HDOH investigates cluster of dengue fever on the Big Island

The Hawaii Department of Health (HDOH) is currently investigating a cluster of locally-acquired cases of dengue fever on the Big Island of Hawaii.

Dengue is not endemic in Hawaii, however it is intermittently imported from endemic areas by infected travelers. This is the first cluster of locally-acquired dengue fever since the 2011 outbreak on Oahu.
