At this time, there have been no reported cases of local transmission of Zika in California. It is possible for some types of mosquitoes in California to carry the Zika virus and infect people here (known as "local transmission"), but the risk of this happening is very low. In California, Zika infections have been reported in people who were infected while traveling in areas outside of California with ongoing Zika transmission. There have also been reported cases of Zika transmission through sexual contact with an infected traveler. Cases of transmission from pregnant mothers to their developing babies have occurred in California in pregnant women who were infected while traveling in areas with Zika.
Pregnant women and their sexual partners should not travel to areas with risk of Zika transmission (including Mexico) during their pregnancy, and should know the risks that Zika poses to themselves, their family and their community.
Zika is a serious concern for a pregnant woman's developing baby, and infection during pregnancy can cause severe birth defects. Women and their sexual partners who must go to areas with Zika should prevent mosquito bites and avoid having unprotected sex during and after travel.
"Whether you work in a location with Zika, visit family who live in places with Zika or travel for leisure to places with Zika, you need to protect yourself." - CDPH Director and State Health Officer Dr. Karen Smith."
Couples planning pregnancy who are going to areas with Zika should talk with their doctor first and consider delaying pregnancy.
Travel to areas with Zika could include:
- Visiting family for an extended period of time
- Traveling outside of California for work
It is important to use insect repellent while in areas with reported active transmission of Zika, even if you are there for a short time. Mosquitoes that can carry the Zika virus are aggressive daytime biters.
