Objectives: Improve models for estimating HIV epidemic trends in sub-Saharan Africa (SSA). Design: Mathematical epidemic model fit to national HIV survey and ANC sentinel surveillance (ANC-SS) data. Methods: We modified EPP to incorporate age and sex stratification (EPP-ASM) to more accurately capture the shifting demographics of maturing HIV epidemics. Secondly, we developed a new functional form for the HIV transmission rate, termed...
