What are human papilloma viruses (hpv)?

DNA viruses: Hpvs are dna viruses that can cause warts, premalignancy / dysplasia, and cancers in people. Some strains are associated with skin infections and cause warts only (like warts on feet and fingers). Other strains are more commonly seen on the genitals (cervix, vagina, penis, anus, etc...) and can be spread by sexual contact. The pap test and hpv dna tests and biopsies are used to diagnose hpv.
