It also included the warning:

"Urgent warning!! Be careful when using toilet seats in public restrooms because mpox is currently spreading. If possible, avoid shared toilets altogether because this disease is very dangerous. #AvoidPublicToiletsIfPossible"

Can you really catch mpox from a public toilet seat?

Suchada Jiamsiri, director of the AIDS and Sexually Transmitted Infections Division at Thailand's Department of Disease Control, told Thai PBS Verify that scientific studies on surface contamination are typically conducted in homes, accommodation or environments where infected individuals have stayed for some time. The virus can be detected on various surfaces, including toilet bowls and taps.

"In the case of public restrooms, we do not know whether a person with mpox has actually used the facility. Therefore, portraying public toilets as a particularly dangerous source of infection may cause unnecessary alarm. Risks should be assessed according to the specific setting and the likelihood of exposure to an infected individual," she said.

For the general public, Ms Suchada said there was little reason for concern.

"There is no need to be overly worried because patients are not all sharing the same public restroom. From a disease prevention and control perspective, this is not considered a major concern. It is different from toilets within a patient's home, which should be thoroughly cleaned after recovery," she said.

Although the virus may be detected on surfaces, touching a contaminated surface does not automatically result in infection, particularly when the skin is intact. The likelihood of infection through surfaces in an ordinary public restroom is extremely low because viable virus would need to remain present, such as fresh fluid from a lesion contaminating a toilet seat, a scenario experts say is unlikely in most public facilities.

For those concerned about hygiene, she recommended using alcohol-based disinfectants to wipe hard surfaces such as toilet seats and flush buttons. The mpox virus is relatively easy to inactivate with alcohol. For hand hygiene, washing with soap and water is considered sufficient.

She added that how long the virus survives on surfaces depends on environmental conditions including sunlight, temperature, humidity and whether the surface remains dry. While survival times vary, wiping surfaces with alcohol may provide reassurance. Nevertheless, she said public restrooms are generally not something that should cause significant concern.

Thai PBS Verify also interviewed Dr Anan Jongkaewwattana, who said that if a person with mpox used a toilet and lesions came into contact with the seat, viral contamination could occur. However, the next user would face only a very small risk of infection if their skin remained intact.

"The skin on the buttocks and thighs is relatively thick and consists of multiple layers. It is not a mucous membrane or delicate tissue through which the virus can easily enter the body. However, if there are scratches or open wounds, infection becomes more possible," he said.

He added that infection could theoretically occur if someone touched a contaminated toilet seat and then touched their eyes, nose or mouth, areas where the virus can enter more easily through mucous membranes.

Laboratory tests have detected viral material on surfaces for several hours using PCR methods. However, there is currently no evidence confirming that virus detected two hours later remains as infectious as virus freshly shed from a patient. Exposure to air, humidity and environmental conditions may reduce infectivity.

Overall, he said transmission from a public toilet seat is highly unlikely unless the exposed skin has cuts or wounds.

Thai PBS Verify also consulted Emeritus Professor Amorn Leelarasamee, an infectious disease specialist, who noted that mpox cases are increasing in Thailand. He stressed that the disease is not transmitted solely through sexual contact but can also spread through direct physical contact, including contact with lesions on the buttocks, hands or mouth.

"If it is necessary to use a public restroom, check that it is clean before sitting down. If alcohol spray is available, disinfect the seat first or use a toilet-seat cover. People should also ensure there are no open wounds on the buttocks or hands. Any cuts should be covered with a plaster. After using the restroom, wash thoroughly with soap and water and use alcohol gel to clean your hands to reduce the risk of infection," he said.

He explained that the virus has difficulty penetrating healthy skin. However, women should take particular care regarding the vaginal area, while men should be mindful of the urethra and anal area, especially if there are wounds or exposed mucous membranes that could provide an entry point for infection.

He added that mpox is spread primarily through contact, making personal hygiene and awareness of symptoms important when using public facilities.

Mpox situation in Thailand

According to Thailand's Department of Disease Control, mpox continues to circulate in the country. As of Oct 31, 2026, Thailand had recorded 470 cumulative cases and three deaths since the start of the year, according to a report issued on Nov 3, 2026.

Surveillance data released on Nov 9, 2026, showed that the previously dominant Clade IIb strain, which drove the outbreak from 2022 onwards, has gradually declined in proportion. Meanwhile, Clade Ib has increased since mid-2026 and has become the dominant strain in Thailand. The Department of Disease Control said the Clade Ib strain has a fatality rate of less than 0.5%.

However, infected patients can still develop severe symptoms or complications, particularly those with weakened immune systems or underlying medical conditions.

Symptoms to watch for

Information published by the Department of Disease Control on Nov 9, 2026, noted that mpox symptoms can vary and may not initially present with obvious skin lesions.

Symptoms may include:

• Fever, headache and muscle aches
• Swollen lymph nodes
• Sore throat or mouth ulcers
• Rashes, blisters or pus-filled lesions
• Lesions around the genital or anal area
• Anal pain or inflammation of mucous membranes

Some patients may experience symptoms resembling tonsillitis or abscesses around the buttocks before developing visible rashes or lesions.

How is mpox transmitted?

Mpox is not transmitted only through sexual activity. It can also spread through:

• Direct contact with the skin or lesions of an infected person
• Close contact with bodily fluids or contaminated materials
• Sharing clothing, towels or bedding with an infected person
• Prolonged close contact, including sexual contact, with an infected person

The Thai Department of Disease Control emphasised that the disease is not easily spread through casual daily interactions, such as simply passing by or being near an infected person without close physical contact.
