The True Story: Canada's First Clade Ib Case

On 22 November 2024, Manitoba, Canada confirmed the country's first case of clade Ib mpox. It was travel-related and linked to the outbreak in central and eastern Africa.

Public health said there was no evidence of further transmission, and advised that high-risk close contacts be offered post-exposure vaccination, ideally within four days. Those closest to a patient are usually household members and carers.

The Key Lesson: Home Caregivers Are in the Closest Contact

Home carers for patients and older people in Thailand, both relatives and hired carers, bathe patients, change linen and dress wounds. Points to watch are:

• Dressing wounds and applying creams with direct skin contact
• Patients' sheets and clothes that need changing and washing daily
• The household bathroom shared by the patient and family
• Carers who visit several homes and may carry germs between them
• The days after a family member returns from travel when symptoms should be watched

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 Home Caregivers

1. Carer dresses wounds without gloves: likelihood high / impact high / level critical. Mitigation: wear gloves and long sleeves every time and wash hands after removing them. Owner: main carer
2. Patient's laundry washed with the household's: likelihood high / impact medium / level high. Mitigation: separate basket, no shaking, hot wash. Owner: main carer
3. High-risk contacts unaware of post-exposure vaccination: likelihood medium / impact high / level high. Mitigation: contact public health as soon as there is a case at home. Owner: head of household
4. Shared bathroom not wiped: likelihood high / impact medium / level high. Mitigation: wipe touch points after every use by the patient. Owner: main carer
5. Hired carer visits several homes in a day: likelihood medium / impact medium / level medium. Mitigation: change clothes and wash hands between homes, with clear agency guidance. Owner: care agency

Ways to Reduce Risk for Home Caregivers

1. Wear gloves whenever dressing wounds or changing linen
2. Give the patient a separate room or corner where possible
3. Wash the patient's laundry separately in hot water, without shaking
4. Wipe the bathroom and handles after the patient uses them
5. Ask public health about post-exposure vaccination quickly
6. Watch your own symptoms for 21 days after exposure
7. Fog the home after the patient's isolation ends

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
