The True Story: A New Term Alongside HFMD

The Star, citing Vietnam News, reported on 25 August 2026 that Vietnam was recording more than 3,000 HFMD cases a week and nearly 100,000 since the start of 2026, 2.5 times the same period of 2025.

The health ministry warned that cases usually rise in September and October with the new school year, promoted the three cleans: clean food and water, clean surroundings and clean hands, and asked schools to regularly clean classrooms, toys and frequently touched surfaces.

The Key Lesson: The First Day of Term Is a Risk Day

Thai primary schools welcome all their children back at once after the break. The lessons are:

• Clean before term starts rather than waiting for illness
• Teachers check for mouth ulcers and blisters every morning
• Inform parents immediately when symptoms appear
• Shared toys and equipment need daily cleaning
• Enough handwashing points with soap are essential

How Germs Spread Through Surfaces

According to the US Centers for Disease Control and Prevention (CDC), norovirus spreads through sick people, food and contaminated surfaces. After vomiting or diarrhoea, clean and disinfect the entire area immediately with a 1,000 to 5,000 ppm chlorine bleach solution or a disinfectant with a norovirus claim, leaving it on for at least 5 minutes. For hand, foot and mouth disease, Thailand's Department of Disease Control advises cleaning classrooms, toilets and toys with suitable products such as disinfectant or diluted bleach.

Risk Register for Primary Schools

1. All children returning at once: likelihood high / impact medium / level high. Mitigation: Deep clean before term. Owner: Principal
2. Shared toys and equipment: likelihood high / impact medium / level high. Mitigation: Daily cleaning and separate sets. Owner: Class teacher
3. Too few handwashing points: likelihood medium / impact medium / level medium. Mitigation: Add basins and soap. Owner: Facilities
4. Sick children attending: likelihood medium / impact high / level high. Mitigation: Door screening and parent contact. Owner: Duty teacher
5. Children's restrooms: likelihood high / impact medium / level high. Mitigation: Several cleaning rounds a day. Owner: Housekeeping

7 Steps to Prepare Primary Schools for HFMD

1. Run germ elimination across the building before term; areas are usable about 30 minutes after ULV fogging
2. Screen children every morning: fever, mouth ulcers, hand and foot blisters
3. Provide handwashing points with soap outside classrooms and canteens
4. Clean toys and equipment daily with suitable products
5. Wipe handles, rails and desks several times a day
6. Ozone-treat the empty sick bay with nobody inside, then ventilate
7. Talk to parents about symptoms and recovering at home

How ULV Disinfection Fogging Helps

The World Health Disinfection disinfection service uses ULV fogging machines that turn the disinfectant into a fine mist. It settles across the whole area, including corners, curtains, upholstery and surfaces that hand wiping cannot reach.

• Whole-area coverage without relying on wiping spot by spot
• Quick return to use, typically about 30 minutes after fogging
• Uses Chemgene HLD4H, which meets EN 14476 for virucidal activity according to the product page
• The team wears full protective equipment, so owners and staff do not take the risk themselves
• Report and photos after the job for customers, management or authorities
• Tax invoice with 3% withholding tax for companies and agencies

Ozone Treatment for Closed Rooms and Stuffy Spaces

The World Health Disinfection ozone treatment service uses machines that generate ozone gas from oxygen in the air. It suits closed rooms such as meeting rooms, bedrooms, classrooms, sick bays and vans, helping reduce germs in the air and on surfaces and removing stale odours. Ozone breaks back down into oxygen after treatment, leaving no residue.

• Works alongside disinfection fogging: spray or wipe surfaces first, then use ozone for the air and corners of closed rooms
• No people or pets in the room during treatment: the team seals the room and runs a timer
• Ventilate after treatment before normal use resumes
• Machines tested by Intertek, according to WHD's service page
• Ideal after someone has been ill, such as recovered patients' rooms, shared bedrooms and shuttle vans

Before and After

Frequently Asked Questions

Q: What are HFMD symptoms? A: Vietnam's health ministry lists fever, mouth ulcers and blisters on palms, soles, knees or buttocks. See a doctor and rest at home.

Q: Is alcohol gel enough? A: Handwashing with soap and water should come first, and the team chooses germ elimination products suited to the germ and surface.

Q: What disinfectant does the germ elimination service use? A: The team chooses products by germ and setting, including Chemgene HLD4H, which meets EN 14476 according to the product page. For norovirus, the CDC recommends chlorine bleach or a disinfectant with a norovirus claim; ask the team to choose the right product for the job.

Q: Can I enter the room right after ozone treatment? A: No people or pets may be in the room during treatment. Ventilate afterwards before normal use; the team will advise the right time for the room size.

Q: Can schools get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.

Eliminate Germs with Disinfection Fogging and Ozone Treatment

Vietnam shows that school start is when HFMD surges. Schools that prepare early keep children learning. Reduce the risk with the World Health Disinfection disinfection service for classrooms, restrooms and canteens, and the ozone treatment service for sick bays and toy stores.
