The True Story: Two Young Children in ICU

Greek newspaper To Vima reported on 23 January 2026 that two children aged 3 and 6 were in intensive care at a major paediatric hospital in Athens with flu, with the 6-year-old intubated and the 3-year-old more stable.

Greece's National Public Health Organization (EODY) said vaccination remains the most effective protection and advised prompt medical attention, timely antivirals when appropriate, masks in crowded indoor spaces, frequent handwashing and good ventilation.

The Key Lesson: Warm, Humid Changing Rooms Young Children Share

Thai children's swim schools and indoor pools teach young children in groups while parents wait in enclosed areas. Points to watch are:

• Changing rooms and showers warm and humid
• Float rings and foam aids shared
• Parents waiting in enclosed poolside areas
• Children with runny noses still attending their course
• Swim teachers in contact with many groups a day

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 Children's Swim Schools and Indoor Pools

1. Sick children attend: likelihood high / impact high / level critical. Mitigation: make-up lessons for sick children. Owner: school manager
2. Humid changing rooms: likelihood high / impact medium / level high. Mitigation: ventilate and clean every session. Owner: housekeeper
3. Shared float aids: likelihood high / impact medium / level high. Mitigation: clean equipment after every class. Owner: swim teacher
4. Crowded parent waiting area: likelihood high / impact medium / level high. Mitigation: one parent per child. Owner: receptionist
5. Changing rooms not deep-cleaned: likelihood medium / impact medium / level medium. Mitigation: fog and ozone-treat changing rooms after closing. Owner: owner

Ways to Reduce Flu Risk in Children's Swim Schools

1. Offer make-up lessons for sick children
2. Ventilate changing rooms
3. Clean float aids after every class
4. Limit parents to one per child
5. Use personal towels
6. Vaccinate swim teachers
7. Fog and ozone-treat changing rooms after closing

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: How old were the Greek children in ICU? A: 3 and 6, with the 6-year-old intubated, per the 23 January 2026 report.

Q: What did EODY advise? A: Vaccination, prompt care, antivirals when appropriate, masks in crowded indoor spaces, handwashing and good ventilation.

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