hpv-Human papilloma virusHuman papilloma virus (HPV) is a set of sexually transmitted diseases (STD), which take into their purview cervical cancer and genital warts, caused by human papilloma viruses.

Genital warts (or condyloma, condylomata, acuminata, or venereal warts) is a highly contagious sexually transmitted infection which is caused by some sub-types of the human papilloma viruses (HPV). It is often seen that genital warts are spread through direct skin-to-skin contact during oral, genital, or anal sex with an infected partner. Among the most easily recognized sign of genital HPV infection are genital warts. From among the multiple strains of genital HPV, strains 6, 11, 30, 42, 43, 44, 45, 51, 52, and 54 can cause genital warts and types 6 and 11 are the most common.

Most people who acquire those strains never develop warts or any other symptoms. HPV is also responsible for over 90 per cent of all cases of cervical cancer. (However, the HPV strains responsible for cervical cancer differ from strains that cause genital warts.)

Genital warts are often likely to be found in clusters that are tiny or could spread into large masses in the genital or anal area. In women, the warts occur on the outside and inside of the vagina, on the opening (cervix) to the womb (uterus), or around the anus. Though genital warts are almost as common in men, the symptoms of the disease are less obvious. The symptoms of HPV in men are usually seen on the tip of the penis. They may be found on the shaft of the penis, on the scrotum, or around the anus. Rarely, genital warts also can develop in the mouth or throat of a person who has had oral sex with an infected person.
Out of the 120 known HPV types, 37 are transmitted through unsafe sexual contact. It is rather common in adult populations all over the world to be infected through sexually transmitted HPV. Some HPV, such as types 6 and 11, are known to be the cause of genital warts. But it is also seen that many genital HPV infections affect a person without any symptoms and the infected person doesn’t even come to know about it. On the other hand, some HPV infections linger and these comprise a subset of about 19 ‘high-risk’ HPV types that can lead to development of cervical cancer or other genital/anal cancers.

The two most common high-risks of HPV, types are 16 and 18. Together, these two HPV types cause about 70 per cent of all cervical cancer. HPV types 6 and 11 together cause about 90 per cent of all cases of genital warts.
The development of cervical cancer has not been studied in detail or for a long time yet, so it is commonly believed that the prevention of the cervical precancerous lesions (or dysplasias) is likely to result thereby.

According to a 2006 study, vaccines may offer limited protection against a few HPV types closely related to HPV 16 and 18, but it is clear that other high-risk HPV types can circumvent the vaccines.
