Molluscum is a common skin problem with small, harmless raised spots. The spots can stay on the body for a few weeks, several months or more than a year. It is caused by the Molluscum Contagiosum Virus (MCV). This virus only lives in humans. Molluscum is contagious and can be spread from person to person or to different areas in the same person. It can also be spread by children sharing baths or pools through bath toys and towels. Usually it does not need any treatment. Good personal hygiene can help prevent it spreading.
