The True Story: The Family That Closed a Classroom

On 16 December 2024, German health officials reported four clade Ib mpox cases in one family living near Cologne, in the Rheinisch-Bergischer Kreis district. The family had two school-age children, so their school closed classrooms temporarily and switched to remote learning while officials traced contacts.

The Key Lesson: Schools Need a Plan for Both Closing and Reopening

Closing a classroom is quick, but reopening with confidence takes a good plan. Points Thai schools should care for are:

• Desks, chairs and learning materials shared by many children
• Toilets, sinks and taps used all day
• The sick room and its beds
• Nap rooms and mats in kindergarten classes
• School buses where children from many homes sit together

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 Schools

1. Pupils with a rash or fever still coming to school: likelihood medium / impact high / level high. Mitigation: screen at the gate and ask parents to keep symptomatic children home. Owner: class teacher
2. Kindergarten mats and blankets shared: likelihood high / impact high / level critical. Mitigation: individual mats and weekly washing. Owner: kindergarten teacher
3. Classrooms reopened without a deep clean: likelihood medium / impact high / level high. Mitigation: fog and wipe desks and chairs before reopening. Owner: facilities
4. No remote learning plan when a room must close: likelihood low / impact high / level medium. Mitigation: prepare an online learning system in advance. Owner: academic affairs
5. Parent panic and rumours in chat groups: likelihood medium / impact medium / level medium. Mitigation: share official information and protect the family's privacy. Owner: school leadership

Ways to Reduce Risk in Schools

1. Screen for symptoms at the gate and ask children with a rash or fever to stay home
2. Give each kindergarten child their own mat and blanket
3. Wipe desks, chairs and equipment with disinfectant every day
4. Clean toilets and taps several times a day
5. Prepare a remote learning plan in case a classroom must close
6. Fog before reopening after every closure or case
7. Communicate with parents openly and without stigma

How ULV Fogging Helps

The [World Health Disinfection disinfection service]({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]({PRODUCT}). 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
