The Sex Worker Implementation Tool (SWIT) offers practical guidance on effective HIV and STI programming for sex workers. The Asia Pacific Network of Sex Workers has worked for decades to ensure the rights of sex workers of all genders and to combat the HIV epidemic. SWIT is based on the evidence that community empowerment and community leadership has the potential to stop HIV/Aids epidemic through meaningful involvement and specific actions, specifically applied to sex workers. This documentation of APNSW member organizations SWIT experience demonstrates that community empowerment, sex worker leadership, and a united and informed sex worker community, and meaningful involvement of sex workers has the potential to stop the HIV/Aids epidemic. However, this documentation also demonstrates the need to influence not only sex workers but governments, NGOs and law enforcement in order to create an enabling environment for sex workers to be part of the solution to the HIV pandemic.
