The True Story: Quick Detection, Step-by-Step Response, No Further Spread

In November 2024, San Mateo County Health in California dealt with the first clade I mpox case found in the United States. The infection was acquired through travel and linked to the ongoing outbreak in Central and Eastern Africa. Communicable disease investigators found the case through surveillance and information from local health care providers, then worked with CDC and the California Department of Public Health to monitor the patient, trace contacts and test specimens. The result: no secondary cases or further spread were found. The work was published in CDC's MMWR on 13 February 2025.

The Key Lesson: Speed and Clear Steps Are What Matter

This case shows that with a clear plan and immediate action, spread can be stopped from the very first case. SME businesses such as shops, restaurants, small offices and small factories often have no outbreak response plan. Things to prepare are:

• A person in charge who decides when an employee or customer is ill
• A contact list, such as the 1422 hotline, the nearest hospital and a disinfection company
• Records of attendance and shifts that help public health agencies trace contacts
• Emergency cleaning steps after a patient has used the premises
• Messages for staff and customers prepared in advance

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.

A 7-Step Rapid Response Plan for SMEs

1. Name a person in charge, and a deputy, for infectious disease incidents
2. Have employees with symptoms stop work immediately and advise them to see a doctor
3. Keep shift records and customer appointments to help trace contacts
4. Contact the 1422 hotline and follow public health advice
5. Wipe touch points immediately with disinfectant kept ready
6. Book a professional team to fog the areas the patient used
7. Communicate with staff and customers honestly, without revealing the patient's name

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

10 Reasons SMEs Should Have an Outbreak Response and Disinfection Plan

1. A quick response stops spread from the start
2. Small businesses cannot close for long
3. With few staff, one sick person affects the whole shop

6. Fogging can be done outside business hours
7. It will not damage stock or equipment
8. No harsh smell to bother customers
9. The shop can reopen about 30 minutes after fogging
10. It comes with a tax invoice and 3% withholding for companies
