Thailand reports 123% increase in dengue in 2024
The Thailand Bureau of Epidemiology has reported 26,527 total dengue cases since the beginning of the year, an 123 percent increase compared to the same period in 2023 (11,885).
In addition, the deaths reported risen from 13 last year to 22 this year to date.
The total cases include 19,131 dengue fever cases, 7,195 cases of dengue hemorrhagic fever and 201 cases of dengue shock syndrome.
The regions with the highest rates of sickness are: Central region, found mostly in people aged 15-24 years (1916 cases), 25-34 years (2148 cases), 10-14 years (1631 cases)
Northeastern region -10-14 years (907 cases), 15-24 years (816 cases), 7-9 year (407 cases).

Northern region, found mostly in people aged 15-24 years (689 cases), 10-14 years (518 cases), 25-34 years (491 cases) and Southern region, found mostly in people aged 15-24 years (1758 cases), 25-34 years (1316 cases), 10-14 years (1284 cases).
Dengue 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 (DEN1, DEN 2, DEN 3, DEN 4).

Dengue Fever (DF) – marked by an onset of sudden high fever, severe headache, pain behind the eyes, and pain in muscles and joints. Some may also have a rash and varying degree of bleeding from various parts of the body (including nose, mouth and gums or skin bruising).Dengue has a wide spectrum of infection outcome (asymptomatic to symptomatic). Symptomatic illness can vary from dengue fever (DF) to the more serious dengue hemorrhagic fever (DHF).
Dengue Hemorrhagic Fever (DHF) – is a more severe form, seen only in a small proportion of those infected. DHF is a stereotypic illness characterized by 3 phases; febrile phase with high continuous fever usually lasting for less than 7 days; critical phase (plasma leaking) lasting 1-2 days usually apparent when fever comes down, leading to shock if not detected and treated early; convalescence phase lasting 2-5 days with improvement of appetite, bradycardia (slow heart rate), convalescent rash (white patches in red background), often accompanied by generalized itching (more intense in palms and soles), and diuresis (increase urine output).
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, contribute to the development of shock, with resultant multiorgan failure.
