Causes and symptoms of Molluscum contagiosum

Molluscum Contagiosum is a relatively common skin infection caused by the virus of the same name. Even though it is common in children, adults with weak immune system and atopic dermatitis may also be affected by it. These benign and painless bumps disappear and usually don’t leave scars if left untreated. The duration of this infection varies as the bumps last from around two months to a couple of years.

Medical treatment is available for this infection, but isn’t necessary for the most part. The virus is difficult to treat in patients with weak immune systems and the lesions might be as big as fifteen millimetres.


The causes of contracting this virus are as follows:

1) By directly touching the infected area of the person.

2) Adults and teens may be infected during sexual intercourse.

3) Contact with substances that may be contaminated, such as towels, toys, and clothing items. The virus has the ability to survive on things that touch the surface of the skin.

4) Touching of bare skin during contact sports like football, basketball and wrestling may cause infection.

5) A person who already has this condition may experience a spread of it throughout the body as the virus can be transferred when the infected part of your body comes in contact with another during touching, shaving, or scratching.


The common symptoms of this condition are as follows:

1) The infected area develops firm, round, skin colored bumps on the upper layer of the skin.

2) Their size ranges from two to five millimetres.

3) The bumps usually have a dot or small umbilication at the top of it.

4) It may develop into an inflamed red colour and itch.

5) It commonly infects the neck, armpits, face, and arms in children and lower abdomen, thighs, and genitals in adults.
