摘要：

Based on the fact that HIV/AIDS manifests different transmissioncharacteristics and pathogenesis in different age groups, and the proportions ofyouth and elderly HIV infected cases in total are increasing in China, we clas sify the whole population into three age groups, youth (15-24), adult (25-49),and elderly (>=50), and establish a three-age-class HIV/AIDS epidemic modelto investigate the transmission dynamics of HIV/AIDS in China. We derivethe explicit expression for the basic reproduction number via the next gener ation matrix approach. Qualitative analysis of the model including the local,global behavior and permanence is carried out. In particular, numerical simu lations are presented to reinforce these analytical results and demonstrate HIVepidemiological discrepancy among different age groups. We also formulate an

optimal control problem and solve it using Pontryagins Maximum Principleand an efficient iterative numerical methods. Our numerical results of opti mal controls for the elderly group indicate that increasing the condom use anddecreasing the rate of the formerly HIV infected persons converted to AIDSpatients are important measures to control HIV/AIDS epidemic among elderlypopulation.
