Zika Virus Information

About Zika 

Zika is a disease caused by the Zika virus. Symptoms of Zika include fever, rash, joint pain, and conjunctivitis (red eyes). Zika virus is transmitted through a bite from a Zika-infected mosquito to a person. Only about one in five people who are infected with Zika virus will experience symptoms, and the illness is usually mild and does not require hospitalization. There is currently no vaccine or medicine for Zika.

The type of mosquitoes that are able to transmit Zika virus are Aedes aegypti (the yellow fever mosquito) and Aedes albopictus (the Asian tiger mosquito). These mosquitoes are small with black and white striped legs, and they bite during daytime, especially around dawn and dusk. At this time, these mosquitoes have not been detected in Santa Clara County. For more information about the Aedes mosquitoes, or if you think you might have seen one in your community, please visit Santa Clara County Vector Control District​ and view a video on how to avoid mosquito bites (English / Spanish).

Zika & Pregnancy 

The main reason that Zika is concerning is that it can cause birth defects. Women​ who are infected with Zika virus during their pregnancy are at increased risk for having babies with birth defects such as microcephaly (abnormally small head). Because of this increased risk, the CDC advises pregnant women to postpone travel to areas with local Zika virus transmissionFor more information about Zika and pregnancy, please see information below:

Zika Sexual Transmission​  
Both men and women can transmit Zika virus to their sexual partners. Therefore, the CDC recommends that men who live or have traveled to a Zika-affected area should abstain from sex or use condoms if their partner is pregnant for the entire duration of their partner’s pregnancy:
