Officials scramble to stop dengue excerpt: "The U.S. Centers for Disease Control has confirmed 39 cases of dengue fever on Maui and one on Kauai, the state Health Department said yesterday. Nine other cases tested positive on preliminary screening tests, and 165 reports of illness are being investigated on the four major islands." "When you haven't had a disease in the state for 50 years, it's easy to let that fall from consideration," state epidemiologist Paul Effler said. Hawaii now has 28 known imported cases, he said, with 24 occurring in July and August. The normal annual average is three."
