The transmission of ureaplasma urealyticum in women includes sexual contact and indirect contact. 1. Sexual contact: Ureaplasma urealyticum is mainly transmitted sexually, because Ureaplasma urealyticum is usually parasitized on the mucous membrane of the genital tract and the epithelial cells of the urethra of the infected person, and if a woman’s sexual partner carries Ureaplasma urealyticum, the chances of being infected will be increased when the woman’s resistance decreases. 2. Indirect contact infection: Because the ureaplasma urealyticum may be stored in underwear, towels and other items. If a woman comes into contact with a toilet seat, towel, or underwear that has been infected by a Ureaplasma urealyticum-positive patient, indirect contact transmission of Ureaplasma urealyticum may result. If a sexual partner has Ureaplasma urealyticum infection, he or she should seek prompt medical treatment. During the treatment period, it is necessary to pay attention to good protection to avoid cross-infection.
