According to the US CDC classification for HIV/AIDS based on CD4+ T-Lymphocyte Categories [29], the CD4+T cell counts ≤200 cells/μl (category 1), 201–499 cells/μl (category 2), and ≥500 cells/μl (category 3), accounted for 13.30% (n = 168), 58.42% (n = 739), and 28.46% (n = 360), respectively in our study. This evidence concerns the gene CD4 and AIDS.
