| Figure 1: Flow diagram of the model. Simulated population is stratified in compartments by gender as men (subscript g = m) or women (subscript g = w) and by HIV status as susceptibles (S), infected with wild HIV (I), infected with drug-resistant HIV through transmission (IR), individuals who developed (acquired ) resistance on PrEP (Ir) and AIDS (A). PrEP users may strictly follow the prescribed daily regimen (perfect adherers, superscript p) or decide to share their pills (primary sharers, superscript p1) with untracked users (secondary sharers, superscript p2). A complete description of the model is presented in the Technical Appendix. |
