The True Story: Masks Return to Care Settings

A report via Unpublished (CTV/Canadian Press) on 9 December 2025 said the Outaouais region of Quebec, Canada, made masks mandatory again in hospitals, long-term care facilities and seniors' homes.

The measure came because the flu season arrived earlier than usual and strained the region's emergency rooms. Local health authorities urged people to get vaccinated and avoid visiting patients or older people when symptomatic.

The Key Lesson: A Province's Main Hospital Gathers Patients from Every District

Thai provincial hospitals receive referrals from many districts, and ERs and wards fill up in outbreak season. Points to watch are:

• Emergency rooms where patients wait long for beds
• Referred patients arriving with several relatives
• Medical wards with extra beds in corridors
• Staff working overtime and exhausted
• Older people from care homes sent in for treatment

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 Provincial Hospitals

1. Crowded ERs with long bed waits: likelihood high / impact high / level critical. Mitigation: separate waiting zone for respiratory patients. Owner: ER head
2. No outbreak mask policy: likelihood high / impact medium / level high. Mitigation: mandate masks in clinical areas above a threshold. Owner: infection control
3. Extra beds in corridors: likelihood high / impact medium / level high. Mitigation: space beds and use screens. Owner: ward head
4. Staff fall ill together: likelihood medium / impact high / level high. Mitigation: vaccinate and plan backup staffing. Owner: nursing department
5. Rooms not disinfected after discharge: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat before the next patient. Owner: housekeeping

Ways to Reduce Flu Risk in Provincial Hospitals

1. Set thresholds for outbreak mask rules
2. Separate waiting zones for respiratory patients
3. Limit relatives of referred patients
4. Vaccinate staff
5. Plan backup staffing
6. Space extra beds and use screens
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: Where did Outaouais require masks? A: Hospitals, long-term care facilities and seniors' homes, per the 9 December 2025 report.

Q: Why bring masks back? A: Because flu season arrived earlier than usual and strained emergency rooms.

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