This second volume of the mHealth compendium, produced by the African Strategies for Health Project for USAID in June 2013, contains twenty-seven case studies which document a range of mHealth applications being implemented mainly throughout Africa, but also in other regions. In order to help USAID missions access relevant mHealth information, this compendium offers project descriptions, publication references and contact information for making further inquiries. Each two-page case study includes an introduction to the health area or problem; a description of the mHealth intervention highlighted; a description of any important results or evaluation findings; lessons learned; and conclusion. In addition, the second page includes a summary of the geographic coverage, implementation partners, and donors, as well as contact information for the implementing partner and donor. The case studies in this compendium have been organized within five programmatic areas: 1) Behavior Change Communication; 2) Data Collection; 3) Finance; 4) Logistics; and 5) Service Delivery.
