Top 10 Foggers and Disinfectants for Bangkok Schools and Preschool Child Development Centres: Lessons from Bangkok Sets School Disease Measures, Closing Classrooms After Two HFMD Cases, 2026
Bangkok issued measures for the first 2026 semester: screen students, separate those with symptoms, clean classrooms and toilets, and close a classroom for at least a day when two HFMD cases occur in one week. What should schools and childcare centres prepare?
The Real Story from the News: Clear Criteria for Closing a Classroom
Bangkok announced on 20 May 2026 that schools must screen students and staff, separate symptomatic people immediately, and regularly clean buildings, classrooms and toilets.
A classroom closes for at least one day of cleaning when two or more HFMD cases occur in one room within a week, or one EV71 case is found; child development centres must clean toys daily and open windows instead of using air-conditioning when a child is ill.
Why Choosing the Right Equipment Matters
Bangkok's measures are a model schools and childcare centres nationwide can adopt: morning screening, separating sick children, daily cleaning and clear closure criteria. Cleaning during closures should use enterovirus-labelled products, since alcohol gel works poorly on this virus group.

Before and After Using the Right Equipment

After: One standard across schools, daily cleaning and system reporting.
Prefer Not to Do It Yourself? Use a Professional Service
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Frequently Asked Questions
Q: When should a classroom close? A: Under Bangkok's measures, at least one day when two or more HFMD cases occur in one room within a week, or one EV71 case is found.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Health References
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
Summary
Bangkok's measures show clear criteria let schools act fast and consistently. Schools that follow them protect children well.
