Short answer
Andes virus is linked mainly to rodent exposure, but limited person-to-person spread has also been documented after close contact.
What it means
Like other Hantaviruses, Andes virus can be connected to contact with infected rodents or contaminated materials. The added concern is that public health literature has documented limited spread between people, usually in close-contact situations.
What to know
This is why Andes virus reporting should be precise. Rodent exposure and close-contact monitoring are different public health questions, and both should be handled with source-backed wording.
When to check official guidance
Use WHO, CDC, and involved public health agencies for outbreak-specific instructions. This site does not provide medical advice.
