AIDS progression can be divided into acute AIDS infection, asymptomatic stage, AIDS stage, if it has entered the AIDS stage, and no treatment, the survival time will be greatly shortened, only 12 to 18 months, but if detected in time, and active treatment, the survival period can reach decades or even longer. So at this point the patient needs to be clear about the specific stage of HIV infection they are in and actively seek formal treatment.
