Has Hantavirus been reported in California?
90-Second Answer
Last updated June 24, 2026
Short answer
Yes. California appears in CDC’s U.S. state-level Hantavirus case reporting.
What it means
CDC provides state-level reporting for U.S. Hantavirus disease. That means historical cases have been reported by state, but county-level public data is not provided on the CDC page.
What to know
A state-level report does not mean there is active risk everywhere in the state. Exposure risk depends on rodents, setting, and activity.
When to check official guidance
Check CDC case data and California public health agencies for state or local updates.
