Short answer

Hantavirus and COVID-19 can both involve fever and respiratory symptoms, but their usual transmission patterns, testing, public-health response, and exposure history differ. Hantaviruses are usually linked to rodent exposure; Andes virus can also involve close contact with a sick person.

Testing and care

Do not self-diagnose based on a comparison chart. Clinicians and public-health laboratories determine appropriate testing based on symptoms, timing, and exposure history.

Frequently asked questions

Can a symptom list distinguish hantavirus from COVID?
