Project Objective: The objective of the ARCAN project is to expand access to co mprehensive and evidence-based HIV/AIDS prevention, treatment, and care programs by supporting a network of subregional #learning sites# to expand training of h ealth care practitioners. The project will support HIV/AIDS-related health secto r human resource capacity building in Kenya, Ethiopia, and Tanzania using a #tra ining-of-trainers# (TOT) model. The project components include (a) health care p ractitioner training; (b) monitoring, evaluation and knowledge-sharing; and (c ) program coordination. It is expected that, as a result of increased capacity among health care practitioners in the subregion, this project will contribute t o the enhanced delivery of HIV/AIDS-related services, stronger linkages between prevention and care interventions, and expanded South-South partnerships.
