Molluscum

What is molluscum?

Molluscum contagiosum is a skin infection caused by a virus.

How do you get molluscum?

You can get molluscum:

• by having skin to skin (including sexual) contact, with someone who has molluscum
• from touching a surface that has the virus on it, such as a towel, gym equipment or tanning bed
• by scratching or shaving an already infected area, which could spread molluscum from one part of the body to another

How can you tell if you have molluscum?

Symptoms may appear from one week to six months after contact with the virus
You might notice:

• small white, pink, or flesh coloured raised bumps with a dimple or pit in the centre. The bumps are usually smooth, firm and painless. They may become red, sore, itchy, or tender.
• bumps that appear anywhere on the body, alone or in groups. They are most commonly found on the abdomen, groin, buttocks, thighs, and external genitals.
• individual lesions that usually disappear within 2-3 months without treatment, but the infection may persist up to two years with periodic outbreaks

People with a weakened immune system (for example those with HIV or cancer) may experience more severe symptoms

How do you get tested for molluscum?

A health care provider can tell if you have molluscum by looking at your bumps

How is molluscum treated?

Molluscum can be treated with liquid nitrogen (freezing) or a cream that you can apply. A dermatologist may use other treatment methods. Treatment of bumps can reduce the spread to sexual partners.

Do you need follow-up?

You will need follow-up if you continue to have symptoms after your treatment is finished. It may take more than one treatment to get rid of the molluscum.

How do you protect yourself and others?

• Do not share towels or personal items
• Use a condom or other barrier every time you have sex
• Abstain from sex while molluscum is present
• Avoid touching, picking, or scratching the bumps as this can cause a bacterial skin infection in addition to the molluscum
• Wash your hands frequently especially after touching the bumps
• Do not shave the area as it may cause the bumps to spread
• Get an STI check up if you or your partner notice bumps
• Consider getting immunized for hepatitis B and HPV
