Projecting the Dynamic Trends of Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome: Modeling the Epidemic in Sichuan Province, China.

Objective: Our study aimed to provide a comprehensive overview of the current status and dynamic trends of the human immunodeficiency virus (HIV) prevalence in Sichuan, the second most heavily affected province in China, and to explore future interventions.

Methods: The epidemiological, behavioral, and population census data from multiple sources were analyzed to extract inputs for an acquired immunodeficiency syndrome (AIDS) epidemic model (AEM). Baseline curves, derived from historical trends in HIV prevalence, were used, and the AEM was employed to examine future intervention scenarios.
