The True Story: A Case After a Trip Around Europe

On 12 July 2022, Russia confirmed the country's first mpox case, in Moscow: a man who had recently returned from a trip around Europe, with mild, non-life-threatening symptoms.

Everyone he had contact with was identified and placed under medical observation. Visiting several cities in one trip means sharing beds and transport with many people.

The Key Lesson: Train Bedding Changes Users Every Trip

Sleeper trains in Thailand run overnight to Chiang Mai, Nong Khai and the south, with passengers sleeping on the same berths trip after trip. Points to watch are:

• Sheets, pillowcases and blankets that must be changed for every passenger
• Mattresses and pillows in skin contact all night
• On-board toilets and washbasins shared by the whole carriage
• Ladders to upper berths and grab rails touched by everyone
• Bed-making staff who handle dozens of used sets per trip

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 Sleeper Trains

1. Sheets and pillowcases not changed for every passenger: likelihood low / impact high / level medium. Mitigation: change every trip, checked by the train manager. Owner: bedding contractor
2. Mattresses and pillows never disinfected: likelihood high / impact medium / level high. Mitigation: use protective covers and fog sleeper cars on a schedule at the terminus. Owner: carriage maintenance
3. Staff handle used linen bare-handed and shake it: likelihood high / impact medium / level high. Mitigation: wear gloves, roll linen inwards and bag it immediately. Owner: head of bed-making staff
4. On-board toilets not cleaned enough: likelihood high / impact medium / level high. Mitigation: wipe on a schedule en route and clean fully at the terminus. Owner: on-board service staff
5. No way for passengers with rashes to report: likelihood low / impact high / level medium. Mitigation: announce a reporting channel and separate berths where possible. Owner: train manager

Ways to Reduce Risk on Sleeper Trains

1. Change sheets and pillowcases for every passenger
2. Hot-wash linen and dry fully
3. Use protective covers on mattresses and pillows
4. Wear gloves to collect used linen and do not shake it
5. Wipe ladders and grab rails before new passengers board
6. Fog sleeper cars at the terminus on a schedule
7. Wipe on-board toilets en route

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
