Yes, molluscum contagiosum is contagious. Molluscum contagiosum is transmitted by either direct person-to-person contact or through contact with contaminated objects, such as shared clothing, towels, washcloths, and toys. This route of transmission is most common in children. In adults, molluscum contagiosum is often acquired through sexual contact.

Furthermore, if an infected person touches the lesions and then touches another part of his or her body, it can cause spread to that area (known as autoinoculation).
