The True Story: From a Quarantine Room to an Outdoor Recreation Centre

On 6 September 2022, the Hong Kong government confirmed its first mpox case: a 30-year-old man who had arrived from the Philippines, detected while in hotel quarantine under the entry rules at the time.

A few weeks later it was reported that the authorities would convert an outdoor recreation centre into a quarantine facility for mpox contacts. A camp-style site with dormitories and shared bathrooms was chosen because it can separate people, but it needs strict cleaning.

The Key Lesson: Shared Dormitories and Bathrooms in Camps Need a Cleaning Plan

Youth camps, scout camps and outdoor camps in Thailand host hundreds of young people per intake. Points to watch are:

• Camp mattresses, pillows and blankets that rotate every intake
• Shared toilets and showers used by dozens of children at once
• Activity equipment such as life jackets, helmets and ropes
• Rental tents and sleeping bags that must be washed and aired before the next group
• The camp sick bay which must be able to separate unwell children

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 Youth and Outdoor Camps

1. Blankets and pillowcases not washed between intakes: likelihood high / impact high / level critical. Mitigation: hot-wash every intake and wipe mattresses with disinfectant. Owner: camp manager
2. Rental sleeping bags and tents reused immediately: likelihood medium / impact high / level high. Mitigation: wash or wipe and air-dry before renting again. Owner: equipment team
3. Children with rashes not separated: likelihood medium / impact high / level high. Mitigation: leaders do basic skin checks and a separate sick bay is ready. Owner: camp nurse
4. Shared bathrooms cleaned once a day: likelihood high / impact medium / level high. Mitigation: increase to morning and evening and after outdoor activities. Owner: head of housekeeping
5. Wearable equipment shared: likelihood medium / impact medium / level medium. Mitigation: wipe helmets and life jackets after each group. Owner: activity instructor

Ways to Reduce Risk in Youth Camps

1. Hot-wash blankets and pillowcases every intake
2. Fog the dormitories before a new intake
3. Clean shared bathrooms at least twice a day
4. Children use their own towels never shared
5. Wipe wearable equipment after each group
6. Check symptoms on arrival and every morning
7. Tell parents at once about an unexplained rash

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
