Pneumonia in HIV patients is not necessarily advanced, it depends on what kind of pneumonia is present and whether it is caused by a rare pathogen. The patient’s immune function, such as the CD4+ T-lymphocyte count, also needs to be assessed. If the CD4+ T-lymphocyte count is close to normal, the patient is not at an advanced stage. If the CD4+ T-lymphocyte count drops significantly to less than 200mm^3, then the patient is in the advanced stage of AIDS. At this time, anti-infective treatment should be carried out in a timely manner, and appropriate antiviral drugs should be selected according to the specific situation, so that the patient’s immune function can be restored and the CD4+ T-lymphocyte count will gradually increase by suppressing the replication of the AIDS virus.
