The True Story: No Need to Panic, but Prevention Matters

Manila Bulletin reported on 12 January 2026 that the Philippine Department of Health (DOH) had logged 63 influenza H3N2 subclade K cases as of 27 December 2025, and all had recovered.

Albert Domingo, DOH spokesperson, said the World Health Organization had found no evidence that subclade K causes more severe illness, and masks were voluntary, but people with symptoms should stay home, wash hands and get vaccinated.

The Key Lesson: Crowds, Shouting over Music, Shared Glasses

Thai bars, pubs, karaoke venues and nightclubs are busiest during year-end festivities. Points to watch are:

• Dance floors packed with people
• Karaoke rooms closed with shared microphones
• Glasses and tasting straws shared
• Toilets at the busiest hours
• Staff working late with little rest

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 Bars, Pubs and Nightlife Venues

1. Shared karaoke microphones: likelihood high / impact medium / level high. Mitigation: mic covers and wipes at every room change. Owner: venue manager
2. Closed karaoke rooms: likelihood high / impact medium / level high. Mitigation: air rooms between groups. Owner: room attendant
3. Glasses not properly washed: likelihood high / impact medium / level high. Mitigation: hot-water or glasswasher cleaning. Owner: bar head
4. Sick staff keep working: likelihood medium / impact high / level high. Mitigation: stand down with fever. Owner: venue manager
5. Venue not disinfected after closing: likelihood medium / impact medium / level medium. Mitigation: fog and ozone-treat karaoke rooms after closing. Owner: owner

Ways to Reduce Flu Risk in Nightlife Venues

1. Use mic covers and wipe every round
2. Air karaoke rooms between groups
3. Wash glasses in hot water
4. Place hand gel at entrances and bars
5. Let sick staff rest
6. Clean toilets hourly at peak
7. Fog and ozone-treat karaoke rooms 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
