The True Story: A Worker Who Came Home with a New Strain

In mid-September 2024, the health department of Kerala, India, confirmed that a 38-year-old man from Malappuram district, who had just returned from the United Arab Emirates (UAE), had mpox after developing fever and a rash. He was treated in a state hospital. On 23 September 2024, genetic testing confirmed clade Ib mpox, making him India's first case of this strain, the same one that led WHO to declare a global emergency in August 2024. Days later, Kerala confirmed a second case in Ernakulam district, also a UAE returnee. The state issued revised guidelines on traveller surveillance and close-contact tracing.

Why This Matters for Worker Accommodation in Thailand

Kerala has many workers who go to the Gulf countries and come home regularly. Thailand likewise has Thai workers abroad and a large number of migrant workers from Myanmar, Laos and Cambodia living in staff dormitories and construction camps. Worker accommodation often has features that let infections spread easily:

• Shared bedrooms with bunk beds, mattresses and blankets passed from person to person
• Shared toilets and showers used by dozens of people per room
• Shared laundry and drying areas where many people's clothes mix
• Frequent turnover, with new workers and people returning from home or abroad
• Workers afraid to report symptoms for fear of losing income or their job

Thailand also reported an imported clade Ib case in 2024, according to the Department of Disease Control.

How Mpox Spreads in Shared Accommodation

According to the World Health Organization, mpox spreads through close contact with an infected person's skin or sores and through contaminated items such as bedding, clothing and towels. In shared bedrooms where people sleep close together and share fabrics, the chance of contact is higher than in an ordinary home. Mpox is an enveloped virus, which suitable disinfectants can inactivate.

Where Employers and Dormitory Managers Often Go Wrong

1. No screening for workers just back from abroad or other areas
2. Mattresses and blankets passed on to new workers without washing or disinfection
3. Shared toilets not cleaned often enough
4. No isolation room for people with symptoms, so a sick worker keeps sleeping with others
5. Communication only in Thai, so migrant workers do not understand the advice

A Prevention Plan for Worker Dormitories and Construction Camps

1. Screen new workers and returnees: ask about fever, rash and travel history
2. Communicate in several languages, including Thai, Burmese, Lao and Khmer, with pictures
3. Let workers report symptoms without penalty, and take them to a doctor
4. Set up a temporary isolation room for people with suspected infectious illness
5. Give each person their own mattress and blanket, and wash them in hot water before passing them on
6. Clean and disinfect shared toilets several times a day
7. Fog the shared bedroom fully when a suspected case appears, and after the patient moves out
8. Coordinate with the local hospital and public health office, and call 1422 in Thailand

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 Employers Should Have a Disinfection Plan for Worker Housing

1. Shared bedrooms let infections spread fast
2. Workers come and go and travel home often
3. It reduces the risk of a construction site or production line stopping
4. It protects the health of the workers at the heart of the business
5. It reduces worry and rumours among workers
6. It shows responsibility to staff, in line with labour standards checked by overseas customers
7. It also prevents other infections in shared housing, such as skin and respiratory diseases
8. It uses a standards-tested disinfectant instead of guesswork bleach mixtures
9. It provides reports for customer and agency audits
10. It comes with a tax invoice for company expense records
