Digital health is taking its first steps in some African, Asian and Latin American countries. The number of initiatives is growing, with a widespread opinion that digital health can help address key healthcare issues if it reaches scale. This report by GSMA Intelligence provides an overview of the healthcare landscape in developing countries and assesses the role of digital health to help address key issues. It looks at technology enablers, challenges, use cases and evidence of the positive impact digital health can have on key health indicators. The report also assesses the role and opportunity for mobile operators and what needs to be done to scale digital health.
