  1. The infection, immunosuppression, and treatment rates were estimated using the MHIPS data whereas the mortality rates stemmed from reference [14]. Compartment S: HIV-negative individuals; compartment I1: untreated HIV-positive individuals with CD4 cell count >350 cells/mm3; compartment I2: untreated HIV-positive individuals with CD4 cell count ≤350 cells/mm3; compartment T: HIV-positive individuals on ART
