The True Story: A First Case Isolating at Home

On 3 August 2022, Guatemala's health ministry confirmed its first mpox case, a 31-year-old man in Guatemala City.

He isolated at home while officials traced contacts. Home isolation means families must know how to separate belongings and clean, because children in the home still go to school every day.

The Key Lesson: Children from Many Homes Sit Close Together Twice a Day

School vans pick up children from many homes on one route. Points to watch are:

• Seats and backrests where children sit close
• Rails and door handles every child holds
• Seat belts touching necks and arms
• Windows where children press their faces
• No channel for parents to report rash or fever

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 School Vans

1. Children with rash or fever still ride: likelihood medium / impact medium / level medium. Mitigation: ask parents to report and keep sick children home. Owner: van operator
2. Seats and rails not wiped: likelihood high / impact low / level medium. Mitigation: wipe after morning and evening runs. Owner: driver
3. Seat belts never cleaned: likelihood high / impact low / level medium. Mitigation: wipe belts and buckles daily. Owner: driver
4. No sanitiser on board: likelihood medium / impact low / level low. Mitigation: install sanitiser and have children use it before boarding. Owner: van operator
5. Vehicle never fully disinfected: likelihood medium / impact medium / level medium. Mitigation: fog the whole van weekly. Owner: van operator

Ways to Reduce Risk in School Vans

1. Ask parents to report when children are ill
2. Keep children home with rash or fever
3. Have children sanitise before boarding
4. Wipe seats and rails after every run
5. Wipe seat belts daily
6. Wipe inside windows daily
7. Fog the whole van weekly

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
