"STIR UP" is a Strategic Information Planning and Response Setting Workshop that was held after compiling the local HIV Estimates and Surveillance work. It has, for the first time, brought together site coordinators, City Health Officers and NGOs with the task of working together to help craft key messages of slowing down the spread of HIV. Spearheaded by the Philippine National AIDS Council, the National Epidemiology Center, with support from UNAIDS, this workshop was held last 18-20 November 2009 at One Tagaytay Place, Tagaytay City.
