Dengue fever is a viral infection transmitted by the bite of an infected mosquito. There are four closely related but antigenically different serotypes of the virus that can cause dengue fever (DEN1, DEN 2, DEN 3, DEN 4).

Dengue fever (DF) – marked by a sudden onset of high fever, severe headache, pain behind the eyes, and pain in the muscles and joints. Some may also experience a rash and varying degrees of bleeding from various parts of the body (including the nose, mouth and gums or bruising of the skin). Dengue fever has a wide range of infection outcomes (asymptomatic to symptomatic). Symptomatic disease can vary from dengue fever (DF) to the more severe dengue hemorrhagic fever (DHF).

Dengue hemorrhagic fever (DH) is a more severe form, seen only in a small proportion of infected people. DHF is a stereotypical disease characterized by 3 phases; febrile phase with continuous high fever that usually lasts less than 7 days; critical phase (plasma leak) lasting 1-2 days usually apparent when fever subsides, leading to shock if not detected and treated early; recovery phase lasting 2-5 days with improved appetite, bradycardia (slow heart rate), convalescent rash (white spots on a red background), often accompanied by generalized itching (more intense in the palms and soles of the feet) and diuresis (increased urine flow).

Dengue Shock Syndrome (DSS) – Shock syndrome is a dangerous complication of dengue infection and is associated with high mortality. Severe dengue occurs as a result of secondary infection with a different virus serotype. Increased vascular permeability, together with myocardial dysfunction and dehydration, contributes to the development of shock, leading to multiple organ failure.
