Welcome to the State of California 

 Hantavirus Surveillance in California

The California Department of Public Health, Vector-Borne Disease Section (CDPH-VBDS) and its partner agencies collect and test rodents for rodent-borne diseases as part of its vector-borne disease surveillance program. CDPH-VBDS also collects information on hantavirus cardiopulmonary syndrome (HCPS) cases in California residents.

In California, the deer mouse (Peromyscus maniculatus) is the principal reservoir and vector (or carrier) of Sin Nombre virus (SNV), the specific hantavirus that causes HCPS in the western United States. This map displays county-level summaries of deer mice collections since 1975, hantavirus testing since 1975, and the distribution of 44 reported cases of HCPS in California residents by most likely county of exposure.

Notes:

Since rodent collection is not done uniformly throughout the state, absence of rodent collection or SNV-positive rodents in a given area may indicate lack of surveillance data; it does not mean that rodents or infected rodents are completely absent.

Data on this map represents rodents collected by the California Department of Public Health and local mosquito and vector control agencies. Locate your nearest vector control agency here.
