The True Story: Preventing Before the Virus Arrives

Ecuadorian outlet Primicias reported on 16 December 2025 that Ecuador's Ministry of Public Health (MSP) recommended masks for patients, staff and visitors in both public and private hospitals to prevent influenza A(H3N2) subclade K.

The report said Ecuador had not yet found subclade K cases, but neighbouring Peru and Mexico had confirmed them, making this a preparatory step ahead of year-end travel.

The Key Lesson: Small Clinics Have One Waiting Room Everyone Shares

Thai private clinics have small waiting rooms, see every condition in one room and open late. Points to watch are:

• Small waiting rooms with feverish patients beside check-up visitors
• Dispensing counters where people wait close
• One exam room used all day
• Doctors and nurses with no cover when ill
• Patients back from abroad not mentioning travel

How Flu Spreads

According to the World Health Organization, seasonal influenza spreads easily where people gather, such as schools and nursing homes. It spreads through droplets when people cough or sneeze, and through hands that touch contaminated surfaces and then the eyes, nose or mouth. Most people recover within a week, but young children, older adults, pregnant women and people with chronic illness are at risk of severe disease. Influenza is an enveloped virus, which suitable disinfectants can inactivate.

Risk Register for Private Clinics

1. Feverish patients sit with others: likelihood high / impact high / level critical. Mitigation: masks and separate seating. Owner: receptionist
2. Travel history not asked: likelihood medium / impact medium / level medium. Mitigation: add travel questions to screening forms. Owner: receptionist
3. Exam room not wiped between patients: likelihood high / impact medium / level high. Mitigation: wipe bed and desk after feverish patients. Owner: nursing assistant
4. Doctors and nurses fall ill: likelihood medium / impact high / level high. Mitigation: vaccinate and mask all day. Owner: clinic owner
5. Clinic not disinfected at day's end: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat exam rooms after closing. Owner: clinic owner

Ways to Reduce Flu Risk in Private Clinics

1. Have everyone mask in outbreaks
2. Ask travel history on screening forms
3. Seat feverish patients apart
4. Wipe exam beds after feverish patients
5. Vaccinate staff
6. Ventilate waiting rooms
7. Fog and ozone-treat exam rooms after closing

How ULV Disinfection 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 reach.

• Whole-area coverage without relying on wiping spot by spot
• Quick return to use, typically about 30 minutes after fogging
• Uses Chemgene HLD4H, which meets EN 14476 for virucidal activity according to the product page
• The team wears full protective equipment, so owners and staff do not take the risk themselves
• Report and photos after the job for customers, management or authorities
• Tax invoice with 3% withholding tax for companies and agencies

Ozone Treatment for Closed Rooms and Stuffy Spaces

The World Health Disinfection ozone treatment service uses machines that generate ozone gas from oxygen in the air. It suits closed rooms such as meeting rooms, bedrooms, classrooms, sick bays and vans, helping reduce germs in the air and on surfaces and removing stale odours. Ozone breaks back down into oxygen after treatment, leaving no residue.

• Works alongside disinfection fogging: spray or wipe surfaces first, then use ozone for the air and corners of closed rooms
• No people or pets in the room during treatment: the team seals the room and runs a timer
• Ventilate after treatment before normal use resumes
• Machines tested by Intertek, according to WHD's service page
• Ideal after someone has been ill, such as recovered patients' rooms, shared bedrooms and shuttle vans
