Ureaplasma urealyticum positivity is not AIDS, and Ureaplasma urealyticum positivity is not even diagnostic of a sexually transmitted disease. In the past, Ureaplasma urealyticum was regarded as a kind of sexually transmitted disease (STD), which could cause nongonococcal urethritis or nongonococcal cervicitis. Later, it was found that normal people carry Ureaplasma urealyticum in their bodies, and now it can be considered as a normal parasite. Some Ureaplasma urealyticum infections do not need treatment if there are no symptoms, especially for couples who already have children, if they have Ureaplasma urealyticum infections and there are no symptoms, they can choose not to be cured, but need to be treated when one of the parties has symptoms. The biggest danger of Ureaplasma urealyticum may affect pregnancy or fertility, so couples of childbearing age who have not been pregnant for a long time and have Ureaplasma urealyticum infection can be treated. Ureaplasma urealyticum is a type of mycoplasma, which is divided into Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium. In these three categories, Ureaplasma urealyticum has a weaker pathogenicity and often carries pathogens, while Mycoplasma genitalium is the one that really causes disease. So if you have Ureaplasma urealyticum infection, you can check Mycoplasma genitalium, and if Mycoplasma genitalium is also positive, you need to treat it. But it has nothing to do with AIDS, and the incidence of Ureaplasma urealyticum is not necessarily higher in AIDS patients, and its pathogenicity is not stronger. In conclusion, there is no relationship between Ureaplasma urealyticum infection and AIDS.
