Some investigations report that spread of molluscum contagiosum is increased in swimming pools. However, it has not been proved how or under what circumstances swimming pools might increase spread of the virus. Activities related to swimming might be the cause. For example, the virus might spread from one person to another if they share a towel or toys. More research is needed to understand if and for how long the molluscum virus can live in swimming pool water and if such water can infect swimmers.
If you notice bumps on a child’s skin, it is reasonable to inform the child’s parents and to request a doctor’s note. Only a healthcare professional can diagnose molluscum contagiosum because there are many other causes of growths on the skin, both infectious and non-infectious.
Although there has been only one reported case of healthcare provider-to-patient transmission of molluscum contagiosum, if an employee who comes in physical contact with clients regularly, such as an aesthetician or health care provider, is diagnosed with molluscum contagiosum by a health care professional, it would be reasonable to require that he/she cover visible lesions with a watertight dressing while at work. Otherwise, no special precautions are needed.
