The True Story: A First Case and Contact Tracing

On 15 June 2022, Luxembourg diagnosed its first mpox case, announced the following day. The patient was treated at the Centre Hospitalier de Luxembourg (CHL), and officials said the condition was excellent.

The health ministry began contact tracing at once. In a city where many people cross borders to work daily, knowing where a patient has been speeds up the investigation.

The Key Lesson: Lift Buttons and Turnstiles Are Touched Thousands of Times a Day

Office towers in Silom, Sathorn and Asok host thousands of staff and visitors daily. Points to watch are:

• Lift buttons inside and out tapped all day
• Turnstiles and card readers everyone passes
• Lift and stair rails held by hands
• Visitor desks where pens and passes change hands
• Shared restrooms on each floor in heavy use

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 Office Towers

1. Lift buttons wiped only once a day: likelihood high / impact low / level medium. Mitigation: wipe every two hours at peak times. Owner: building head housekeeper
2. Visitor passes reused without wiping: likelihood high / impact low / level medium. Mitigation: wipe passes on every return. Owner: receptionist
3. Turnstiles and card readers not wiped: likelihood high / impact low / level medium. Mitigation: wipe on a schedule. Owner: building housekeeper
4. No sanitiser in lobbies or at lifts: likelihood medium / impact low / level low. Mitigation: install sanitiser at key points. Owner: juristic person
5. No building-wide disinfection of common areas: likelihood medium / impact medium / level medium. Mitigation: fog lobbies and lift halls on a schedule. Owner: building manager

Ways to Reduce Risk in Office Towers

1. Wipe lift buttons every two hours at peak
2. Wipe lift rails on a schedule
3. Wipe turnstiles and readers on a schedule
4. Wipe visitor passes on every return
5. Install sanitiser in lobbies and at lifts
6. Clean shared restrooms on a schedule
7. Fog lobbies and lift halls out of hours

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
