WHAT IS THE ZIKA VIRUS?
Zika virus is a mosquito-borne virus that prior to 2015 occurred in Africa, Southeast Asia, and the Pacific Islands. However, in May 2015, the Pan American Health Organization (PAHO) issued an alert about the first confirmed Zika virus infections in Brazil. Since then Zika virus has been identified in several countries throughout South America, Central America, and the Caribbean, as well as states in Mexico. In the U.S., limited local transmission has been reported in Florida, and Texas. The U.S. territory of Puerto Rico has been significantly impacted. No locally-acquired cases of mosquito-transmitted Zika virus infection have been reported in San Diego County. All Zika cases reported locally have been travelers returning to San Diego from Zika-affected areas; this includes several sexually-transmitted cases and pregnancies reported to the U.S. Zika Pregnancy Registry.
