Top 10 Foggers and Disinfectants for Marathons and Triathlon Events: Lessons from Norovirus After the Laugarvatn Triathlon, Iceland (2025)
About 40 people at an Icelandic triathlon reported vomiting and diarrhoea, and norovirus was confirmed, with the source, water, food or surfaces, still unknown. What should Thai race organisers prepare?
The Real Story from the News: Water, Food or Surfaces?
Iceland's Directorate of Health reported on 10 July 2025 that after the 5 July Laugarvatn triathlon, about 40 people reported vomiting and diarrhoea, 22 of them officially.
Norovirus was confirmed in all five samples, but it was unclear whether it came from the lake, food or surfaces, and at least two people who didn't swim also fell ill.
Why Choosing the Right Equipment Matters
Races have portable toilets, water stations, finish-line food and thousands of people in one place. With sources unclear, organisers must cover every risk point, from handwashing to toilets and food areas, following CDC norovirus guidance.

Prefer Not to Do It Yourself? Use a Professional Service
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Frequently Asked Questions
Q: Are outdoor events at risk of norovirus? A: Yes; Iceland saw illness even in non-swimmers, so toilets, food and handwashing all need attention.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Health References
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
Summary
Laugarvatn shows one sports event can make dozens ill. Organisers with complete hygiene systems make race day a good memory.
