Hawaii’s first outbreak of dengue fever since 1943 has spread from Maui to Oahu, Kauai and the Big Island. As of Nov. 6 there were a total of 74 cases: 56 on Maui, principally in the east; 13 on Oahu; four on Kauai; and one on the Big Island. None of the cases has resulted in hospitalization. There is little risk to tourists staying in beach resorts in part because the mosquitoes that transmit the disease are seldom found on beaches.
