The True Story: Up by Half in One Week

On 1 September 2026, Singapore's Communicable Diseases Agency (CDA) reported that flu positivity rose to 36.6% in the week of 16–22 August 2026, from 24.0% the week before, and said it was monitoring closely.

The CDA said there was no indication infections were more severe than usual, and levels were below the previous peak of 43.9% in January 2025. Flu circulates year-round in Singapore, and timing varies because of travel and population mixing. It urged high-risk people to get vaccinated at least once a year.

The Key Lesson: Travel and Mixing Set the Season

Thai co-working spaces and serviced offices host members from many companies, freelancers and digital nomads. Points to watch are:

• Hot desks with different people every day
• Hourly meeting rooms booked back to back
• Pantries, coffee machines and fridges everyone uses
• Phone booths small and closed
• Members just back from abroad with symptoms

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 Co-Working Spaces and Serviced Offices

1. Hot desks not wiped between users: likelihood high / impact medium / level high. Mitigation: wipes at every desk and evening wipe-down. Owner: space manager
2. Closed phone booths never disinfected: likelihood high / impact medium / level high. Mitigation: wipe after use and ozone-treat on a schedule. Owner: space manager
3. Meeting rooms used back to back without airing: likelihood high / impact medium / level high. Mitigation: gaps between bookings and table wiping. Owner: front desk team
4. Coffee machines and fridges not wiped: likelihood high / impact low / level medium. Mitigation: wipe buttons and handles several times a day. Owner: housekeeper
5. Sick members still come in: likelihood medium / impact medium / level medium. Mitigation: communicate a work-from-home-when-sick policy. Owner: space manager

Ways to Reduce Flu Risk in Co-Working Spaces

1. Provide wipes at every hot desk
2. Leave gaps between meeting room bookings
3. Wipe coffee machines and fridges several times a day
4. Install hand sanitiser at the entrance and pantry
5. Communicate policy to work from home when sick
6. Fog work areas out of hours
7. Ozone-treat meeting rooms and phone booths on a schedule

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: How much flu did Singapore have in 2026? A: Positivity rose from 24.0% to 36.6% in the week of 16–22 August 2026, below the 43.9% peak of January 2025.

Q: Why does the flu season vary each year? A: Singapore's CDA said travel and population mixing shift the timing of outbreaks.

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