Dengue Warning Reissue for Asia

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

Dengue fever (DF) – characterized by the sudden onset of high fever, severe headache, pain behind the eyes, and muscle and joint pain. Some may also have a rash and varying degrees of bleeding from different parts of the body (including the nose, mouth, gums, or skin bruising). Symptoms can vary from dengue fever (DF) to more severe dengue hemorrhagic fever (DHF).

Dengue hemorrhagic fever (DHF) – is a more severe condition, seen only in a small percentage of those infected. DHF is a typical disease characterized by three stages; febrile phase accompanied by severe persistent fever that usually lasts less than 7 days; The critical phase (plasma leak) lasting 1-2 days usually appears when the fever is reduced, leading to shock if not detected and treated early; The convalescent phase lasts 2 to 5 days with improved appetite, bradycardia (slow heart rate), convalescent rash (white spots in the red background), often accompanied by generalized pruritus (more severe in the palms and soles), and diuresis (increased output of urine).

Dengue shock syndrome (DSS) – shock syndrome is a serious complication of dengue infection and is associated with a high mortality rate. Acute dengue fever is caused by secondary infection with a different serotype of the virus. Increased vascular permeability, along with myocardial weakness and dehydration, contribute to shock, which leads to failure of many organs.
