Comparison of different strategies for controlling HIV/AIDS spreading in MSM

As proposed in the UNAIDSs 2014 report, to end global AIDS epidemic by 2030, 90% of people living with HIV need to be diagnosed, 90% of the diagnosed need to receive antiretroviral therapy (ART), and 90% of those on treatment need to achieve viral suppression (90-90-90 strategy). The strategies focus on the reservoir. It controls HIV spreading by reducing infectiousness of HIV infected individuals via diagnosis and treatment. In this manuscript, we compared the effects of HIV/AIDS interventions that focus on different individuals in MSM population through a dynamics model. Our results showed that, the success or not of the ”90-90-90” strategies depends on a very important factor: the infectious strength among individuals taking ART. Without highly effective HIV treatment, the ”90-90-90” strategies are likely to fail. Therefore, we call for the combination of both primary prevention among the susceptible with the 90-90-90 strategy among the infected to curb the HIV epidemic in Chinese MSM.
