Molluscum contagiosum is caused by the molluscum virus. It can start after you come in contact with the virus. You may come in contact with the virus by skin to skin contact with an infected person. The virus can also pass through shared items like towels or wrestling mats.
The virus can also spread from one part of a person's body to another area.
