This is a viral infection that affects the skin. It most commonly affects children.

What are the symptoms?

The main symptom is small spots on the skin. These are usually firm and dome-shaped, with a small dimple in the middle. They are typically pink or red, and may have a tiny white or yellow head in the centre. If broken, the spot will release a thick yellowy-white substance, which is highly infectious. It is best to refer someone presenting with these symptoms to the pharmacist.

What are the treatment options?

Most cases will clear up without treatment in around six to 18 months. Treatment is usually only recommended for older children and adults when the spots are particularly unsightly and affect quality of life.

A topical treatment containing potassium hydroxide (example: Molludab), can be suggested. This works by breaking down the skin cells infected by the virus, allowing the immune system to fight it.

The following advice should also be passed on to customers:

• Avoid squeezing or scratching the spots, as this can increase the risk of the infection spreading, cause pain, bleeding and scarring
• Keep affected areas of skin covered with clothing, whenever possible
• Avoid sharing towels, flannels and clothing
• Avoid sharing baths.
