The True Story: Warning Before the Virus Arrives

MercoPress reported on 15 December 2025 that Peru's Health Ministry (Minsa) issued nationwide Epidemiological Alert No. 008-2025 as a preventive measure against the entry and spread of influenza A(H3N2) subclade K and measles, citing increased international travel and large year-end holiday crowds.

Peru's National Institute of Health had found no subclade K cases in the country and rated the risk mild to moderate. Minsa asked travellers returning from Europe or the US to watch for respiratory symptoms and give their travel history when seeking care, while Health Minister Luis Quiroz urged at-risk groups to keep vaccinations up to date.

The Key Lesson: Airports Are the Gate Every Continent's Viruses Pass Through

Thai airport lounges and terminals receive tens of thousands of passengers a day from Europe, the US and Asia in high season. Points to watch are:

• Lounges where passengers wait for hours
• Lounge buffets with shared tongs
• Shower rooms used one after another
• Trolleys and self check-in kiosks
• Prayer and rest rooms that are enclosed

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 Airport Lounges and Terminals

1. Sick passengers wait in lounges: likelihood high / impact medium / level high. Mitigation: masks and gel in every zone. Owner: lounge manager
2. Shared buffet tongs: likelihood high / impact medium / level high. Mitigation: change tongs in rounds or serve plated. Owner: food team
3. Shower rooms used back to back: likelihood high / impact medium / level high. Mitigation: clean after every user. Owner: lounge housekeeping
4. Shared kiosks and trolleys: likelihood high / impact medium / level high. Mitigation: wipe screens and handles in rounds. Owner: facilities
5. Lounge not deep-cleaned: likelihood medium / impact medium / level medium. Mitigation: fog and ozone-treat rest rooms in quiet periods. Owner: lounge manager

Ways to Reduce Flu Risk in Airport Lounges

1. Provide masks and gel in every zone
2. Change buffet tongs in rounds
3. Clean shower rooms after every user
4. Wipe kiosks and trolleys
5. Ventilate rest rooms
6. Inform symptomatic passengers where to get help
7. Fog and ozone-treat rest rooms in quiet periods

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
