Abstract

Highlight

- Dengue fever, or dengue infection, is a mosquito-borne disease transmitted by the Aedes mosquito. As of August 19, 2025, Thailand has reported a cumulative total of 38,687 dengue cases (incidence rate: 59.60 per 100,000 population) and 37 deaths (case fatality rate: 0.10%).

- In 2025, the number of reported cases remains lower than both the five-year median (2020–2024) and the previous year (2024). However, as the country is currently in the seasonal outbreak period, case numbers are expected to increase, particularly in areas with continuous rainfall.

- It is therefore crucial to closely monitor and track the situation, and to strengthen prevention and control measures, especially in areas experiencing outbreaks and deaths, in order to mitigate the severity of the outbreak and reduce fatalities.
