Molluscum contagiosum is caused by a virus that is a member of the poxvirus family. This virus is called molluscipoxvirus molluscum contagiosum.
It is frequently seen on the face, neck, arm pit, arms, and hands but may occur anywhere on the body except the palms and soles. Occasionly, it is seen on the genitals.
Early lesions on the genitalia may be mistaken for herpes or warts but, unlike herpes, these lesions are painless.
The virus is contagious through direct contact, as seen in children, but may spread by sexual contact. It can spread on a person from lesions to adjacent normal skin areas.
It is not herpes.
