At present, the incidence of cervical cancer and pre-cancerous lesions has increased, and the issue of HPV virus infection has aroused attention. Through this article, we hope to help young women not to panic once they are infected with the virus, but to face it correctly. 1, HPV virus infection is a very common phenomenon: HPV infection is very common in the general population. A woman who is sexually exposed, the probability of her getting HPV infection in her lifetime to be as high as 80%. And sexually active state women between the ages of 20-25 and 30-39 years old have the highest infection rate; 2, the vast majority of HPV virus infection is transient, most patients do not need to pass any treatment through their own immunity to clear the virus, in general, the clearance of low-risk HPV virus infection, high-risk virus clearance time in about 2 years; 3, the common types of HPV virus infection include: latent infection HPV infection: the virus can be detected, but did not cause lesions; subclinical infection: the virus can be detected, and through some special examination can find the manifestation of infection invisible to the naked eye, but no lesions that can be found by the naked eye; clinical infection: the appearance of lesions visible to the naked eye, or pathological examination found lesions. In addition, the principle of treatment for HPV infection is to treat the disease but not the virus, which means that HPV infection is found on physical examination but does not cause lesions clinically and does not require any treatment, and regular review is sufficient. The second feature is that most HPV infections are transient infections. This means that the infection will clear up naturally over a period of time without any treatment. Generally, the clearance rate can be as high as 90% or more within two years. The third characteristic is the potential carcinogenicity of high-risk HPV infections. After acquiring a persistent infection, high-risk HPV has the potential to cause lesions in the cervix and eventually lead to the development of cervical cancer. Evidence of the presence of high-risk HPV has been found in more than 99% of cervical cancer tissues, so HPV infection is a definite cause of cervical cancer.
