A sex work guidance document has just been published by UNAIDS. It is a big improvement over the last one. You can download it from below or from http://data.unaids.org/pub/BaseDocument/2009/jc1696_unaidsguidancenote_hiv_and_sexwork_en.pdf. The [him] moderator will also email you a copy. It is a 300 kb PDF file.
