The True Story: A Wave of Flu Through the Hospitals

Doctors.net.uk reported on 11 December 2025 that NHS hospitals in England averaged 2,660 flu patients a day in the latest week, up from 1,717, a 55% rise in one week, compared with 1,861 at the same point the year before and just 402 in 2023.

Wes Streeting, Health Secretary, called it a wave of flu tearing through hospitals, while Professor Meghana Pandit, NHS national medical director, warned there was no peak in sight. UKHSA said H3N2 subclade K dominated and the season started about a month early.

The Key Lesson: When Beds Fill Up, Flu Patients Often End Up Beside Others

Thai private hospital wards take patients with many conditions on one floor. Points to watch are:

• Multi-bed rooms receiving flu patients
• Private rooms turned over day to day
• Relatives staying and coming and going
• Nurses covering many rooms per shift
• Lifts and corridors shared by patients and visitors

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 Private Hospital Inpatient Wards

1. Flu patients in shared rooms: likelihood high / impact high / level critical. Mitigation: cohort zones or single rooms for flu patients. Owner: ward head nurse
2. Private rooms reassigned immediately: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat before the next patient. Owner: housekeeping
3. Sick relatives stay over: likelihood high / impact medium / level high. Mitigation: screen and require masks. Owner: ward nurse
4. Nurses unvaccinated: likelihood medium / impact high / level high. Mitigation: staff vaccine drive before the season. Owner: infection control
5. Lifts and handrails not wiped: likelihood high / impact medium / level high. Mitigation: wipe touch points every 2 hours. Owner: housekeeping

Ways to Reduce Flu Risk on Inpatient Wards

1. Set up cohort zones or single rooms
2. Screen relatives and require masks
3. Vaccinate all staff
4. Wipe lifts and handrails every 2 hours
5. Place hand gel outside every room
6. Plan beds for the peak
7. Fog and ozone-treat rooms after discharge

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 many flu patients were in English hospitals? A: An average of 2,660 a day, up 55% in a week, per the 11 December 2025 report.

Q: How soon can a patient room be used after fogging? A: ULV-fogged rooms can be used about 30 minutes later; ozone treatment needs an empty room and airing first.

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