The Real Story from the News: Wash 30 Seconds, Cook at 85°C
Busan announced on 11 March 2026 that group activities in schools and daycare centres rise at semester start, warning of norovirus, Salmonella, E. coli and Campylobacter.
Advice was soap handwashing under running water for at least 30 seconds, cooking to an 85°C core for at least one minute, separate knives and boards, and staying home after two or more episodes of diarrhoea or vomiting.

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 wash for 30 seconds? A: Busan advised at least 30 seconds with soap under running water so lather can thoroughly remove germs from the skin.
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.
