Among individuals with CD4 count ≤ 350 cells/mm3 or missing CD4 count but diagnosed with AIDS, 198 deaths occurred, with mortality of 39.9% in the pre-intervention 2010 phase and 35.0% in the pre-intervention 2011 phase, compared to 13.0% in the post-intervention 2012 phase and 12.7% in the post-intervention 2013 phase (all p < 0.001). This evidence concerns the gene CD4 and AIDS.
