Warts and verrucas are highly contagious skin infections that frequently circulate in environments where children and adults congregate, such as schools and leisure centres. These growths are caused by the human papillomavirus (HPV), which is resilient enough to survive on various surfaces outside the human body for short periods. In settings like swimming pools and school changing rooms, the combination of bare skin, moisture, and shared surfaces creates an ideal pathway for the virus to move from one person to another.

How the virus spreads in communal environments
The virus that causes warts and verrucas is primarily spread through direct skin-to-skin contact or indirect contact with contaminated surfaces. In schools, children often come into close physical contact during play, sports, or while sharing equipment, which allows the virus to transfer easily between hands. Indirect spread occurs when an infected person sheds microscopic skin cells containing the virus onto objects like desks, PE mats, or towels. The NHS states that you can catch warts from other people and from contaminated objects or surfaces. Because the virus can survive in damp environments, shared facilities like school showers or changing room floors are particularly effective at facilitating this indirect transmission.
The risk of verruca transmission in swimming pools
Swimming pools are one of the most common places for the spread of verrucas because the skin on the soles of the feet becomes soft and more permeable when wet. When someone with a verruca walks barefoot on a wet poolside or in a communal shower, they can leave behind viral particles in the puddles or on the damp tiles. The NICE guidelines highlight that communal showers and changing rooms are major sites for the transmission of plantar warts (verrucas). The abrasive surface of poolside tiles can also cause tiny, often invisible, scratches on the soles of the feet, providing a direct entry point for the virus to infect the skin of the next person who walks by.
Factors that increase the likelihood of contagion
Not everyone who comes into contact with the virus will develop a wart or verruca, as the risk of infection depends on several factors. The integrity of the skin barrier is a major factor; individuals with eczema, dry skin, or small cuts are more likely to become infected because the virus can bypass the outer protective layer of the skin more easily. The strength of an individual’s immune system also plays a role in whether the body can successfully fight off the virus before a growth forms. Children are generally more susceptible than adults because their immune systems are still developing and have not yet built up immunity to the many different strains of HPV.
Preventing the spread in schools and clubs
If a child has a wart or verruca, they do not need to be excluded from school or physical education, but certain precautions should be taken to protect others. For warts on the hands, children should be encouraged to wash their hands regularly and avoid biting their nails or picking at the growth, as this can release more viral particles. For verrucas, the use of a waterproof plaster or a “verruca sock” during swimming and PE can act as a physical barrier to prevent the virus from shedding onto shared floors. It is also important for children not to share personal items like towels, socks, or shoes with their peers, as these items can easily harbour and transfer the virus.
Environmental hygiene in public facilities
Public swimming pools and school facilities follow specific cleaning protocols to manage the risk of various infections, including those caused by fungi and viruses. Regular disinfection of floors and communal surfaces helps to reduce the viral load in these areas. However, because these spaces are used by hundreds of people daily, it is impossible to guarantee they are entirely free of the virus at all times. This is why personal protective measures, such as wearing flip-flops in changing rooms and showers, remain the most effective way for individuals to reduce their own risk of infection while using these facilities.
Conclusion
Warts and verrucas are a common part of life in UK schools and swimming pools due to the resilient nature of the HPV virus. While they are highly contagious in damp and crowded environments, the risk can be significantly managed through simple hygiene practices and the use of protective barriers. Maintaining skin integrity and avoiding barefoot contact in communal areas are the best ways to stay protected. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Should my child stay home from school if they have a wart?
No, there is no need for children to stay home; they should simply be encouraged to follow good hygiene and cover the wart if it is in a location likely to touch others.
Does chlorine in the pool kill the virus?
Chlorine is effective at killing many pathogens in the water, but it may not immediately eliminate viral particles sitting on wet surfaces like tiles or benches.
Can you get warts from sharing a computer keyboard at school?
It is possible if an infected person has shed viral particles onto the keys, which is why regular handwashing is encouraged in schools.
Are verruca socks 100% effective?
Verruca socks provide a strong physical barrier, but they must be fitted correctly and kept in good condition to be most effective.
Why do some children get many warts while others get none?
Susceptibility varies based on individual immune responses and the presence of minor skin breaks or conditions like eczema.
Can the virus spread through shared PE mats?
Yes, damp PE mats can harbour the virus, so covering any exposed warts or verrucas during these activities is a sensible precaution.
Is it safe to share a towel if we are in the same family?
It is best not to share towels, as this is one of the most direct ways to transfer the virus between family members.
