Towards the vision of zero new HIV infections, zero discrimination, and zero AIDS-related deaths, the UNAIDS 2011-2015 Strategy expressly calls for accelerated efforts in countries where the leveraging of the UN system and other capacities will have the greatest impact.  The Joint Programme, together with governments, civil society and other partners, will help countries identify such areas in which to fast-track the delivery of HIV-related services. A differentiated approach, country by country, city by city and district by district,  will ensure that people in need are not left behind.
