The True Story: Virus Found in Half of Samples

Chilean outlet El Desconcierto reported on 22 June 2026 that respiratory virus positivity in Chile reached 52%, the highest of 2026, with influenza A the most common virus.

The report said paediatric beds were under pressure, and Chile's Ministry of Health (Minsal) urged at-risk groups to get flu vaccines to ease the load on hospitals during the southern hemisphere winter.

The Key Lesson: The Community's First Line Sees Patients First

Thai community health centres see sick children, older people collecting chronic-disease medicines and pregnant women at antenatal visits in one place. Points to watch are:

• Waiting seats where feverish patients sit with others
• One exam room used all day
• Few staff for many patients
• Pregnant women and older people at risk of severe illness
• Nebuliser rooms used in turn

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 Community Health Centres

1. Feverish patients sit with at-risk groups: likelihood high / impact high / level critical. Mitigation: set up screening and separate seating for fever. Owner: registered nurse
2. Exam room not wiped between patients: likelihood high / impact medium / level high. Mitigation: wipe exam bed and desk after every feverish patient. Owner: exam room staff
3. Staff fall ill: likelihood medium / impact high / level high. Mitigation: vaccinate staff and wear masks daily. Owner: centre director
4. At-risk appointments clash with fever peaks: likelihood medium / impact medium / level medium. Mitigation: separate antenatal and chronic clinic times. Owner: centre director
5. Building not disinfected at peak: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat exam rooms after hours. Owner: centre director

Ways to Reduce Flu Risk in Community Health Centres

1. Set up fever screening at the entrance
2. Separate waiting seats for fever patients
3. Hand out masks to coughing patients
4. Separate appointment times for at-risk groups
5. Wipe exam beds after every fever patient
6. Vaccinate staff and at-risk groups
7. Fog and ozone-treat exam rooms after hours

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

Before and After

Frequently Asked Questions

Q: How high did Chile's respiratory virus positivity go? A: 52%, the highest of 2026, per the 22 June 2026 report, led by influenza A.

Q: Should pregnant women get a flu vaccine? A: Thailand's DDC lists pregnant women from 4 months as a priority group; consult a doctor.

Q: Does the fogging disinfectant work on flu? A: The team uses Chemgene HLD4H, which meets EN 14476 for virucidal activity according to the product page, and influenza is an enveloped virus that suitable disinfectants can inactivate. Fogging does not replace vaccination or handwashing.

Q: Can I enter the room right after ozone treatment? A: No one should be in the room during treatment. Ventilate afterwards before normal use; the team will advise the right time for the room size.

Q: Can government agencies get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
