The True Story: Cross-Border Travellers Found at the Border

In late July 2024, the Rwanda Biomedical Centre (RBC) confirmed two mpox cases: a 33-year-old woman and a 34-year-old man, both with a history of frequent travel to the Democratic Republic of the Congo.

Officials said one symptomatic patient was detected at the border and given treatment. It shows that screening along travel routes can find cases, and frequent travellers often share public transport with others.

The Key Lesson: Long-Distance Passengers Sit Side by Side for Hours

Coaches, intercity vans and cross-border buses in Thailand run many trips a day. Points to watch are:

• Fabric seats and headrest covers leaned on for hours
• Blankets on coaches handed out to passengers
• On-board toilets used throughout the journey
• Grab rails and armrests touched by everyone
• Driver rest rooms at terminal stations

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 Long-Distance Buses

1. Coach blankets reused across trips: likelihood high / impact high / level critical. Mitigation: change blankets every trip and hot-wash them. Owner: depot manager
2. Headrest covers not changed: likelihood high / impact medium / level high. Mitigation: use removable washable covers and change every trip. Owner: on-board attendant
3. On-board toilet not cleaned en route: likelihood medium / impact medium / level medium. Mitigation: wipe at rest stops and clean fully at the terminal. Owner: relief driver
4. Passenger with a rash sits next to others: likelihood low / impact high / level medium. Mitigation: announce symptom reporting and seat separately where possible. Owner: ticket staff
5. Bus never disinfected as a whole: likelihood medium / impact medium / level medium. Mitigation: fog buses on a schedule at the depot. Owner: fleet manager

Ways to Reduce Risk on Long-Distance Buses

1. Change blankets every trip and hot-wash them
2. Change headrest covers every trip
3. Wipe grab rails and armrests after passengers get off
4. Wipe the on-board toilet at rest stops
5. Carry hand sanitiser on board for passengers
6. Fog the whole bus on a schedule at the depot
7. Ask passengers to report symptoms before boarding

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

Prevent It with a Disinfection Service and Chemgene HLD4H

The true story from Rwanda is a reminder that frequent travellers share buses with others every day. Bus companies that change linen every trip and disinfect on schedule protect passengers and staff. Prevent it with the World Health Disinfection disinfection service for coaches, intercity vans and bus stations, and Chemgene HLD4H disinfectant for wiping grab rails, armrests and on-board toilets.
