What is the Andes virus fatality rate?
90-Second Answer
Last updated June 24, 2026
Short answer
Fatality rates vary by outbreak and reporting source. CDC says Hantavirus pulmonary syndrome can be fatal in a substantial share of severe cases.
What it means
A single number can be misleading without the virus type, country, case definition, and care setting. CDC’s HPS guidance provides general severity context, while outbreak-specific Andes virus numbers should come from official reports or peer-reviewed sources.
What to know
Hantavirus Now should avoid inventing or averaging a fatality rate for Andes virus unless a source clearly supports the exact value and timeframe.
When to check official guidance
Check CDC, WHO, and official outbreak reports for source-supported numbers.
