What is Molluscum contagiosum?

Molluscum contagiosum is a common skin infection caused by a poxvirus. It spreads primarily through direct skin contact with an infected person or by touching contaminated objects, such as towels, clothing, or sports equipment. In adults, it can also spread through sexual contact, particularly when lesions appear in the genital area. Additionally, the infection can spread to other parts of the body through auto-inoculation, where scratching or touching the lesions transfers the virus.

What are the symptoms?

Molluscum contagiosum looks like small, dome-shaped, flesh-colored bumps that often have a central dimple. These painless growths are typically 2-5 mm in size and may appear on the face, trunk, arms, legs, or genital areas. In some cases, the lesions may cause mild itchiness or become inflamed.

What are the treatments?

Treatment options vary depending on the severity and location of the lesions. Many cases resolve on their own within 18 months without intervention. However, for faster resolution, treatments like cryotherapy (freezing the lesions with liquid nitrogen), topical creams (such as salicylic acid or imiquimod), or minor surgical procedures like curettage (scraping off the lesions) can be effective. Preventive measures, including avoiding shared personal items and maintaining good hygiene, can help reduce the risk of spreading or contracting the infection.
