The state Department of Health has responded to a single imported case of dengue on Hawaii island.

According to the department, vector control crews treated the affected person’s residence and adjacent properties on Saturday.

Health officials emphasized that there was no evidence of local transmission.

There have been no reported dengue cases attributed to local transmission since March.

“As the summer approaches and more travel is anticipated, the public is reminded that the most effective method to reduce the spread of dengue or other mosquito borne illnesses is for everyone to avoid and prevent mosquito bites,” the department said in a statement Saturday.

The public is encouraged to wear clothing that minimizes exposed skin, use mosquito repellent and avoid activities in areas of high mosquito concentration during the early morning and late afternoon periods, when mosquito activity is greatest.
