The human papillomavirus (HPV) belongs to a group of viruses that infect the skin and mucous membranes.
Symptoms. It can produce mostly benign lesions, such as warts on the skin and genital warts and, more rarely, malignant lesions such as some types of cancer (cancer of cervix, penis, vulva or anus).
Prevention. There are over a hundred types of HPV that can infect different parts of the human body: Some infect the skin of the hands, face or the soles of the feet, while others infect the skin or mucous membranes of the anogenital region and the oral cavity. Of these, nearly a dozen types may promote the development of cancer. A person can become infected with more than one of the different types of HPV.
