Pus-like leukorrhea is often indicative of an anaerobic infection, such as bacterial vaginitis, but since there can be mixed infections, such as bacterial vaginitis combined with mycoplasma or mycobacterial infections, it is not possible to determine the type of infection simply from the nature of the leukorrhea. Therefore, when the leukorrhea is purulent, it is recommended to have a routine examination of the leukorrhea and, if necessary, mycoplasma and gonococcus to determine the specific type of infection. If the type of infection is determined and a drug sensitivity test can be done, a sensitive antibiotic can be selected. If a sensitivity test cannot be done, the appropriate antibiotic treatment can be chosen. At the same time, the patient will also need a gynecological internal examination to see if the infection is in the vagina, cervix or uterine cavity. After determining the site of infection, treatment can be chosen, for example, local medication for vaginal and cervical inflammation, and oral or intravenous infusion for pelvic inflammation.
