ACA is an alliance of 37 member institutions in 12 African countries established in 1997 to provide sustainable capacity solutions in Africa. It implemented a project in collaboration with AMREF to strengthen the capacity of community health workers in Migori County, Kenya to diagnose and manage HIV/AIDS. A mobile phone application was developed and installed on the phones of 32 health workers to provide remote access to expertise. Evaluation found the application reduced remote consultations and increased health worker knowledge. While useful, connectivity and device issues need addressing to optimize the mobile learning approach.
