Human Papillomavirus HPV

Human papillomavirus (HPV) is one of the most common causes of sexually transmitted disease (STD) in the world. Experts estimate that as many as 24 million Americans are infected with HPV, and the frequency of infection and disease appears to be increasing. More than 60 types of HPV have been identified by scientists. Some types of the virus cause common skin warts. About one-third of the HPV types are spread through sexual contact and live only in genital tissue. Low-risk types of HPV cause genital warts, the most recognizable sign of genital HPV infection. Other high-risk types of HPV cause cervical cancer and other genital cancers.

Like many sexually transmitted organisms, HPV usually causes a silent infection, that is one that does not have visible symptoms.

One study sponsored by the National Institute of Allergy and Infectious Diseases (NIAID) reported that almost half of the women infected with HPV had no obvious symptoms. Because the viral infection persists, individuals may not be aware of their infection or the potential risk of transmission to others and of developing complications.
