The HIV epidemic continues apace among gay and bisexual men in England, with about 1,300 men becoming infected each year.This third edition of Making It Count serves the same purpose as its predecessor: it is both a planning framework for collaboration in HIV prevention and a framework for local and national action. It has been developed in collaboration with a wide range of stakeholders (see Acknowledgements). It describes where we are now, the directions we want to be moving in and what needs to change to get there. Understanding these staging posts requires understanding of the social context of the epidemic. Making It Count therefore also presents a succinct social commentary on the HIV epidemic among gay and bisexual men. The chapters outline a wide number of actions that can be taken by a wide range of key players at both national and local level.The challenge to the authors has been to describe these actions with sufficient specificity for people to act on them but with enough generality that they are not almost immediately out of date. In most cases we have described the direction of change rather than a (utopian) endpoint.
