Where Real Patients Went First

Look at the documented mpox cases in Thailand and a pattern appears: patients went to ordinary healthcare facilities before anyone knew what they had.

• August 2022. Thailand's first female case, aged 22, developed a fever on 29 July and a rash on 30 July. She went to a hospital in Samut Prakan on 3 August, was confirmed on 4 August, and was then transferred to the Bamrasnaradura Institute. Source: Bangkok Biznews, 5 Aug 2022
• August 2024. Thailand's first clade Ib patient was admitted to a private hospital in Bangkok on 15 August 2024.

Between the moment a patient walks in and the moment a result is confirmed, that patient has already sat in the waiting room, used the restroom, lain on an exam bed and touched many surfaces.

Why Clinics Cannot Tell at First Glance

On 3 November 2026, Thailand's Department of Disease Control (DDC) reported 470 mpox cases and 3 deaths in 2026, and explained that mpox lesions can resemble herpes, chickenpox or other skin infections, so looking at a rash or a photo alone cannot confirm the disease. Source: Hfocus, 3 Nov 2026

The DDC says the main confirmatory test is PCR on a lesion sample, not a routine blood test, and that patients whose symptoms persist or change after a first test should return for further assessment or repeat sampling.

That means dermatology clinics, general practices, specialist clinics and outpatient departments may already have examined mpox patients without anyone knowing on the day.

High-Risk Areas in Clinics and Hospitals

The DDC lists direct contact with lesions, close contact and items contaminated with bodily fluids or scabs as routes of spread. In a healthcare setting, priority areas include:

• Exam beds and bed covers, in direct contact with patients' skin.
• Waiting room seats, especially fabric-covered chairs.
• Patient restrooms: taps, flush handles and door handles.
• Registration and payment counters: pens and card terminals.
• Procedure rooms: skin-contact equipment, drapes and privacy curtains.
• Reusable towels and linen, which need separate handling.

The Risks Healthcare Settings Face

• Staff infection at work, particularly when staff do not wear protective equipment because they do not yet know the diagnosis.
• The next patient touching a contaminated surface.
• Vulnerable people in the waiting room. DDC Deputy Director-General Dr. Direk Khampaen said people with weakened immunity, pregnant women and young children need closer monitoring, and these are exactly the people who fill clinic waiting rooms.
• Partial service shutdowns after a confirmed result.
• Loss of patient confidence if the response looks unprofessional.

Common Mistakes

• Using the same exam bed cover for several patients.
• Wiping beds with alcohol and reusing them immediately, without the contact time the product label requires.
• Shaking used linen, instead of bagging it without shaking as the US CDC advises. Source: US CDC
• Dry sweeping exam rooms, which the CDC recommends avoiding.
• No separate screening point, so patients with fever and rash sit with everyone else.

Practical Steps for Clinics

1. Screen at the door. Ask about fever, rash, blisters and risk exposure within 21 days, which the DDC asks patients to disclose.
2. Separate the waiting area for people with fever plus rash, provide well-fitting masks and cover lesions where possible.
3. Staff wear protective equipment in line with facility and public health guidance.
4. Change bed covers or paper rolls for every patient.
5. Disinfect surfaces after each patient with a product labeled to kill viruses, following the label's contact time.
6. Handle linen and infectious waste properly: separate bags, tied securely, never shaken.
7. Disinfect the whole area on a schedule, and immediately when notified that a confirmed patient visited.
8. Work with public health officials on contact tracing.

Why Healthcare Facilities Choose Chemgene and WHD's Service

The mpox virus is an enveloped virus, the type that suitable disinfectants can inactivate when used correctly and given the full contact time.

CHEMGENE HLD4H is a concentrated disinfectant imported from the United Kingdom. According to our service page, it is endorsed by Mahidol University and NHS England and references testing to the European virucidal standard EN 14476. WHD's disinfection service has worked in a Bangkok hospital among other sites. See the disinfection service

Ten reasons it suits clinics and hospitals:

1. A disinfectant used in healthcare settings, endorsed by NHS England and Mahidol University per product information.
2. References EN 14476 virucidal testing.
3. Treatment after closing time, without affecting patient hours.
4. Fast return to use. Under our service process, areas can be used about 30 minutes after spraying.
5. ULV mist reaches hidden spots, under beds, behind cabinets and around privacy curtains.
6. Covers exam rooms, waiting rooms, restrooms and procedure rooms.
7. Suitable around electronics, as stated on our service page.
8. Emergency call-outs when you are notified of a confirmed patient who visited.
9. Tax invoices and 3% withholding tax for juristic persons.
10. More than five years of experience.

Before and After

Before

• Patients with fever and rash wait alongside everyone else.
• Beds are wiped in a rush between appointments.
• When a confirmed result comes in, nobody is sure which areas to clean.
• Staff worry about their own safety.

After

• A screening point and separate waiting area are in place.
• Surfaces are disinfected after every patient, with the full contact time.
• Whole areas are disinfected on schedule and after incidents.
• Staff and patients feel more confident.

What to Keep in Mind

Disinfection is one part of a healthcare facility's infection prevention system. It does not replace screening, personal protective equipment, hand hygiene or public health guidance. Facilities should follow their own infection control policies and Ministry of Public Health guidance first.

Frequently Asked Questions

We were told a patient from yesterday has mpox. What now? Coordinate with public health officials on contact tracing, clean and disinfect the areas the patient used, and consider professional disinfection of the whole area.

Do we have to close the clinic? Usually not for long. Under WHD's service process, areas can be used about 30 minutes after spraying, and we can work after hours.

Can a blood test confirm mpox? The DDC says routine blood tests are not confirmatory. The main test is PCR from a lesion sample.

How should exam bed linen be handled? Change it for every patient, bag it without shaking, and launder it according to facility procedures.

A Prepared Facility Is the First Line of Protection

Real cases in Thailand show that mpox patients often walk into ordinary healthcare facilities before a diagnosis is confirmed. Clinics and hospitals with proper screening, cleaning and disinfection protect their staff, their other patients and the trust of the people they serve.

World Health Disinfection provides CHEMGENE HLD4H disinfection for clinics, hospitals, health check centers and healthcare facilities of every size.
