The True Story: Numbers Fell, but the Risk Remains

A Xinhua report on 6 June 2026 said Australia recorded 33,071 flu cases from 1 January to 31 May 2026, about 65% fewer than the 96,422 in the same period of 2025, which the Australian CDC called the deadliest flu year this century, with 1,701 deaths.

Experts warned against a false sense of security, as the Super-K strain still caused most infections and cases rose 15% in late May, while only about 16% of adults aged 18–49 were vaccinated. Catherine Bennett of Deakin University said the peak might be delayed until later in the year.

The Key Lesson: Working Adults Rarely Vaccinate and Often Exercise While Sick

Thai gyms have working-age members sharing equipment from morning to night. Points to watch are:

• Dumbbells, bars and machine handles held by sweaty hands in turn
• Bench pads and yoga mats touching faces and bodies
• Group class rooms with heavy breathing in a closed room
• Locker rooms and saunas that are damp
• Members who train while sick believing they will recover faster

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 Gyms and Fitness Centres

1. Sick members still train: likelihood high / impact medium / level high. Mitigation: signs urging rest and free temporary membership freezes. Owner: gym manager
2. Equipment not wiped after use: likelihood high / impact medium / level high. Mitigation: disinfectant in every zone and staff wiping rounds. Owner: floor trainer
3. Closed group class rooms: likelihood high / impact medium / level high. Mitigation: ventilate between classes and ozone-treat after closing. Owner: gym manager
4. Loaned yoga mats not cleaned: likelihood medium / impact medium / level medium. Mitigation: wipe after use and encourage personal mats. Owner: yoga teacher
5. Damp locker rooms: likelihood medium / impact medium / level medium. Mitigation: clean several times a day and fog on a schedule. Owner: facilities team

Ways to Reduce Flu Risk in Gyms

1. Post signs urging rest when ill
2. Provide disinfectant in every equipment zone
3. Wipe equipment before and after use
4. Use personal mats and towels every time
5. Ventilate group class rooms
6. Encourage vaccination for members and staff
7. Fog and ozone-treat class rooms and lockers after closing

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: Why did Australian experts warn despite falling cases? A: Super-K still caused most infections, cases began rising again, and vaccination among working-age adults was low.

Q: Should you exercise with flu? A: Rest until the fever is gone. Exercising with a fever doesn't speed recovery and can spread the virus.

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

Prevent Flu with Disinfection Fogging and Ozone Treatment

The true story from Australia shows falling numbers do not mean safety. Gyms that care for equipment and closed rooms let members train with confidence. Reduce the risk with the World Health Disinfection disinfection service for equipment zones, restrooms and common areas, and the ozone treatment service for group class rooms and locker rooms.
