The True Story: Crossing the Border Without Symptoms

A 32-year-old Tanzanian man crossed from Tunduma, Tanzania, into Nakonde, Zambia, on 2 September 2024 without symptoms. He later sought care on 2 October.

Laboratory tests confirmed mpox on 4 and 8 October 2024, making him Zambia's first recorded case, treated in Central Province. It shows that border screening may miss people who do not yet have symptoms.

The Key Lesson: Roadside Stops Serve Long-Distance Travellers Day and Night

Truck stops, petrol stations and highway rest areas in Thailand serve long-haul drivers and travellers from every region. Points to watch are:

• Toilets and showers used by truck drivers all night
• Driver rest rooms or bunks changing users every few hours
• Fuel nozzle handles and payment machines touched by everyone
• Roadside eateries where tables change customers constantly
• People without symptoms yet whom border screening may miss

How Mpox Spreads

According to the World Health Organization, mpox spreads mainly through close contact with an infected person's skin or sores, and can also spread through contaminated objects such as clothing, bedding and towels. Mpox is an enveloped virus, which suitable disinfectants can inactivate.

Risk Register for Truck Stops and Petrol Stations

1. Driver showers not cleaned at night: likelihood high / impact medium / level high. Mitigation: night-time wiping rounds with a posted cleaning schedule. Owner: rest stop manager
2. Driver bunks not given fresh linen: likelihood high / impact high / level critical. Mitigation: change sheets for every user and wipe faux-leather mattresses. Owner: rest room attendant
3. Fuel nozzles and payment machines not wiped: likelihood high / impact low / level medium. Mitigation: wipe every 2 hours with hand sanitiser nearby. Owner: forecourt staff
4. Travellers do not know where to get care for a rash: likelihood medium / impact medium / level medium. Mitigation: post nearby hospital details and hotline 1422. Owner: rest stop manager
5. No disinfection schedule for the building: likelihood medium / impact medium / level medium. Mitigation: fog toilets and rest rooms on a schedule. Owner: business owner

Ways to Reduce Risk at Truck Stops

1. Add night-time cleaning for toilets and showers
2. Change bunk linen for every user
3. Wipe fuel nozzles and payment machines on a schedule
4. Place hand sanitiser at every payment point
5. Post hospital details and hotline 1422
6. Fog toilets and rest rooms on a schedule
7. Wipe eatery tables whenever customers leave

How ULV 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 fully reach.

• Whole-area coverage without relying on wiping spot by spot
• Quick return to use, typically about 30 minutes after fogging
• The team wears full protective equipment, so owners and staff do not take the risk themselves
• Report and photos after the job to show customers, management or authorities
• Tax invoice with 3% withholding tax for companies and agencies
• More than 5 years of experience in hospitals, offices, hotels and public buildings

The Disinfectant We Use: Chemgene HLD4H

The team uses Chemgene HLD4H. According to WHD's product page, it meets the EN 14476 standard for virucidal activity, is used in NHS hospitals in England, and is endorsed by Mahidol University. We do not claim that Chemgene has been tested against mpox specifically. But mpox is an enveloped virus, which suitable disinfectants can inactivate when used at the manufacturer's stated concentration and contact time.

• No harsh bleach smell
• Works on many surfaces, from desks and counters to handles and equipment
• Can be bought for daily wiping of high-touch points
