Does molluscum contagiosum go away on its own?

Yes, molluscum contagiosum usually clears on its own within 6–18 months as the immune system fights the virus. Treatment can speed resolution and reduce the risk of spreading to others.

Is molluscum contagiosum an STI?

In adults, molluscum contagiosum is commonly spread through sexual contact and is considered an STI. In children, it is typically spread through non-sexual skin contact and is not considered an STI.

How can I tell the difference between molluscum and genital warts?

Molluscum bumps are typically smooth, dome-shaped, and have a central dimple. Genital warts are usually rough, cauliflower-shaped growths. A clinician can make the distinction through visual examination.
