Basics
Is Hantavirus contagious?
90-Second Answer
Last updated June 24, 2026
Short answer
Most Hantaviruses are not known to spread from person to person. The main exposure risk is usually rodents.
What it means
CDC says Hantaviruses are spread mainly by rodents and are not spread person to person. WHO notes an important exception: Andes virus, found in South America, has documented limited person-to-person spread.
What to know
The specific virus matters. A general Hantavirus headline does not automatically mean person-to-person spread is expected.
When to check official guidance
Check WHO, CDC, and the public health agencies involved during an outbreak or after a known exposure.
