Zika Information


Zika virus is transmitted to humans primarily through the bite of an infected Aedes aegypti mosquito (yellow fever mosquito) or Aedes albopictus mosquito (Asian tiger mosquito). These mosquitoes are not native to California. However, since 2011 they have been detected in several California counties. The Aedes mosquito has not been detected in San Luis Obispo County, although it is present in 22 other California counties, including Santa Barbara County and Kern County. There has been no local mosquito bite transmission of Zika virus in California to date, and the risk in our state remains low. 

Zika virus infections in California have been documented only in people who were infected while traveling outside the United States or through sexual contact with an infected traveler. More information specific to California is available from the California Department of Public Health Zika page.
