Chikungunya is a virus transmitted to people by Aedes mosquitoes. There has been no locally acquired chikungunya in California but cases have been reported in travelers to areas where chikungunya is circulating. Travelers can protect themselves by preventing mosquito bites (See https://www.cdc.gov/chikungunya/prevention/index.html for tips).
Chikungunya is reportable in Orange County within one (1) working day of identification. To report a case, health care providers/facilities should call OCHCA Epidemiology at 714-834-8180 or fax records to 714-560-4050. In 2015, 24 cases of chikungunya were reported in Orange County (all in returning travelers), but in 2016 and 2017, two (2) cases were reported each year.
