 The response of the government of China to the HIV/AIDS crisis evolved in tandem with the epidemic itself.Generally, policy moved from preventive and containment measures aimed at keeping the disease from reaching the general population, often with a reliance on enforcement of public morality, to more active, data-driven control measures involving targeted education and harm reduction programs.Early law and policy implementation were often hindered by lack of knowledge among lawmakers on the severity and impact of HIV/AIDS and its potential for growth within China.
