Molluscum contagiosum

This is a very common skin infection caused by a virus (poxvirus) and which occurs much more often in children than in adults. Transmission requires direct contact with hosts or contaminated fomites. The incubation period ranges from 2 to 8 weeks. It usually presents as a dome-shaped ‘spot’ with a dip in the middle of between 1 and 5 mm in diameter. It can appear on any area of ​​the skin’s surface. Although it is a self-limiting disease, it generally requires treatment because of the family’s concern, to prevent an increase in the number of lesions through autoinoculation, and to prevent the possibility of contagion. Various treatments are available, and the most appropriate one will be chosen on the basis of the patient’s medical history, the extent of the lesions and any previous treatments undertaken.
