We can state that this document was created from existing experiences in European CBVCT centers and from international recommendations. The current document is partially based on the HIV- COBATEST deliverables, which is a limited source of information. Besides, there are some methodological limits (for more details, seethe deliverables on www.cobatest.org ). Most of the experiences described in this guide come from CBVCT targeting men who have sex with men (MSM). This is not surprising, since the MSM community has been very active in the fight against AIDS since the beginning of the epidemic. Nevertheless, other communities might express other needs or might prefer other ways of performing CBVCT. This guide is not a final but a dynamic document, since input from future experiences should be a key element for its evolution. Justin the same way that the HIV epidemic, national contexts, and HIV screening regulations also evolve and develop.
