90-Second Answer
Last updated June 24, 2026
Short answer
Yes, limited person-to-person spread of Andes virus has been documented, usually after close and prolonged contact.
What it means
WHO identifies Andes virus as the Hantavirus associated with person-to-person transmission. CDC describes the risk around close contact with someone who is sick, such as living with, caring for, sharing a bed with, kissing, or having sexual contact with an infected person.
What to know
Close contact, timing, symptoms, and official contact tracing matter. This is not the same as saying brief casual contact automatically creates the same level of risk.
When to check official guidance
Check WHO, CDC, and local health agencies if an Andes virus exposure is being investigated.
