Atlanta News First reported the Fulton County Board of Health notifying Johns Creek High School students and staff of possible TB exposure from a diagnosed person at the school, with free testing for close contacts. What should Thai schools prepare?
Atlanta News First reported on 25 June 2026 that the Fulton County Board of Health sent letters saying students and staff may have been exposed to TB from a diagnosed person at the school.
Close contacts received a second letter with free screening appointments at the North Fulton Regional Health Center, and officials noted not everyone exposed becomes sick.
Thailand still has many TB cases. Secondary schools with thousands of students in air-conditioned rooms need a plan with health officials when a case appears. TB is airborne and treated mainly with medication by doctors; contact screening, ventilation and classroom cleaning support this.

Before: Rumours spread, parents panicked and no one knew who needed testing.
After: Systematic letters, contact screening and ventilation.
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: Does disinfection prevent TB? A: It is not the main measure. TB is airborne and needs screening, medical treatment and ventilation; cleaning is supporting hygiene.
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.
Johns Creek shows systematic notification and screening reduce panic. Schools with plans alongside health officials cope well.
