Short answer
Andes virus is a type of Hantavirus found in South America. It can cause severe illness and is known for limited person-to-person spread in some settings.
What it means
Andes virus belongs to the Hantavirus family, but it should not be treated as identical to every Hantavirus headline. Public health sources describe it as a South American virus linked to rodent exposure, with reported person-to-person spread after close contact in some outbreaks.
What to know
The key difference is the virus type. Many Hantaviruses are mainly tied to rodents and are not known to spread between people. Andes virus is the main exception that public health sources call out, so source-backed updates should be clear about whether Andes virus is actually involved.
When to check official guidance
Check WHO, CDC, and involved public health agencies during any Andes virus-related event. For personal exposure or symptom concerns, speak with a healthcare professional.
