Mycoplasma is a normal flora of the human body and can be found in the vagina of normal healthy women, with a residency rate of 50-80% in the lower genital tract of pregnant women. If there are no symptoms, only mycoplasma found by laboratory indicators, it can be left untreated. However, when resistance decreases, symptoms of infection can appear, and when symptoms appear, treatment is required. Mycoplasma infection is a curable vaginitis and treatment of mycoplasma positive (mycoplasma infection) requires only oral broad-spectrum antibiotics, which can be selected based on drug sensitivity tests. Commonly used drugs: Azithromycin 1 gram is preferred as a dose; or Erythromycin 0.5 gram twice daily for 14 days. It can be rechecked (mycoplasma culture + drug sensitivity) in 1-4 weeks after stopping the medication.
