HONOLULU (HawaiiNewsNow) - The state Health Department said it is investigating four cases of travel-related mosquito borne viruses on Oahu.
In a news release, the department said the cases include an individual who traveled to Latin America and returned to Hawaii ill. That person is being tested for dengue and Zika. There are other individuals who are being tested for dengue fever and chikungunya and have a history of travel to the Pacific Islands and Latin American.
The department said all of the individuals have recovered.
Officials said initial lab tests for the first individual were not conclusive, but further testing will be done by the Centers for Disease Control and Prevention. The state's vector control teams have been assessing residential and other areas in urban Honolulu and along the North Shore during the past week to determine if mosquito control measures are necessary.
The department said those measures would include eliminating mosquito breeding sites or spraying to reduce adult mosquito activity.
Dengue fever, Zika and ciungunya are all mosquito borne viruses that are spread when a sick person is bitten by a mosquito, which later bites another person. Evidence suggests that Zika can also be transmitted through unprotected sexual contact with someone who has been infected.
