The True Story: Superflu Begins Spreading Locally

MercoPress reported on 7 January 2026 that Argentine health authorities were concerned over a growing number of superflu cases, with 18 cases found, 9 confirmed as H3N2 subclade K, and 5 hospitalised.

The report said most cases were acquired locally rather than abroad, meaning the virus had begun circulating in the community. Authorities stepped up surveillance and urged at-risk groups to get vaccinated.

The Key Lesson: Tens of Thousands in One Place Give the Virus a Chance

Thai football grounds, boxing stadiums and concert halls gather tens of thousands of fans shouting and singing together. Points to watch are:

• Entrances and exits with packed queues
• Standing zones by the stage crowded all night
• Toilets at half-time or set changes
• Shared dressing rooms for athletes and artists
• Food stalls inside at peak times

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 Stadiums and Concert Venues

1. Crowded entrances: likelihood high / impact medium / level high. Mitigation: open more gates and stagger entry. Owner: venue manager
2. Standing zones packed all event: likelihood high / impact medium / level high. Mitigation: cap zone numbers and recommend masks in outbreaks. Owner: event organiser
3. Toilets crowded at breaks: likelihood high / impact medium / level high. Mitigation: more cleaning rounds and soap refills. Owner: housekeeping
4. Shared dressing rooms: likelihood medium / impact high / level high. Mitigation: clean before and after each team or artist. Owner: facilities team
5. Venue not disinfected after events: likelihood medium / impact medium / level medium. Mitigation: fog and ozone-treat dressing rooms after events. Owner: venue manager

Ways to Reduce Flu Risk in Stadiums and Concert Venues

1. Open more gates to cut queues
2. Place handwash points at every entrance
3. Recommend masks at outbreak peaks
4. Clean toilets at every break
5. Clean dressing rooms before and after each team
6. Announce that sick ticket holders can stay home and get refunds
7. Fog and ozone-treat dressing rooms and lounges

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

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