Short answer
Yes. Hantavirus disease is uncommon, especially compared with many respiratory and seasonal infections.
What it means
CDC’s public U.S. surveillance page tracks laboratory-confirmed Hantavirus disease since surveillance began in 1993. The total number of reported cases is small compared with common infectious diseases.
What to know
Rare does not mean impossible. Most risk reduction guidance focuses on specific exposure settings, especially rodent-contaminated areas.
When to check official guidance
Use CDC case data for national context and state or local public health departments for local questions.
