Prior to 2015, Zika outbreaks have been reported in areas of Africa, Southeast Asia, and the Pacific Islands. More recently, they have been reported in Brazil and elsewhere in Latin America. Outbreaks have also been reported in the Pacific Islands. For up-to-date details, go to this link.
To date, however, there have been no locally transmitted cases of Zika in Hawaii (meaning cases caught by a mosquito in Hawaii). Occasionally, visitors to Hawaii or Hawaii residents returning to the state have been infected with Zika from mosquitoes elsewhere. The Department of Health investigates each reported case as soon as we hear about it to prevent Zika from spreading beyond these imported cases.
