What is dengue fever? <br />Dengue fever is a viral illness spread by mosquitoes. The disease occurs mainly <br />in tropical Asia, Africa, the Caribbean and the South Pacific. It is most common <br />during the rainy season in areas infested with infected mosquitoes. Sometimes, <br />persons arriving from other countries may enter the United States with dengue fever and infect local <br />mosquitoes, as happened in Hawai‘i in 2001. <br /> <br />How do you get it? <br />The dengue virus is spread through the bite of infected Aedes mosquitoes. Dengue is not spread <br />directly from one person to another. <br /> <br />What are the symptoms of dengue fever? <br />The symptoms of dengue fever include sudden onset of fever, severe headaches, eye, joint, and <br />muscle pain, and rash. The rash typically appears on the hands, arms, legs and feet 3 to 4 days after <br />the fever begins. Minor bleeding problems can also occur. The symptoms usually go away completely <br />within 1 to 2 weeks. Sometimes, people with dengue fever have blood clotting problems. When this <br />happens, the illness is called dengue hemorrhagic fever. Dengue hemorrhagic fever is a very serious <br />illness with abnormal bleeding and very low blood pressure (shock). <br /> <br />When do symptoms start? <br />The symptoms usually start 5 to 6 days after being bitten by infected mosquitoes, but the onset can <br />range from 2 to 15 days. <br /> <br />What is the treatment for dengue fever? <br />There is no specific treatment for dengue fever. Bed rest and acetaminophen (Tylenol) to treat fever <br />and pain are recommended. Aspirin and NSAIDS (ibuprofen, naproxen) are not recommended as they <br />can make bleeding problems worse. There is currently no vaccine for dengue fever. <br /> <br />If you get dengue fever once, can you get it again? <br />Yes. There are four major types of dengue viruses. Having dengue fever with one type of dengue virus <br />will not protect you from the other three types. <br /> <br />How can you keep from getting it? <br />When traveling to areas that have dengue fever, try to avoid exposure to mosquitoes. Aedes <br />mosquitoes are usually most active in the early morning hours after daybreak, in the late afternoon <br />before dark, and any time during the day when indoors or in shady areas. <br /> <br />Use mosquito netting over beds, and screens on windows and doorways. <br /> <br />Use mosquito repellents and wear appropriate clothing such as long-sleeved shirts and long pants <br />that reduce exposure to mosquito bites. <br /> <br />Mosquitoes are drawn to dark colors; so if possible, wear white or light colored clothing when you <br />are likely to be exposed to biting mosquitoes. <br /> <br />For more information call the Department of Health (808) 974-6000 or visit www.health.hawaii.gov. <br /> <br />Kupuna News 4 Information and Assistance (808) 961-8777
