The True Story: Flu Before the Big Exam

Malaysia's The Star reported on 13 October 2025 that about 6,000 students had influenza and clusters in week 40 rose to 97 from 14 the week before, with Selangor having the most at 43.

Mohd Azam Ahmad, Director-General of Education, told schools to follow health ministry guidelines, while the national SPM exams were due to start on 3 November, requiring plans for students who fall ill during exams.

The Key Lesson: Candidates Sit for Hours in Closed Rooms

Thai exam venues host thousands of candidates for university entrance, civil service and licensing exams. Points to watch are:

• Closed AC exam rooms with rows of seats for hours
• Sick candidates who must sit with no make-up round
• Entrances and ID checks with packed queues
• Toilets between papers
• Invigilators walking past every desk

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 Exam Venues and Test Centres

1. Sick candidates sit with others: likelihood high / impact high / level critical. Mitigation: separate exam rooms for symptomatic candidates. Owner: venue director
2. Closed AC rooms for hours: likelihood high / impact medium / level high. Mitigation: air rooms between papers. Owner: building manager
3. Crowded ID check queues: likelihood high / impact medium / level high. Mitigation: staggered entry and more check points. Owner: central committee
4. Invigilators fall ill: likelihood medium / impact high / level high. Mitigation: backup invigilators. Owner: venue director
5. Rooms not disinfected before exams: likelihood medium / impact high / level high. Mitigation: fog and ozone-treat rooms before exam day. Owner: building manager

Ways to Reduce Flu Risk at Exam Venues

1. Provide separate rooms for symptomatic candidates
2. Open more ID check points
3. Place hand gel at exam room doors
4. Ask symptomatic candidates to mask
5. Air rooms between papers
6. Keep backup invigilators
7. Fog and ozone-treat rooms before exam day

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
