The True Story: The Deadliest Week in Five Years

Focus Taiwan (CNA) reported on 15 September 2026 that Taiwan CDC recorded 136,796 flu outpatient and emergency visits for 6–12 September, up 16.5%, expected to peak around the Mid-Autumn Festival, with A(H1N1) at 82.2% of cases.

The same week saw 21 deaths, the highest weekly total in five years, and 92 new severe cases. Data showed 65% of severe cases were 65 or older, 82.7% had underlying conditions and 68.3% had not received the latest vaccine, according to Lee Chia-lin, Deputy Director of the CDC Epidemic Intelligence Center.

The Key Lesson: Seniors Who Attend Daily Bring Viruses In and Carry Them Home

Thai elderly day care centres host many older people with chronic conditions for shared activities. Points to watch are:

• Feverish seniors sent in because family must work
• Singing and exercise in shared rooms
• Shuttle vans with close seating
• Lunch rooms with shared tables
• Carers helping many people each 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 Elderly Day Care Centres

1. Feverish seniors attend: likelihood high / impact high / level critical. Mitigation: check temperature at arrival and call family. Owner: centre nurse
2. Singing in closed rooms: likelihood high / impact medium / level high. Mitigation: open windows or move activities to airy areas. Owner: activity organiser
3. Crowded shuttles: likelihood high / impact medium / level high. Mitigation: masks on board and wipe handrails. Owner: driver
4. Seniors unvaccinated: likelihood high / impact high / level critical. Mitigation: arrange on-site vaccination. Owner: director
5. Shared rooms not disinfected: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat after closing. Owner: director

Ways to Reduce Flu Risk in Elderly Day Care Centres

1. Check temperature at arrival
2. Arrange vaccination on site before the season
3. Hold activities in airy spaces
4. Wipe shuttle handrails every trip
5. Wash hands before meals
6. Keep a separate room for symptomatic seniors
7. Fog and ozone-treat shared 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

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.
