The True Story: Asia's First Clade Ib Case

On 23 August 2024, Thailand's Department of Disease Control confirmed that a 66-year-old European man who travelled from Africa and arrived in Bangkok on 14 August had clade Ib mpox, the first such case in Asia.

Officials monitored 43 contacts for 21 days and required arrivals from 42 at-risk countries to register on entry to Thailand.

The Key Lesson: Guides Are Close to Tourists from the Airport Onward

Guides, drivers and inbound tour staff meet foreign tourists before anyone else. Points to watch are:

• Luggage handling and handshakes at the airport
• Van and coach seats and rails reused every group
• Guide microphones shared by several people
• Cold towels and water bottles taken from a shared box
• No channel for reporting symptoms during the 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 Inbound Tour Operators

1. Tourists with rash or fever have no way to report it: likelihood medium / impact high / level high. Mitigation: guides ask about symptoms and follow a doctor-referral procedure. Owner: tour manager
2. Vans and coaches not disinfected between groups: likelihood high / impact medium / level high. Mitigation: wipe seats and rails between groups and fog on a schedule. Owner: fleet supervisor
3. Guide microphones shared without wiping: likelihood high / impact low / level medium. Mitigation: wipe mics and use replaceable foam covers. Owner: guide
4. Guides not briefed on arrivals from at-risk countries: likelihood medium / impact medium / level medium. Mitigation: train guides on DDC announcements. Owner: operations manager
5. No sanitiser on vehicles: likelihood medium / impact low / level low. Mitigation: install sanitiser in every vehicle. Owner: fleet supervisor

Ways to Reduce Risk for Inbound Tours

1. Train guides on DDC announcements
2. Ask about symptoms politely each day
3. Follow a doctor-referral procedure for rash or fever
4. Wipe seats and rails between groups
5. Wipe guide microphones daily
6. Install sanitiser in every vehicle
7. Fog whole vehicles on a schedule

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
