It is a skin growth on the soles of the feet caused by a viral infection. Contagion can occur by direct contact or by contact with the blood of the infected person, which is favoured by the weakened immune system of the infected person. They are often spread in public baths and swimming pools, by sharing shoes, etc. They may or may not be painful, depending on their size, duration, location and type of virus. They are diagnosed by a medical history and physical examination. If they cause discomfort or multiply, it is advisable to see a dermatologist to have them removed.
