The True Story: The Flu Season Arrives on Schedule

Kenyan outlet Citizen Digital reported on 5 March 2026 that Kenya's Ministry of Health warned of rising influenza cases in several regions, with Dr Patrick Amoth, Director General for Health, saying Kenya's flu seasons run from late February to May and July to October.

The ministry said most cases are mild, but young children, older people, pregnant women and people with chronic illnesses are at higher risk, and advised handwashing, covering coughs, staying home when sick and seeking care for severe symptoms.

The Key Lesson: Markets Are Where a Whole Town Meets Every Morning

Thai fresh and wholesale markets open before dawn, with vendors, porters and shoppers squeezed into narrow aisles. Points to watch are:

• Narrow aisles crowded in the morning
• Cash and bags passing many hands
• Market toilets without soap
• Porters working while sick
• Market offices and vendor rest rooms that are cramped

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 Fresh and Wholesale Markets

1. Crowded morning aisles: likelihood high / impact medium / level high. Mitigation: organise aisles and separate entrances and exits. Owner: market manager
2. Cash through many hands: likelihood high / impact medium / level high. Mitigation: encourage QR payment and gel at every stall. Owner: vendors
3. Toilets without soap: likelihood high / impact medium / level high. Mitigation: refill soap and clean hourly. Owner: market cleaners
4. Sick porters keep working: likelihood medium / impact high / level high. Mitigation: rest when feverish. Owner: vendors
5. Market office not disinfected: likelihood medium / impact medium / level medium. Mitigation: fog toilets and common areas after closing. Owner: market owner

Ways to Reduce Flu Risk in Fresh Markets

1. Encourage QR payment
2. Place hand gel in every zone
3. Refill toilet soap and clean hourly
4. Organise aisles to cut crowding
5. Let sick workers rest
6. Give masks to coughing vendors
7. Fog and ozone-treat toilets, offices and vendor rest rooms

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
