The most common cause of infection for a positive Ureaplasma urealyticum is caused by unclean sexual intercourse, which may also be due to sharing unclean towels or tub baths, and these channels of infection are also possible. It is recommended that if there is a polyurea ureaplasma infection, it must be actively treated. The treatment plan recommends the use of erythromycin, doxycycline, minocycline, azithromycin, etc. These drugs are treated continuously for 7-10 days and can generally achieve clinical cure. It is recommended that having a spouse or having sexual contact should be examined and treated at the same time to prevent repeated cross-infection between husband and wife, resulting in long-term failure to cure.
