Short answer
Andes virus is a type of Hantavirus found in South America. It can cause severe illness and is notable because limited person-to-person spread has been documented.
What it means
WHO describes Andes virus as part of the Hantavirus family and says it is found in South America, especially Argentina and Chile. Like other Hantaviruses, it is linked to rodents. What makes Andes virus different is that public health sources have documented limited spread between people, usually after close and prolonged contact.
What to know
Andes virus is not the same as every Hantavirus headline. Most Hantaviruses are mainly tied to rodent exposure and are not known to spread between people. Andes virus is the main exception public health sources point to, which is why source-backed reporting should name the virus type when that information is available.
When to check official guidance
Check WHO, CDC, and local public health agencies during any Andes virus-related event. For personal exposure or symptom concerns, speak with a healthcare professional.
