The True Story: School-Age Children Hit Hardest

The Thai site Kontueleks reported on 20 September 2026, citing the Department of Disease Control (DDC), that from 1 January to 8 September 2026 there were 359,672 cumulative flu cases and 57 deaths, with the 5–9 age group having the highest rate.

The data also showed most patients had not been vaccinated, and in August A/H1N1 was the dominant strain. The DDC urged parents to vaccinate at-risk children and keep sick children home from school.

The Key Lesson: Children Living Together Around the Clock Spread Flu Fast

Thai orphanages and children's homes have children of many ages eating and sleeping together. Points to watch are:

• Shared dormitories with beds close together
• Young children sharing toys all day
• Shared bathrooms and toothbrushes kept together
• Few carers for many children
• Children not yet vaccinated against flu

How Flu Spreads

According to the World Health Organization, seasonal influenza spreads easily where people gather, such as schools and nursing homes. It spreads through droplets when people cough or sneeze, and through hands that touch contaminated surfaces and then the eyes, nose or mouth. Most people recover within a week, but young children, older adults, pregnant women and people with chronic illness are at risk of severe disease. Influenza is an enveloped virus, which suitable disinfectants can inactivate.

Risk Register for Orphanages and Children's Homes

1. Beds close together in dormitories: likelihood high / impact medium / level high. Mitigation: space beds and sleep head-to-toe. Owner: dormitory carer
2. Sick children still sleep in shared rooms: likelihood high / impact high / level critical. Mitigation: provide a separate sick room. Owner: home nurse
3. Toothbrushes kept together: likelihood medium / impact medium / level medium. Mitigation: separate holders for each child. Owner: carer
4. Children not vaccinated: likelihood high / impact high / level critical. Mitigation: arrange vaccination with health services. Owner: director
5. Bedrooms not disinfected after illness: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat bedrooms. Owner: director

Ways to Reduce Flu Risk in Children's Homes

1. Arrange vaccination for children and carers
2. Provide a sick room for ill children
3. Space beds in shared dormitories
4. Teach handwashing before meals and after toilets
5. Clean toys daily
6. Separate personal items for each child
7. Fog and ozone-treat bedrooms and play rooms

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

Q: Which children were hit hardest? A: Ages 5–9, and most patients were unvaccinated.

Q: Does the fogging disinfectant work on flu? A: The team uses Chemgene HLD4H, which meets EN 14476 for virucidal activity according to the product page, and influenza is an enveloped virus that suitable disinfectants can inactivate. Fogging does not replace vaccination or handwashing.

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

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