Short answer
Fatality rates vary by virus and disease type. CDC says 38% of people who develop respiratory symptoms of HPS may die from the disease.
What it means
A single fatality rate does not apply to every Hantavirus worldwide. CDC gives the 38% figure for Hantavirus pulmonary syndrome respiratory illness. WHO describes other Hantavirus disease patterns with different severity by region and virus type.
What to know
Fatality figures are serious, but they should be read with context: Hantavirus disease is rare, and risk depends on exposure, virus type, and clinical course.
When to check official guidance
Use CDC and WHO for fatality context, and consult a healthcare professional for personal medical concerns.
