Short answer
Hantavirus is rare, but some Hantavirus illnesses can be severe and life-threatening.
What it means
CDC describes Hantavirus pulmonary syndrome as severe and potentially deadly. WHO also describes Hantavirus infections as ranging from mild to severe depending on the virus type, region, and disease pattern.
What to know
The right tone is neither panic nor dismissal. Everyday risk is low for most people, but possible exposure plus concerning symptoms should be taken seriously.
When to check official guidance
Check official guidance and contact a healthcare professional if symptoms develop after possible rodent exposure. Seek emergency care for breathing trouble.
