The skin lesion as marked by a red arrow in the picture above represents Molluscum contagiosum.
Molluscum contagiosum (MC)
- It 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 only humans).
- There are four types of MCV, MCV-1 to -4; MCV-1 is the most prevalent and MCV-2 is seen usually in adults.
- The virus that causes molluscum 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.
- Molluscum can be spread from one person to another by sexual contact.
- This common viral disease has a higher incidence in children, sexually active adults, and those who are immunodeficient, and the infection is most common in children aged one to ten years old.
- MC can affect any area of the skin but is most common on the trunk of the body, arms, groin, and legs.
- It is spread through direct contact or shared items such as clothing or towel.
