Zika Virus
Zika is a disease caused by a virus that is mostly spread through the bite of a special type of mosquito, the Aedes mosquito. While Aedes mosquitoes have been found in Los Angeles County, we have not found any mosquitoes infected with Zika virus. To date, all cases of Zika in Los Angeles County acquired their infection when traveling outside of California. Information on number of Zika cases detected in Los Angeles County is available in this report.

Travelers may be at risk of infections spread through mosquito bites while traveling outside Los Angeles County. Review destination-specific risk and prevention measures prior to travel here.

Locations where Zika has been detected is available  HERE.

Please note: Given global decline in the number of Zika cases, the Centers for Disease Control and Prevention (CDC) issued a guidance statement in November 2019 that no longer recommends serological testing for Zika even in symptomatic returning travelers. This is due to the unreliability and cross-reactivity of the Zika antibody tests. If suspected, Zika nucleic acid amplification testing (NAAT) should be conducted in conjunction with testing for dengue, which is occurring more commonly around the world.
