ABSTRACT
This chapter considers key populations in HIV/AIDS epidemics. The chapter gives a brief overview of the various pathways for the spread of the virus throughout key populations and among the general population. A population is considered key in HIV/AIDS epidemics due to generally high infection rates and the role that they can play in spreading HIV. They are also considered key populations due to the vulnerability they face whether through systematic violence, risk behaviours or mobility. These key populations include CSWs, PWID, HIV+ pregnant women, FPD and MSM. Moreover, the impact of PRC laws regarding the criminalisation or illegality of FSWs, IDUs, and undocumented workers will be considered in light of the spread of HIV/AIDS in Yunnan and nearby areas.
