This report defines eHealth and its applications for developing countries and highlights case studies on eHealth services and systems from more than 40 countries, as well as eHealth ecosystem and standards – both technical and for service quality. Special attention is dedicated to mobile applications as ~7 billion people, or 95 per cent of the global population live in areas covered by mobile-cellular networks. The results and guidelines presented apply to all – national and local administrations, individual practitioners, group practices, healthcare systems, as well as to providers of health-related services where there are eHealth interactions either directly to the patient or from provider to provider for the purposes of healthcare delivery.
