Addressing national health challenges requires the mobilization of resources from both the public and private health sectors. More than one-third of general health services available in Tanzania are accessed at private health facilities. However, the full potential of the private sector — health facilities, private drug outlets and pharmacies, commodity supply companies, commercial banks, and micro-financing institutions — has not yet been fully exploited. The Frontier Health Markets project aims to improve market environment for greater private sector participation in the delivery of health products and services and improve equal access to, and uptake of, high-quality consumer-driven health products, services, and information by customers and patients.
