What is "molluscum contagiosum"

n. (context medicine pathology English) A viral infection of the skin or (occasionally) mucous membranes, caused by (taxlink Molluscum contagiosum virus species noshow=1) (MCV), a DNA poxvirus.

n. a virus disease of the skin marked by round white swellings; transmitted from person to person (most often in children or in adults with impaired immune function)

Molluscum contagiosum (MC) is a viral infection of the skin or occasionally of the mucous membranes, sometimes called water warts. It is caused by a DNA poxvirus called the molluscum contagiosum virus (MCV). MCV has no nonhuman-animal reservoir (infecting primarily humans, though equids can rarely be infected). The virus that causes molluscum contagiosum is spread from person to person by touching the affected skin. The virus may also be spread by touching a surface with the virus on it, such as a towel, clothing, or toys.

Four types of MCV are known, MCV-1 to -4; MCV-1 is the most prevalent and MCV-2 is seen usually in adults. This common viral disease has a higher incidence in children, sexually active adults, and those who are immunodeficient. Molluscum contagiosum is most common in children aged one to 11 years old. MC can affect any area of the skin, but is most common on the trunk of the body, arms, groin, and legs. Some evidence indicates molluscum infections have been on the rise globally since 1966, but these infections are not routinely monitored because they are seldom serious and routinely disappear without treatment. Molluscum contagiosum is contagious until the bumps are gone. Some growths may remain for up to 4 years if not treated.
