The True Story: Tunisia Prepares for Flu Season

Tunisie Numérique reported on 29 October 2025 that the technical commission for the prevention of seasonal flu and acute respiratory diseases met under Health Minister Dr Mustapha Ferjani to review seasonal flu, imported flu and avian flu.

It decided to strengthen surveillance and early detection in hospitals and laboratories, expand vaccination for vulnerable groups, train medical staff in rapid diagnosis and promote handwashing, masks when symptomatic and avoiding crowded places.

The Key Lesson: Testing Points Are Where Patients Gather

Private testing labs and collection points in Thailand see people with fever and cough every day in small waiting rooms.

• People tested for flu may be infectious, so separate them from routine health checks
• Collection rooms are used all day and need cleaning between patients
• Staff need training in protective equipment and cleaning
• Early detection helps control outbreaks, but testing points must not spread infection
• Symptomatic visitors should wear masks from the entrance

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 Testing Labs and Sample Collection Points

1. Symptomatic visitors mixing with health-check clients: likelihood high / impact high / level critical. Mitigation: Separate entrance and waiting area for symptomatic visitors. Owner: Lab manager
2. Collection rooms contaminated between patients: likelihood high / impact medium / level high. Mitigation: Wipe between patients and fog after closing. Owner: Collection staff
3. Staff infected: likelihood medium / impact high / level high. Mitigation: Protective equipment, training and vaccination. Owner: Chief medical technologist
4. Small waiting rooms with poor airflow: likelihood medium / impact medium / level medium. Mitigation: Cap waiting numbers and ozone-treat after closing. Owner: Facilities
5. Mobile collection vehicles: likelihood medium / impact low / level low. Mitigation: Wipe and ozone-treat vehicles regularly. Owner: Mobile services

7 Steps to Make a Flu Testing Point Safe

1. Separate the entrance for fever and cough from routine health checks
2. Ask symptomatic visitors to wear masks from the door
3. Use online queueing to reduce waiting crowds
4. Wipe chairs and tables in collection rooms between every patient
5. Fog waiting and collection rooms daily after closing in flu season
6. Ozone-treat waiting rooms and collection vehicles when empty
7. Train staff in donning and doffing protective equipment

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: Does fogging affect lab equipment? A: Tell the team so they can assess the space and equipment and plan accordingly.

Q: When can the waiting room be used after fogging? A: Typically about 30 minutes later.

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