HPV56 is a human papillomavirus infection, which can be found everywhere, i.e. on the skin, mucous membranes and in the surrounding environment. If a woman carries the virus around her perineum or male genitalia, she can bring the virus to the vagina and cervix through sexual intercourse, and the virus can grow and multiply in the mucous membrane of the vagina and cervix. If the infection persists for more than two years, it may cause precancerous lesions of the cervix. If the virus is not treated in time, it may develop into cervical cancer after 3-5 years, but the chance of this is very low.
