FAQ

  • Is it contagious?
    Yes—it spreads through direct skin-to-skin contact or by sharing items such as towels.
  • How long does it last?
    It may last for several months and sometimes longer, but it usually clears on its own without scarring.
  • Can adults get molluscum contagiosum?
    Yes. Although it is more common in children, adults can get it too.
  • Can it spread to other parts of the body?
    Yes. Scratching or picking the bumps can spread the virus to nearby skin.
  • Should I cover the bumps?

  • Can it come back?
    Yes. New bumps can appear while the infection is active, and some people may become infected again after it has cleared.
  • When should I see a doctor?
    If the bumps become painful, red, infected, affect the eyes or genital area, or if you are unsure of the diagnosis, you should see a healthcare professional.
