The island of Maui is experiencing Hawaii’s first outbreak of dengue fever since 1943. So far 19 cases have been confirmed among residents of East Maui, including one part-time resident who carried the disease back to his Texas home. All cases have originated in East Maui, in the areas around Hana and Lower Nahiku. Checkpoints have been set up on the Hana and Pi’ilani Highways to provide visitors with information about the disease and its prevention. Dengue fever is a mosquito-borne viral disease that cannot be passed from human to human, but can spread from one human to another if both are bitten by the same mosquito. Symptoms include high fever, severe headaches, joint and muscle pain, nausea, vomiting and rash. The disease usually runs its course in ten days, but full recovery can take two to four weeks. There is no specific treatment or cure, and severe forms of the disease, dengue hemorrhagic fever or dengue shock syndrome, are rare but can be fatal. A sure preventive is to avoid being bitten by mosquitoes: wear clothing that covers the arms and legs, use insect repellent, and sleep under netting. The state health department has launched an extensive mosquito control campaign to contain the outbreak and eliminate the risk.
