In its acute form, dengue is characterized by flu-like symptoms including severe pain in the head, eyes, muscles and joints. The incidence of both forms of dengue infection has recently been increasing, as expanding urbanization enlarges the regions inhabited by the Aedes mosquito vector. Mosquitoes capable of transmitting this disease are also found within the United States.
Dengue fever is more prevalent when it has been raining constantly.
Victims typically experience a sudden high fever, headache and intense body pain about 5-8 days after being bitten by an infected mosquito. A measles-like rash near day 3 of the fever can help distinguish dengue from other tropical illnesses. The acute illness usually concludes on its own after about a week, but fatigue and depression can last for weeks or months in some cases. There is no vaccine against dengue. The best protection is to use repellents.
