Zika is a disease caused by a virus that spreads to people mostly from the bites of a special type of mosquito,
Aedes mosquitoes. These mosquitoes can bite anytime, day or night. While
Aedes mosquitoes have been found in Los Angeles County, we have not found any mosquitoes infected with Zika virus. There is no vaccine or medicine for Zika. To date, all cases of Zika in Los Angeles County acquired their infection when traveling outside of California, mostly when traveling to Mexico or Central America (e.g., Guatemala, Nicaragua, El Salvador). Zika can also sometimes spread through unprotected sex. Most people infected with Zika have no signs of illness.
If they do, illness is usually mild with fever, joint pain, and rash and lasts about a week. However, if a pregnant woman becomes infected with Zika,
her baby can be born with birth defects.
