Infectious vaginal inflammation is the inflammation of the vagina caused by bacterial infections, which are broadly classified as follows: a. Candida infection, which often causes severe local itching of the vulva and a large amount of tofu-like discharge. Trichomonas infection, which also causes itching of the vulva, but the discharge is foamy, thin and large. Bacterial vaginosis, often caused by anaerobic bacteria, is characterized by a large amount of thin leucorrhea with a fishy odor. The above three are the most common bacterial infections that cause vaginal inflammation. It is recommended that routine laboratory tests of the leukorrhea be performed to determine which pathogenic bacteria are responsible for the infection, and then medication should be given accordingly.
