The True Story: Almost All the Deaths Were Older People

PTAheute, summarising Robert Koch Institute (RKI) data, reported that Germany's 2025/26 flu wave began in week 48 of 2025, two to three weeks earlier than the previous two seasons, and ended after 15 weeks.

Over the season there were 236,853 lab-confirmed cases, 63,249 (27%) of them hospitalised, and 1,922 deaths, 95% in people aged 60 or over. Influenza A(H3N2) made up about 71% and A(H1N1)pdm09 about 28%.

The Key Lesson: Common Areas Older Residents Share Every Day

Thai senior residences and condominiums have many residents over 60 sharing lifts, dining rooms and activity rooms. Points to watch are:

• Lifts older residents use all day
• Shared dining and activity rooms
• Gyms and indoor pools that are humid
• Housekeepers and aides entering many rooms a day
• Visiting family at weekends

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 Senior Residences and Condominiums

1. Lifts and handrails rarely wiped: likelihood high / impact medium / level high. Mitigation: wipe lift buttons and handrails every 2 hours. Owner: juristic person
2. Crowded activity rooms: likelihood high / impact medium / level high. Mitigation: limit numbers and ventilate in outbreaks. Owner: project manager
3. Housekeepers enter many rooms: likelihood medium / impact high / level high. Mitigation: vaccinate and wash hands between rooms. Owner: housekeeping manager
4. Sick visitors: likelihood medium / impact high / level high. Mitigation: post notices asking sick visitors to postpone. Owner: juristic person
5. Rooms not disinfected after illness: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat rooms after recovery. Owner: project manager

Ways to Reduce Flu Risk in Senior Residences

1. Arrange vaccination on site before the season
2. Wipe lift buttons every 2 hours
3. Place hand gel at every common area
4. Ventilate activity rooms
5. Ask sick visitors to postpone
6. Deliver meals to sick residents
7. Fog and ozone-treat rooms and common areas

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

Frequently Asked Questions

Q: How many flu deaths did Germany's season have? A: 1,922, with 95% aged 60 or over, per RKI data.

Q: What share of cases were hospitalised? A: 63,249, or 27% of the 236,853 confirmed cases.

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