There are more than 100 subtypes of HPV, and the most common skin infections such as common warts and flat warts are caused by HPV infection. About 30 HPV subtypes can be transmitted through the genital tract. There are two types of HPV according to their harmfulness, such as low-risk types that cause benign lesions and high-risk types that cause malignant lesions, which are carcinogenic. HPV types 6 and 11 are the most common low-risk HPV types that cause condyloma in the anus and genital tract, and simple low-risk HPV infections do not turn into cancer. The 13 most common high-risk HPV types are 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68. Of these, types 16 and 18 are the most common. The occurrence and development of cervical cancer is a long process from quantitative to qualitative changes and from gradual to sudden changes. In the past, it was thought that it took 10 to 20 years for cervical squamous intraepithelial neoplasia to develop into cervical invasive cancer, but now this process is gradually shortening. The age of cervical cancer patients tends to become younger. Among the sexually active population, about 20% to 80% or more have a history of HPV infection. Although condyloma acuminatum as a common STD is mostly a low-risk HPV infection, our many different studies have found that many patients can combine multiple subtypes of HPV infection, i.e. multiple HPV infections, and even combined high-risk HPV infections are not uncommon. The actual fact that many patients have warts that are not easily cured or recur frequently is also related to the combination of high-risk HPV infections. Therefore, it is very necessary for patients with warts to undergo HPV typing and cervical cytology examinations in order to keep abreast of HPV infections and to regularly monitor and prevent or treat high-risk HPV infections in a timely manner.
