There are more ways of transmission of mycobacteria, most women are not infected through sexual contact, it is mainly endogenous transmission. In addition to the vagina, mycobacteria can also be found in the mouth and intestinal tract, and these three parts of the mycobacteria can infect each other and cause infection once the conditions are right. Only a very small percentage of patients can be infected through sexual intercourse, and a small percentage can be infected indirectly through contact with infected clothing. Women with mycosis vaginalis need to be treated actively on the one hand and to find the causes of the mycobacteria on the other hand, because the decrease in body resistance and the increase in vaginal acidity can lead to the onset of mycosis vaginalis.
