Hawaii Civil Defense Confirms Dengue Fever Cases in Waipio Valley

I just got off the phone with Hawaii County Civil Defense Administrator Chief Darryl Oliveira and he confirmed that the reason Civil Defense has closed access to Waipio Valley to only residents is because there have been confirmed cases of Dengue Fever in residents that live in the valley.  Some residents are part time residents and others live there all the time. (UPDATE – 6 confirmed cases relating to the area of Waipio Valley)

Department of Health Vector Control workers will begin working in the valley to eradicate mosquitoes, however, the valley is a unique area that does have a high density population of the mosquitoes that can can transmit dengue fever.

Center for Disease Control (CDC) will be back on the island this month and will be working in the Ho’okena Beach Park, Miloli’i area and now possibly Waipio Valley.

The county has not opened any of the closed parks and they do not have any date set on when the parks may open.  Civil Defense is aware of the impact this will have upon the residents of the valley, the taro farmers in the valley and as well as the tour companies that frequent the valley.

Hawaii County Civil Defense Closes Off Waipio Valley to Residents Only

This is a Dengue Fever information update for Wednesday January 13th at 2:30PM.

As a precaution, the Waipio Valley Access Road and valley area has been closed to all traffic effective 2:30 today and access will be limited to valley residents only. This restricted access will remain until further notice.

Waipio Hike

As of 1:00PM today the Department of Health reported 2 additional confirmed cases since yesterday. The total number of confirmed cases since the beginning of the outbreak remains at 215. These cases include 195 residents and 20 visitors.

Dengue is a virus that is transmitted from an infected person to a mosquito, which can then infect another person. Dengue fever cannot be spread directly from person to person. Of the 215 confirmed cases, 2 are recent and could be in the stage of their illness in which they can infect mosquitoes.

Symptoms of dengue include a high fever, intense headache and joint pain, and rash on the arms. If you suspect you may have dengue, contact your health care provider and remain indoors to prevent the possibility of being bitten and infecting mosquitoes.

The Department of Health is spraying and treating areas connected to confirmed cases to reduce mosquito populations. In addition, Civil Defense teams are inspecting areas of high mosquito presence reported by the community. If teams visit your home while you are away, they will leave a note – please follow the instructions on the note to contact the appropriate agency.

While these efforts lower risk by reducing mosquito populations, the most effective method to reduce the spread of dengue is for everyone to avoid and prevent mosquito bites. Fight The Bite by wearing clothing that minimizes exposed skin, using mosquito repellant, and avoiding activities in areas of high mosquito concentration during the early morning and late afternoon periods when mosquito activity is greatest.

For additional information on dengue and preventing the spread, go to health.hawaii.gov or call the Department of Health at 974-6001. Everyone’s help and assistance with this outbreak is much needed and appreciated.
