Dengue Fever Update – 92 Confirmed Cases, 143 Potential Cases Excluded

The Hawaii Department of Health (HDOH) is investigating a cluster of locally-acquired cases of dengue fever on Hawaii Island. Dengue is not endemic to 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.

HDOH continues to routinely monitor for cases of imported dengue infection on ALL islands and will continue to have Vector Control perform mosquito site assessments and abatement as needed.  Since the beginning of our current investigation on Hawaii island, one imported dengue fever case has been confirmed (on Oahu). This case is not associated with the Hawaii island investigation.
