HPV stands for Human Papilloma Virus. They are a group of non-enveloped DNA viruses that specifically infect human epithelial cells.
There are about 100 types of HPV that affect different parts of the body.
The majority of these sub-types cause no symptoms and do not cause cervical cancer. They are categorized to be of the LOW-RISK strains. Low-risk HPV subtypes include types 6 and 11 that cause 90 percent of genital warts.
HIGH-RISK HPV strains, on the other hand, are more often associated with precancerous tissue changes of the cervix that may lead to cervical cancer, if left untreated over many years. More than 70 percent of cervical cancer cases can be attributed to two types of the virus, HPV-16, and HPV-18.
