The True Story: A Traveller from an Outbreak Country

On 6 February 2025, South Sudan's National Public Health Laboratory confirmed the country's first mpox case: a 31-year-old Ugandan man who had recently travelled to Uganda, where an outbreak was ongoing.

Government and partner experts traced his contacts and monitored them closely. The health ministry activated its emergency operations centre and isolated the patient at Gudele Hospital. Many aid workers operate in the region.

The Key Lesson: Field Staff Travel Often and Live Together

Aid organisations, foundations and development agencies in Thailand regularly send staff to border and remote areas. Points to watch are:

• Field houses where rotating staff sleep in the same beds
• Field vehicles carrying both staff and the people they help
• Distribution points and mobile clinics where many people gather
• Staff who cross borders often and may pass through outbreak areas
• Shared equipment such as blankets, tents and first-aid kits

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 Aid Organisations and Field Housing

1. Staff return from outbreak areas with no symptom monitoring: likelihood medium / impact high / level high. Mitigation: self-report symptoms for 21 days after returning from outbreak areas. Owner: security manager
2. Field-house beds and blankets reused without washing: likelihood high / impact medium / level high. Mitigation: wash at every change of occupant and fog rooms on a schedule. Owner: house caretaker
3. Field vehicles not wiped after carrying patients: likelihood medium / impact high / level high. Mitigation: wipe seats and grab rails after every trip carrying patients. Owner: driver
4. Crowded distribution points with no handwashing: likelihood high / impact medium / level high. Mitigation: set up handwashing points and spaced queues. Owner: field team leader
5. No plan if staff fall ill in remote areas: likelihood low / impact high / level medium. Mitigation: hospital referral plan and an isolation room in field houses. Owner: programme director

Ways to Reduce Risk for Aid Organisations

1. Have staff report symptoms after returning from outbreak areas
2. Wash field-house bedding at every change of occupant
3. Wipe field vehicles after carrying patients
4. Set up handwashing points at distributions and mobile clinics
5. Prepare an isolation room in field houses
6. Plan hospital referrals for remote areas
7. Fog field houses and offices 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
