Clinically, there are several possible causes of vaginal fever in women: first, reproductive tract infection is the most common cause of vaginal fever in women, when women suffer from vaginitis, pelvic inflammatory disease, endometritis, tubal inflammation, especially when women suffer from vaginitis and endometritis, these two inflammatory diseases can directly cause vaginal fever in women, when there is vaginitis the permeability of vaginal mucosa capillaries increases, there is exudation of inflammatory material When there is vaginitis there is an increase in the permeability of the vaginal capillaries, there is an exudation of inflammatory material and there is also an exudation of inflammatory cells and inflammatory secretions from the blood vessels onto the mucous membrane of the vaginal wall. The exudate contains pyrogen, which can act on the local skin mucosa of the vagina to produce vaginal fever. As the body struggles with bacteria or viruses during inflammation, the local blood circulation is temporarily accelerated and the local oxidative decomposition is accelerated, which can also lead to increased heat production and vaginal fever. Secondly, women with multiple sexual partners should be suspected of having STDs, such as gonorrhea, AIDS, syphilis, etc. Viruses can also produce thermogenic substances that cause vaginal fever.
