Spread / Exposure
Can Andes virus spread from rodents?
90-Second Answer
Last updated June 24, 2026
Short answer
Yes. Andes virus is associated with rodent hosts, and rodent exposure remains an important part of Hantavirus prevention guidance.
What it means
Public health guidance for Hantaviruses focuses heavily on avoiding contact with infected rodents, droppings, urine, saliva, and nesting material. Andes virus is different because person-to-person spread has also been documented, but rodents still matter.
What to know
Safe cleanup and rodent prevention guidance should come from official public health sources, especially if a home, cabin, storage area, or workplace has signs of rodent activity.
When to check official guidance
Use CDC prevention guidance for rodent-contaminated spaces and local public health guidance for local exposure concerns.
