The Smart Sex Worker’s Guide to SWIT provides a short summary of the key points in Sex Worker Implemetation Tool (SWIT). The Sex Worker Implementation Tool (SWIT) offers practical guidance on effective HIV and STI programming for sex workers. It provides evidence for the necessity of decriminalisation of sex work, the involvement of sex workers in developing policy, and the empowerment and self-determination of sex work communities as a fundamental part of the fight against HIV. This resource is based on the WHO, UNFPA, UNAIDS and NSWP 2012 recommendations on HIV and Sex Work. The guide can be used by sex workers and sex worker organisations who are designing or running programmes for sex workers. It may also be useful as an advocacy tool when advocating for rights-based services.
