The True Story: Three Patients, Unconnected, and None Had Been Abroad

On 17 October 2025, the California Department of Public Health (CDPH), together with the City of Long Beach and Los Angeles County, announced three unrelated cases of clade I mpox in Southern California. Crucially, none of the three had travelled abroad, pointing to person-to-person spread in the community. Earlier US clade I cases had all been linked to international travel. All three needed hospital treatment and were recovering. The state said the risk to the general public remained low and stepped up surveillance and contact tracing. One of its recommendations was to avoid sharing towels and bedding.

Why This News Matters: You Can Be Infected Without Travelling

Many earlier articles focused on travellers, but the California case shows that once a virus spreads in the community, anyone in the city may be exposed without boarding a plane. Places where people live together need to be better prepared. Condos, apartments and dormitories in Thailand's big cities have many shared areas.

• Lifts and buttons pressed by hundreds of residents every day
• Fitness rooms, pools and shared showers
• Shared laundry rooms with washing machines and folding tables used by everyone
• Lobbies, parcel rooms and banisters
• Units where a patient has stayed, when the tenant moves out

How Mpox Spreads

According to the World Health Organization, mpox spreads mainly through close contact with an infected person, including sexual contact, and through contaminated items such as towels and bedding. Using shared areas is not generally a main route, but places where fabrics and equipment are shared, such as laundry rooms and gyms, deserve special care. Mpox is an enveloped virus, which suitable disinfectants can inactivate.

What Building Juristic Persons Should Prepare

1. An infectious disease plan with clear responsibilities and steps
2. More frequent disinfection of high-touch points, such as lift buttons, door handles and banisters
3. Care for laundry rooms and gyms: wipe machines and equipment daily and put up signs against sharing towels
4. Polite communication with residents when there is news of a case, without revealing personal data
5. Coordinate with public health officials, and call 1422 in Thailand when told there is a patient in the building
6. Fog common areas on a schedule, and fog any unit where a patient stayed before a new tenant moves in

For Owners of Rental Units

• A unit where a tenant had an infectious illness should be cleaned and fogged fully before being let again
• Wash or replace curtains, pillowcases and sheets
• Fog mattresses and sofas, which cannot be washed whole
• Keep the disinfection report to show the new tenant

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
