The Warts are caused by the virus of human papillomavirus (HPV).
This virus causes the rapid proliferation of skin cells, so benign lumps are developed that are more annoying than dangerous, but which is highly contagious.
The different types of the virus typically cause warts in different body areas.
The virus is transmitted by direct skin contact or by touching liquid surfaces.
After the first contact, the HPV virus can remain inactive or latent in the skin and may not be immediately visible symptoms.
This means that many people may be carriers of HPV without ever know it.
It may takes even six months to a wart to develop (incubation period).
Although we are all exposed to the HPV virus, some seem to be more sensitive to him, while others are naturally more resistant.
The warts occur most frequently when the immune system is weakened.
Children and adolescents are more likely to be affected, as they haven't developed (yet) antibodies against the virus and they have increased contact with people who have warts.
People who receive treatment with steroids or suffer from diseases that suppress the activity of immune system, such as infection by HIV, are also more likely to develop warts.
Most warts appear in the summer, because of the increased contact during activities, such as swimming and camping.
The two most common types of warts are the common wart and the plantar wart.
Common warts usually grow on fingers, the back of the palm hand, the arms and the legs. The plantar warts usually occur on the soles.
Common warts are benign lumps of skin. The common wart looks like a hard lump with rough surface which is like a cauliflower. The warts may be round or irregularly shaped, flat or raised, and can reach the size of a pea.
They may be white, gray or brown. Common warts usually grow around the nails, fingers and the back of the palm hand, but may also occur on the knees and face, especially in places where the skin is torn.
The warts are contagious and may spread to other parts of the body or spread to other people. For this reason, it is best to be treated immediately with treatment.
The warts are effectively treated depending on their size, using laser: the CO2 laser. The action of the laser is selective because of the detected thermolysis of lesions without destroying the surrounding normal tissues and additionally, because of the selective destruction of capillaries which feed the lesions.
Sessions become approximately every 20 days and the review every month.
On the monthly review should preclude the recurrence of new lesions which arise as subsidiaries of the first lesions because the incubation time of viral lesions is up to six months.
Criterion for healing is the complete lack of lesions for 6 consecutive months and the restoration of the epidermal dermatoglyphic lines.
Appearance of new lesions after the period of six months implies reinfection by HPV virus.
