Molluscum Contagiosum – Symptoms and Causes

Overview

Molluscum contagiosum is a viral skin infection that causes raised, round, and firm bumps on the skin. These bumps range in size from a pinhead to a pencil eraser and are typically painless.

However, in some cases, they may become irritated or inflamed.

The infection is caused by the molluscum contagiosum virus (MCV) and spreads through:

• Direct skin-to-skin contact
• Touching contaminated objects, such as towels or toys
• Scratching or injuring existing bumps, which can spread the virus to nearby skin

While children commonly develop this condition, adults can also be affected. Among adults, sexual contact is a common transmission route. People with weakened immune systems are at a higher risk of infection.

Molluscum contagiosum is self-limiting, meaning it typically clears up on its own within 6 months to 2 years without treatment. The virus specifically affects the outer layer of the skin, creating the distinctive raised bumps that characterize the condition.
