Molluscum Contagiosum

Molluscum contagiosum causes small, pearly, dome-shaped bumps on the skin and is spread through skin-to-skin contact. In adults, it is often sexually transmitted. The infection is harmless and usually clears on its own within 6–18 months, though treatment can speed resolution.
