Dengue is an important mosquito-borne disease worldwide. It is caused by four dengue-associated viruses (DEN-1, DEN-2, DEN-3, and DEN-4) related to viruses that cause West Nile infection and yellow fever.

A person can become infected with each of these four viruses during their lifetime.

Dengue infection is transmitted primarily by the bite of certain types of mosquitoes Aedes aegyptibut also Aedes albopictusboth of which are located in Florida.

Dengue can be a painful and debilitating disease, but it is rarely fatal. Symptoms appear 3-14 days after the bite of an infected mosquito and include sudden onset of fever, severe headache, eye pain, muscle and joint pain (the illness is termed “breaking bone fever”), and bleeding. Gastrointestinal symptoms such as vomiting and diarrhea may also appear in some cases. Dengue symptoms usually last 4 to 7 days. The disease is often misdiagnosed because its symptoms are similar to the flu and other viruses.

Dengue hemorrhagic fever is a rare but more severe form of dengue infection that can be fatal if not recognized and treated with supportive care. The primary risk factor for hemorrhagic fever is previous infection with a different dengue serotype (ie infection with DENV-2 if you already have DENV-1 puts you at increased risk for hemorrhagic fever).
