The True Story: A Cluster at a Military Camp in Chonburi

The Weekly Epidemiological Surveillance Report outbreak summary for week 9 of 2026 (published 31 March 2026) recorded a cluster of probable influenza cases at a military camp in Chonburi province.

Thailand's Department of Disease Control has said for years that schools, prisons and military camps are where clusters often occur, because they are closed spaces where people live closely together.

The Key Lesson: Eating, Sleeping and Training Together Spreads Flu Through a Whole Company

Military camps, police academies and training centres with shared dormitories have similar risks. Points to watch are:

• Shared dormitories with dozens of beds side by side
• Mess halls where hundreds eat at once
• Shared shower rooms used in shifts
• Training equipment passed hand to hand
• A culture of toughing it out that discourages reporting illness

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 Military Camps and Shared Dormitories

1. Recruits afraid to report illness: likelihood high / impact high / level critical. Mitigation: make clear there is no penalty for reporting sick and check fever each morning. Owner: company commander
2. No isolation room: likelihood high / impact high / level critical. Mitigation: set up isolation in the camp infirmary before the season. Owner: camp medical unit
3. Dormitory beds close together: likelihood high / impact medium / level high. Mitigation: space beds and alternate head and foot. Owner: admin officer
4. Mess halls and showers not cleaned on a schedule: likelihood high / impact medium / level high. Mitigation: wipe tables after every meal and clean showers several times a day. Owner: duty roster
5. Dormitories not disinfected after cases: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat dormitories at once after a cluster. Owner: camp medical unit

Ways to Reduce Flu Risk in Camps and Dormitories

1. Check for fever every morning before training
2. Allow sick reports with no penalty
3. Isolate the sick in the infirmary
4. Space beds and alternate head and foot
5. Install handwashing points at mess halls and showers
6. Vaccinate new recruits before the season
7. Fog and ozone-treat dormitories after cases

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: Was there really a flu cluster at a Thai military camp in 2026? A: The week-9 2026 surveillance report recorded a cluster of probable flu at a military camp in Chonburi.

Q: Why are military camps at risk? A: They are closed spaces where people eat, sleep and train closely together, which is why the DDC repeatedly names schools, prisons and camps as hotspots.

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

Prevent Flu with Disinfection Fogging and Ozone Treatment

The true story from Thailand's surveillance report shows military camps remain a risk every year. Prepared units avoid halting training because a whole company is sick. Reduce the risk with the World Health Disinfection disinfection service for mess halls, shared showers and training buildings, and the ozone treatment service for shared dormitories and isolation rooms.
