent activity?
Proper personal protection is essential when cleaning up after rodents to reduce potential health risks.
The Centers for Disease Control and Prevention (CDC) provides detailed step-by-step cleanup recommendations, including protective measures and disinfection guidance:
