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.)
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.
