The True Story: An Outbreak Ahead of the Season

The Yeshiva World reported on 31 August 2026 that Beit Balev assisted-living facility in Kfar Saba, Israel had found 47 people with flu, mostly elderly residents with complex nursing needs plus some staff.

Three patients on the affected ward died, though it was unclear whether flu was the main cause. The facility tested the whole ward, gave preventive treatment to other residents and said flu had arrived before the annual vaccination campaign.

The Key Lesson: Don't Wait for the Season

Elderly care facilities and nursing homes in Thailand look after many people with chronic conditions. The lessons are:

• Flu can arrive before the season; surveillance must run all year
• Testing the whole ward shows the real size of an outbreak
• Staff can be infected and carry the virus in and out
• Preventive medication at a doctor's discretion is part of control
• Clean the whole ward, not only patients' rooms

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 Care Facilities

1. Residents with multiple conditions: likelihood high / impact high / level critical. Mitigation: Daily symptom checks and early doctor contact. Owner: Head nurse
2. Infected staff continuing to work: likelihood medium / impact high / level high. Mitigation: Sick leave for symptoms and vaccination. Owner: Manager
3. Shared activity rooms: likelihood high / impact medium / level high. Mitigation: Reduce group activities and fog. Owner: Activities team
4. Shared walkers and wheelchairs: likelihood medium / impact medium / level medium. Mitigation: Wipe after use. Owner: Care assistants
5. Visitors with symptoms: likelihood medium / impact medium / level medium. Mitigation: Screen visitors. Owner: Reception

7 Steps for Care Homes to Handle Early Flu

1. Check temperatures and symptoms daily and log them
2. Tell the doctor when several cases appear so ward-wide testing can be considered
3. Separate patients and assign dedicated staff to limit movement between wards
4. Wipe rails, wheelchairs and dining tables several times a day
5. ULV-fog common rooms and corridors; areas are usable about 30 minutes later
6. Ozone-treat rooms after patients move out with nobody inside, then ventilate
7. Plan vaccination ahead rather than waiting for the peak

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: Can flu spread outside the usual season? A: Yes. The Israeli outbreak happened in August, before the annual vaccine campaign.

Q: Can rooms with bedridden patients be fogged? A: The team plans fogging in areas where patients can be moved out; ozone treatment requires the room to be empty.

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