In 2025, allergic diseases in Thailand have reached epidemic levels. According to the Thai Society of Allergy, Asthma & Immunology (TSAI) and the Ministry of Public Health (MoPH), around 14.8 million people suffer from allergic rhinitis, asthma, food, and skin allergies. This is over 21% of the population.
The rate is especially high among children and teens: 1 in 3 schoolchildren experiences allergy symptoms. In response, TSAI, MoPH, and the Department of Disease Control (DDC) have launched a national prevention campaign, including free screenings, education programs, and digital consultations.
Main Causes of Rising Allergies
Experts identify key factors:
- Air pollution: PM2.5 in Bangkok exceeds safe levels 3–5x during smog season (Jan–Apr);
- Climate change: longer pollen seasons;
- Urban lifestyle: sedentary habits, lack of sunlight, stress;
- Microbiome disruption: excessive hygiene, antibiotics, processed foods;
- Improper cosmetic use: especially among teenage girls.
Allergic Rhinitis: The Main Challenge
The most common condition is allergic rhinitis (hay fever), affecting over 10 million people. Symptoms include:
- Sneezing, nasal congestion, watery eyes;
- Headaches, fatigue, poor concentration;
- Poor sleep and academic performance in children.
Annual healthcare costs for allergies in Thailand are estimated at 82 billion THB, including medication, doctor visits, and lost productivity.
National Campaign 2025
From December 1–7, 2024, Allergy Awareness Week in Thailand was held with 500 doctors and 120 clinics nationwide. Services included:
- Free allergy screenings (pollen, dust mites, mold, food);
- Allergist consultations in clinics and shopping malls;
- Educational lectures in schools and universities;
- Digital chatbots on LINE and Facebook for symptom checks.
Allergy Care Network
Since 2023, the "Allergy Under Control" project has been active:
- 62 specialized clinics in 30 provinces;
- Training for 1,200 general practitioners in allergy diagnosis and treatment;
- Mobile clinics for remote areas;
- National allergy registry for personalized monitoring.
Outlook 2025–2030
Expected:
- 15% reduction in allergy rates by 2030;
- Development of personalized immunotherapy (allergy vaccines);
- Creation of a national allergen map with risk forecasting;
- International recognition of Thailand’s allergy prevention model.
"Allergies are not just a runny nose, but a chronic disease," said TSAI President Dr. Prae Pongpiwan. "Investing in prevention today will save billions tomorrow."
