On November 11, Deputy Permanent Secretary of the Ministry of Public Health Dr. Weerawut Imsamran led a meeting to address Thailand’s medical and public health preparedness for the upcoming air pollution season, specifically targeting fine particulate matter (PM2.5) concerns in 2024. With the ongoing La Niña conditions predicted to last until January, officials expect improved air quality from late 2023 to mid-2024 due to increased rainfall and moisture that should limit fire risks. However, authorities urge continued vigilance, especially in areas like Bangkok and the Northeast, where PM2.5 levels may temporarily increase from November 12-18 due to closed weather conditions and agricultural burning.
The Ministry reviewed a draft plan to enhance proactive public health measures, including four main strategies: raising public awareness, minimizing health impacts, expanding healthcare services, and boosting management efficiency. Efforts will include digital tools like the “Mor Prom” app to improve information outreach, especially for vulnerable groups such as children, the elderly, pregnant women, and those with respiratory or cardiac conditions.
The emergency response levels (PHEOC) for PM2.5 pollution were also updated. These range from basic health protocols for PM2.5 levels under 37.5 µg/m³ to restrictive measures—such as work-from-home policies and control of pollution sources—when levels reach 75.1 µg/m³ or higher. The highest alert, triggered if PM2.5 levels exceed 150 µg/m³ for five consecutive days, would enforce aggressive health protections and discourage outdoor activities.
