The government warns residents in the southern region to be cautious of dengue fever, as stagnant floodwaters have caused cases to surge by 1.7 times, with a cumulative death toll of 47, mostly elderly. Authorities have urged public health workers and village health volunteers to inform the public and raise awareness to prepare for the outbreak.
On 15 November 2026, Ms. Ploytale Laksamee Sangchan, Deputy Spokesperson of the Prime Minister's Office, revealed that according to epidemiology data from the Department of Disease Control, dengue fever cases in Thailand in 2026 are lower than in 2025. As of 7 November 2026, there have been 34,875 dengue cases, mostly among school-age and working-age groups, with 47 deaths primarily in the elderly.
Ms. Ploytale added that currently the highest number of dengue cases are in health areas 11 and 12 in the southern region. Area 11 alone has about 1.7 times the national average number of cases, likely due to continuous rainfall. Looking at the whole year, the peak month was August with around 1,450 cases, which is still lower than August 2025, when approximately 2,700 cases were reported.
The government expresses concern for southern residents, as the flooding situation has led to increased dengue fever cases by creating more breeding grounds for Aedes mosquito larvae, raising transmission risk. The government has instructed health personnel and village health volunteers to alert the public to be aware and prepare to prevent further increases in dengue cases.
