This article elaborates a typology of organisational responses during the first decade of AIDS/HIV in a dozen Western European countries. We~Care mixes: that is, the division of task between all producers of welfare (both private and public), and the processes at work in these policies, are analysed. Three types are identified, presenting unexpected variants in respect to general typologies of Western welfare states. They underline the importance of non-profit actors and also argue that new forms of co-operation between those actors and public ones can lead to renewed management of the main social issues currently facing Western welfare states.
