Dengue has been called the most important mosquito-transmitted viral disease in terms of morbidity. Dengue fever is a epidemic, acute febrile syndrome occurring in tropical regions. In a small proportion of cases, the virus causes increased vascular permeability that leads to a bleeding or disseminated intravascular coagulation (DIC) known as dengue hemorrhagic fever (DHF). Secondly infection by a different dengue virus serotype has been confirmed as an important risk factor for the development of DHF.
In 25-35% of DHF cases, the patient develops shock, known as the dengue shock syndrome (DSS).
Worldwide, children younger who are younger than 15 years make up 95% of DHF cases.In the Americas, however, DHF occurs in adults and children.
Dengue fever is not contagious through person-to-person contact.
Complications
Complications are rare but may include the following:
- Brain damage from prolonged shock or intracranial hemorrhage
- Myocarditis
- Encephalopathy
Liver failure
