Individuals should always protect themselves against mosquitoes and mosquito bites island-wide; extra precaution should be taken in areas of risk.

The number of confirmed dengue fever cases in the state has risen to 79 according to new information released today (Thursday, Nov. 19, 2015) by the state Department of Health.

Of the confirmed cases, 68 are Hawaiʻi residents and 11 are visitors.  State health officials say 59 cases have been adults and 20 have been children.

As of today, a total of 120 reported potential cases have been excluded based on test results and/or not meeting case criteria, according to department reports.

The state also released a map showing potential areas of infection.  According to the map, which was updated on Nov. 18, the highest risk areas include Naʻalehu, Captain Cook and Kailua Kona.

Areas identified as moderate risk include Hilo and Pāhoa.  Four areas were identified as posing some risk including: Volcano, Waimea, Waikoloa Village and Hāwī.

Health officials say they continue to “routinely monitor for cases of imported dengue infection on all islands.”  The department will also continue efforts to have Vector Control units perform mosquito site assessments and abatement as needed.

Since the beginning of its current investigation on Hawaiʻi Island, one imported dengue fever case has been confirmed on Oʻahu. State officials say the case is not associated with the Hawaiʻi Island investigation.
