Molluscum Contagiosum: Causes, Spread, and What Actually Works

When your child or partner develops tiny, flesh-colored bumps on their skin—often round, with a dimple in the middle—it’s likely molluscum contagiosum, a harmless but contagious viral skin infection caused by the molluscum contagiosum virus. Also known as water warts, it’s not dangerous, but it can spread easily and last for months if left alone. This isn’t acne, it’s not an allergy, and it’s not caused by poor hygiene. It’s a virus that loves warm, moist skin and thrives in places where people touch each other—like swimming pools, shared towels, or during rough play.

It’s most common in kids under 10, but adults get it too, especially if they have weakened immune systems or engage in close skin contact, like wrestlers or sexual partners. The bumps usually show up on the face, arms, legs, or groin. They don’t hurt, but they can itch. Scratching them spreads the virus to other parts of the body or to other people. That’s why keeping nails short and avoiding shared towels matters more than any cream you buy at the store.

Many parents panic when they see these bumps, but most cases clear up on their own within 6 to 12 months. There’s no magic cure, and aggressive treatments like freezing or scraping often cause more irritation than help. What actually works? Patience, avoiding scratching, and keeping the skin clean and dry. Some topical treatments, like tea tree oil or iodine, have anecdotal support, but nothing beats time and good hygiene. If the bumps are spreading fast, causing discomfort, or don’t go away after a year, talk to a doctor—there are safe, gentle options available.

What you’ll find below are real, practical guides from people who’ve dealt with this—whether it’s how to stop the spread in a household, what over-the-counter options actually help, or how to tell if it’s something else entirely. No fluff. No fear-mongering. Just what works, what doesn’t, and what you need to know to keep your family healthy.
