B34.4: Papovavirus infection, unspecified site

There are various kinds of viruses. You have been infected with a papillomavirus or polyomavirus.

Papillomaviruses cause cells in the skin and mucous membrane to multiply rapidly. These are then known as warts. Warts can occur singly or in groups. The warts often fade away again on their own. The warts can sometimes become very large or grow uncontrollably. They can then damage the surrounding tissue. Papillomaviruses are often transmitted through skin contact with the warts, less frequently through sex or at birth.

Polyomaviruses can cause various illnesses, for example in the brain, skin or kidneys. Papillomaviruses only cause illnesses when the defense system is very weak. In that case, you may be seriously ill. It is not known exactly how polyomaviruses spread. But many people are carriers of the viruses.
