In 2013, The WHO together with UNFPA, UNAIDS, UNDP the Global Network of Sex Work Projects (NSWP) and the World Bank published ‘Implementing Comprehensive HIV/STI Programmes with Sex Workers: Practical Approaches from Collaborative Interventions’ (or the SWIT as the document has become known). The SWIT reaffirms that the health of sex workers doesn’t happen in a vacuum, and that countries should work towards the decriminalisation of sex work, and the empowerment and self-determination of sex working communities, as a fundamental part of the fight against HIV.
