The Malaysian Ministry of Health has reported that the number of dengue cases reported in 2022 so far has more than doubled the numbers seen during the same period in 2021.
As of September 24, Malaysia had 42,084 cumulative cases compared to 19,423 cases for the same period in 2021, an increase of 22,661 cases (116.7%), while 24 deaths due to dengue complications were recorded compared to 13 deaths for the same period. 2021 period.
Of the 48 reported hotspots, 28 (58.3%) were localized in Selangor, 15 (31.3%) were localized in Sabah and five (5) (10.4%) were localized in WP Kuala Lumpur and Putrajaya.
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 2-5 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.
