Molluscum are small bumps caused by a superficial viral infection. They are very common, especially in kids, often spreading by skin to skin contact or by contaminated towels, gym equipment, clothing etc. Molluscum are not harmful or dangerous, and typically do not cause any symptoms. They typically present as small bumps with a central umbilication.
In healthy patients, molluscum infection is self-limited and typically self-resolves within months to one year on average. If you are immunocompromised, these bumps may be bigger than usual or may last longer.
