Real Research: How Long the Virus Lasts on Stainless Steel

Researchers at Ruhr University Bochum in Germany, led by Toni Meister and Eike Steinmann, placed mpox virus on cleaned stainless steel plates and stored them at different temperatures. The work was published in the Journal of Infectious Diseases. Source: HealthDay summary of the study

• At 22°C (room temperature), infectious virus lasted about 10 to 11 days.
• At 4°C, up to 30 days.
• At 37°C, no replicating virus was found after 6 to 7 days.
• Virus levels changed little in the first few days.
• The researchers also found that different types of disinfectant performed differently.

Most gyms in Thailand run air conditioning, so indoor temperatures sit close to the study's 22°C, and much of their equipment is iron or stainless steel touched by hundreds of members' skin every day.

The Situation in Thailand, and Who Should Pay Attention

Cases reported in the news during 2026 have mostly been working-age adults aged 25 to 40, including one linked to prolonged close skin-to-skin contact in a crowded area. Source: The Nation, 19 May 2026 That is the same age group as most gym members.

Risk Points in Gyms and Studios

• Dumbbell, barbell and machine handles made of iron or stainless steel.
• Bench and machine pads touched directly by sweaty skin.
• Shared yoga and stretching mats.
• Towels provided by the gym.
• Locker rooms, showers and saunas.
• Contact classes such as Muay Thai, martial arts and partner stretching.

The Business Risks

• Members worry and do not renew.
• Trainers in close contact with members want reassurance about their own safety.
• Cleanliness reviews are a key factor when people choose a gym.
• Emergency zone closures for cleaning at peak hours.

What Many Gyms Do, and Why It Is Not Enough

• Leaving spray bottles for members, who mostly wipe the pad and skip the handles.
• Wiping and using immediately, without the label's contact time.
• Products with no virucidal claim.
• Washing towels together without bagging them separately.
• Dry sweeping locker rooms, which the US CDC advises against. Source: US CDC

Good Practice for Gyms, Fitness Centres and Studios

1. Staff disinfect equipment on a schedule, hourly at peak times, focusing on handles and pads, with a product labeled to kill viruses and its full contact time.
2. Ask members to cover pads with their own towel and bring their own yoga mat.
3. Single-use towels, bagged for laundry without shaking.
4. Disinfect locker rooms and showers daily using wet methods.
5. Polite signage asking anyone with fever, rash or blisters to skip their workout and see a doctor, with the DDC hotline 1422.
6. In contact classes, instructors observe and politely ask about symptoms.
7. Whole-facility disinfection on a schedule after closing.

Before and After

Before

• Members wipe equipment inconsistently.
• Metal handles are never wiped.
• Towels and mats are shared.
• Members ask about cleanliness more often.

After

• Staff disinfect equipment on schedule, with full contact time.
• Locker rooms and showers disinfected daily.
• The whole facility disinfected to plan.
• Members feel confident and renew.

Frequently Asked Questions

Are gyms high-risk places? The main route is close contact with a patient, but gyms have equipment and pads touched by many people's skin, and research shows the virus can survive on stainless steel for days. Strict disinfection is sensible.

Is wiping with alcohol enough? The German study found alcohol-based disinfectants effective, while some other types performed poorly. Choose a product labeled to kill viruses and follow its contact time.

How often should we spray? It depends on member numbers. Busy gyms should have a regular schedule alongside daily equipment wiping.

What if a member reports being sick? Contact public health officials, clean and disinfect the areas they used, and keep their personal information private.
