Health officials are reminding Hawaii residents to get rid of mosquito-breeding grounds as the state Department of Health is investigating four possible cases of the Zika virus, dengue fever and chikungunya on Oahu.
The Honolulu Star-Advertiser reports that the four cases were reported to the Department of Health on Thursday and all were acquired in Latin America or other Pacific Islands.
Department of Health Director Virginia Pressler says there have been no locally acquired mosquito-borne illnesses on Oahu. The four cases are no longer active.
Samples from the possible cases have been sent to the Centers for Disease Control and Prevention for identification.
Zika and dengue fever are spread by the same type of mosquito. To prevent mosquitoes form breeding, residents are encouraged to eliminate standing water from their homes.
