Human papilloma viruses are a particular type of viruses, which affect the skin, as well as the mucous membranes, especially the genital ones. There are around one hundred and fifty such viruses, and the most common transmission way is through sexual contact. The vulgar manifestations of this virus are commonly known as moles or even worse, warts.

Different types of viruses from this class have the tendency to appear on certain areas of the skin. It is very important to know that there are some of these viruses, which can lead to cancer; those are the viruses with high level of risk. They can cause carcinomas in both men and women in the genital area.

There are also some types, which are viral viruses, and they are found in the lesions caused by them. These lesions can transform, under the influence of solar rays, into carcinomas, meaning an aggressive type of skin cancer. The evolution is very slow and it can stay out of sight for a long period. The vulgar manifestations of the virus, the moles, and the warts present themselves like growths of the skin. Sometimes, through their transparence, small thrombosis blood vessels.

The location of these growths is mainly on the fingers and on the hands. When they are found on the palms or on the foot, they can become painful and they can cut the natural lines of the skin. Flat moles are different from the vulgar ones by the shape they have. The surface of these moles is smooth and their dimensions are much smaller, they only measure a few millimeters. They are frequent on the skin of children and they localize mostly on the face, hands, and legs.

Hair-shaped moles are fine growths, which have the same color as the skin and they are usually located especially at the neck level. Contamination occurs after direct contact with contaminated individuals. Sexual contact is what causes them to spread. The transfer of the virus happens while having direct contact with traumatized areas of the skin.

The growths can appear more often on the skin of the people using public pools, or on the skin of the people working in a certain field, like for example butchers. So, the sexual contact is not the only transmission mean of these viruses.

Because of the fact that the majority of them are sexually transmittable, an individual with many sexual partners could be a major risk. It can also be transmitted from the mother to the newborn, if the mother has genital moles, in which case the baby has respiratory affections, probably by breathing in the virus during the birth process.

The sexual transmittable form of the virus is the most common sexual transmittable disease. The incubation period, meaning the time from exposure - contact - to the appearance of the lesions varies between two and nine months. All this time, the infected individual can transmit the virus to other people as well. So, the one thing we should all keep in mind when starting a sexual relationship with a new partner is to protect ourselves as well as we can.
