Thai dengue toll at 47 as southern Region 11 reports 1.7 times national level
Thailand recorded 34,875 dengue cases and 47 deaths through November 7, with health workers urged to alert flood-affected southern communities.
- Thailand has recorded 47 deaths and 34,875 dengue cases nationwide as of November 7.
- Southern Health Region 11 is a key area of concern, reporting a dengue rate approximately 1.7 times the national level.
- Authorities are concerned that flooding and standing water in the south are creating more breeding grounds for mosquitoes, increasing infection risk.
- Despite the southern outbreak, the cumulative number of dengue cases nationwide in 2026 is lower than in the previous year.
The Thai government has instructed health workers and village health volunteers to strengthen dengue awareness in flood-affected southern Thailand, amid concerns that standing water could create more mosquito breeding grounds and increase the risk of infection.
Deputy government spokeswoman Ploytalay Laksameesangchan said on Sunday (November 15, 2026) that southern health regions were reporting the highest numbers of dengue cases, although the cumulative national total remained below the previous year’s level.
Citing the Department of Disease Control’s Division of Epidemiology, she reported 34,875 dengue cases and 47 deaths nationwide through November 7. Most patients were of school or working age, while deaths were concentrated among older adults.
Southern health regions in focus
Health Regions 11 and 12 in southern Thailand currently reported the highest case numbers, according to Ploytalay.
For Health Region 11, she cited a figure approximately 1.7 times the national level, with persistent rainfall identified as a possible contributing factor. The statement did not specify the statistical measure used for that comparison.
The government expressed concern that flooding and standing water could provide additional breeding grounds for Aedes mosquitoes, increasing the risk of dengue transmission in affected communities.
Public health personnel and village health volunteers have been instructed to alert residents, improve awareness and help communities prepare, with the aim of preventing further infections.
National case total remains below 2025 level
Despite concerns in the South, the cumulative number of dengue cases nationwide in 2026 was lower than in 2025, Ploytalay noted.
She identified August as the peak period for reported infections, citing approximately 1,450 cases compared with about 2,700 in 2025. The statement did not specify the reporting interval covered by those figures.
