The True Story: A Two-Day Workshop That Ended in 21 Days of Quarantine

On 28 April 2019, a 38-year-old Nigerian man arrived in Singapore. Before the trip he had been working in Delta State, Nigeria, and on 21 April he attended a wedding in a village in Ebonyi State. On 29 and 30 April he attended a workshop in Singapore. His symptoms began on 30 April, and from 1 to 7 May he stayed mostly in his hotel room. On 8 May, samples from his skin lesions confirmed mpox, making him Singapore's first case. Singapore's Ministry of Health traced 23 close contacts: 18 workshop participants and trainers, one venue staff member and four hotel staff. All were quarantined for 21 days from their exposure, and some were vaccinated.

What Meetings Businesses Should Notice

The case did not lead to further spread. But picture it from the organiser's and hotel's side. Within days, 18 attendees had to stop work to quarantine, the venue had to hand information to officials, and four hotel staff had to stay off work for 21 days.

• Training rooms have desks, chairs, microphones and equipment shared all day
• Coffee breaks bring handshakes, close conversation and shared food stations
• Hotel rooms have sheets, towels and surfaces the patient touched for days
• Housekeeping staff handle guests' linen and belongings directly

Thailand hosts a great many international conferences and training events. Hotels and venues in Bangkok, Pattaya, Chiang Mai and Phuket welcome attendees from all over the world, so this kind of risk can reach Thai businesses too.

How Mpox Spreads

According to WHO, mpox spreads through close contact, such as touching an infected person's skin or sores and prolonged face-to-face contact, and through contaminated items such as bedding, clothing and towels. The incubation period can be up to 21 days, which is why Singapore quarantined contacts for 21 days. The good news is that mpox is an enveloped virus, which suitable disinfectants can inactivate.

Where Organisers and Hotels Often Go Wrong

1. Routine cleaning only. Rubbish is collected and floors vacuumed, then the room is used again without disinfecting desks, chairs and microphones.
2. Housekeepers change linen without gloves and shake sheets, which spreads contamination.
3. No attendee list with contact details, which slows contact tracing.
4. No plan for an ill guest, so staff do not know what to do.
5. No proof of disinfection when corporate clients ask.

A Response Plan for Seminar Rooms and Hotels

1. Keep names and contact details for every attendee, in line with personal data protection law
2. Provide handwashing points or alcohol gel at room entrances and food stations
3. Ask attendees to tell the organiser if they develop fever or a rash within 21 days after the event
4. Close the patient's room first. Coordinate with public health and call 1422 in Thailand
5. Housekeepers wear gloves and masks. Roll linen inward without shaking, bag it, and wash it in hot water
6. Disinfect the guest room and meeting room fully before using them again
7. Keep a disinfection report for corporate clients and the next guests

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

10 Reasons Hotels and Conference Centres Should Have a Disinfection Plan

1. Attendees arrive from many countries on the same day
2. The long incubation period means a guest may fall ill during the event
3. Meeting rooms are used back to back several times a week
4. It protects housekeeping and service staff
5. It reduces the number of staff who must stop work
6. Corporate clients want evidence of safety
7. It also prevents respiratory and other infections
8. It protects the hotel's reputation in online reviews
9. It uses a standards-tested disinfectant instead of home mixtures
10. Rooms can reopen quickly
