Top 10 Foggers and Disinfectants for Primary Schools: Lessons from Sabah's School Closures for Cleaning as HFMD Passed 4,000 Cases, 2025
Sabah recorded 4,385 HFMD cases and five schools closed temporarily for cleaning and disinfection. What should Thai primary schools prepare?
The Real Story from the News: Five Schools Closed to Break the Chain
The Vibes reported on 1 May 2025 that the Sabah Health Department recorded 4,385 HFMD cases from 1 January to 19 April 2025, 83% in under-sevens, with clusters at 10 schools and five fully closed.
The five schools closed temporarily for cleaning and disinfection to break the chain of infection, while others closed only affected classes. Advice included regularly disinfecting toys, bathroom surfaces and shared items, not sharing towels or toothbrushes and keeping sick children home.
Why Choosing the Right Equipment Matters
Primary schools have hundreds of pupils sharing toilets, taps and desks, and younger pupils can't yet manage their own hygiene well. Sabah shows that when clusters appear, closing for cleaning and disinfection breaks the chain, so schools need both a fast closure-clean plan and daily routines that make closures less likely.

How to Use Them Effectively
- No shared towels or toothbrushes as Sabah advised
- Wipe bathroom surfaces with HLD4H twice daily
- Wipe desks and materials with HLD4L daily
- Keep sick pupils home and see a doctor
- Prepare a closure-clean plan with U240 fogging; usable about 30 minutes after ULV fogging
Before and After Using the Right Equipment
Before: No cluster plan, so closures dragged on without direction.
After: Daily routines and a one-day closure-clean plan. Lessons resume quickly.
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: Why did Sabah close schools for cleaning? A: To clean and disinfect and break the chain of infection after clusters appeared.
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
Sabah shows HFMD can stop schools. Schools with both daily routines and response plans protect children's learning.
