California Hantavirus Map

California public health sources emphasize deer mouse exposure, safe cleanup, and workplace settings such as parks, campgrounds, maintenance areas, cabins, and other enclosed spaces.

Key Points

CDPH states that wild rodents, including deer mice, are common in many parts of California.

CDPH links to an official interactive story map and a county-of-exposure PDF through 2024.

What the California layer means

The California marker means official California hantavirus surveillance and prevention resources are available. It does not mean the site is publishing a live California case layer.

County of exposure is useful epidemiologic context, but it is not the same as exact household or recreation-site risk.

Workplace and recreation context

CDPH occupational health guidance highlights people whose work can disturb rodent-contaminated enclosed spaces.

For site-specific workplace concerns, follow employer safety procedures and contact public health or occupational safety authorities.
