What is Molluscum contagiosum?

Also known as MCV, it is a contagious infection caused by the molluscum contagiosum virus. It is generally a harmless infection from the family of poxviruses.

How is MCV transmitted?

MCV is transmitted via direct skin-to-skin contact, which can include sexual contact, or sharing towels, flannels, bedding, or other contaminated materials. 

If you have MCV, you can still do normal activities such as swimming, sports, going to school, or work. 

You are contagious until the last spot has disappeared, a however once you have had it once, you develop an immunity to MCV and cannot get it again. 

Symptoms

The only symptom is spots on the skin which are about 2-5mm wide and appear in clusters. They are dome-shaped, raised with a shiny-white dimple in the middle. Most people get an average of 30 or less across the body. 

If you get it from sexual contact, the spots appear on the lower abdomen (stomach), genitals, and thighs. Children or people with a weakened immune system can get the spots on the folds of the skin, (groin, armpits, and behind the knees), face, chest, back, or around the eyes. 

Prevention and protection

To reduce the chances of spreading MCV you should: 

  • Avoid sharing towels, bedding, flannels or clothes  

  • Use a condom when having sex (this may not completely stop the skin-to-skin transmission but reduces the chances) 

  • Avoid direct skin-to-skin contact with people

Treatment

Treatment is not usually required because it clears up on its own. If the spots are causing issues such as secondary infections, or if you have a weakened immune system. Treatment usually includes antibiotic creams, or cryotherapy (freezing). 

Where to get help in Bexley

It is recommended that you see your GP if: 

  • The spots are near your eyes

A doctor or nurse will look at the lesions and make a visual diagnosis. It is not common to have other tests such as urine or blood samples taken.
