Women who have not had sex are called virgins, but they can still get gynecological diseases, the most common of which are vulvovaginitis and acute pelvic inflammatory disease. Bacterial vaginitis, mycobacterial vaginitis and trichomoniasis are the most common forms of vaginitis, as mycobacterial vaginitis is not caused by direct transmission from sex, but is directly related to blood glucose in the body, the use of broad-spectrum antibiotics, or anti-tuberculosis drugs. Women who wear chemical fiber panties that have not been dried may also be triggered to develop mycosis vaginalis. Trichomonas vaginitis is most commonly contracted through sexual intercourse, but can also be caused by indirect contact with public baths, tubs, and towels. The chances of acute pelvic inflammatory disease in virgins are relatively low, but for some immunocompromised women, in the case of inflammation in the vagina, it may also be upward leading to the emergence of pelvic inflammatory disease, the examination of ultrasound will find that there is a significant accumulation of fluid in the pelvic cavity, and there will be uterine corpus pressure and pain in the anal examination.
