South Korea's flu-like illness rate peaked at 36.5 per 1,000 outpatients among 7–12-year-olds, with the season about a month early. What should tutoring schools with tightly packed classrooms prepare?
Financial News reported on 9 September 2026, citing the KDCA, that South Korea's flu season started about a month early, with the week-35 flu-like illness rate at 13.3 per 1,000 outpatients and highest among children aged 7–12 at 36.5.
Flu detection reached 12.3% versus 1.1% in 2025, led by A(H1N1)pdm09. The KDCA expects the vaccine to work against it and asked people with fever to stay home from work or school.
Tutoring schools pack pupils from many schools into closed, air-conditioned rooms for several sessions a day, sharing desks, mics and pens, and sick children often still attend for fear of falling behind. Letting sick pupils join online, ventilating and wiping desks between sessions reduce spread across schools.

Before: Sick pupils still attended and desks were reused all day unwiped.

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.
Q: Why offer online classes for sick pupils? A: The KDCA asks people with fever to stay home, and pupils from many schools mix at tutoring centres.
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.
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.
Korea shows flu among schoolchildren can surge fast. Tutoring schools with clear health policies protect both health and learning.
