Candida vaginitis is a disease that tends to recur, so it is important that you understand its causes and modes of transmission before you can target it. Etiology Candida albicans is a fungus. Candida is not very resistant to heat and can die when heated to 60°C for 1 hour; however, it is more resistant to dryness, sunlight, ultraviolet light and chemical agents. Candida albicans is a conditional pathogen, when the vaginal glycogen increases, acidity increases, and local cellular immunity decreases, it is suitable for the reproduction of Candida to cause inflammation, so it is mostly seen in pregnant women, diabetic patients and those who receive a lot of estrogen treatment. In addition, long-term application of antibiotics. In addition, the long-term application of antibiotic disorder changes the interrelationship between microorganisms in the vagina; corticosteroids or immunodeficiency syndrome. Wearing tight-fitting chemical fiber underwear and obesity can increase the local temperature and humidity of the perineum, which also makes Candida easy to reproduce and cause infection. In addition to parasitizing the vagina, Candida can also parasitize the oral cavity and intestinal tract, and the Candida in these three parts can infect each other, making it easy to develop when the local environmental conditions are suitable. In addition. A small number of patients can be infected directly through sexual intercourse or indirectly through contact with infected clothing. Treatment of recurrent cases Candida vaginitis is likely to recur before menstruation after treatment. Therefore, after treatment, the leucorrhoea should be rechecked before menstruation. About 5-10% of recurrences of Candida vaginitis occur after treatment. The causes of recurrence should be examined, such as the presence of diabetes, the use of antibiotics, estrogen or steroids, the wearing of tight-fitting chemical underwear, and the stimulation of local medication, to eliminate triggers. Sexual partners should be examined and treated for Candida, and condoms should be used for relative isolation during intercourse. Since intestinal Candida and deep vaginal Candida are important sources of repeated infections, antifungal agents should be administered systemically and the dose and application time of antifungal agents should be increased.
