What are Human Papillomavirus (HPVs)?
Human papillomaviruses (HPVs) are a group of more than 100 types of viruses. They are called papillomaviruses because certain types may cause warts or papillomas, which are benign (non-cancerous) growths. The HPVs that cause the common warts which grow on hands and feet are different from those that infect genitals and other areas.
