  • Digital Health Promotion and Community Involvements are key topics for SDG 3
  • Digital Health Promotion contributes to Digital Skills and is an enabler for the Digital Transformation
  • Accessible & Affordable Health Information: “Access to Health Information is a Human Right” and should be free of charge for every single human being

Questions and Discussions

Q: Are there examples of free access to health information?

Free Access to Health and Education

COVID-19 response by the Government of Ethiopia: Free access to health and education

Q: What about costs and access to the Internet, are these part of the projects for the users or not? What are your experiences?

  • The material costs for a WiFi InfoSpot are 450 USD, though we have additional costs (1100 USD) for configuration and installation and training on the ground (1000 USD). Thus in total, we have costs per village of about 2500 USD. If we can establish the competence within a country, we can lower the costs for configuration, and through free help and community initiatives we can bring down the costs of installation to “close to zero”.

Q:  The village platform: Can the system send information back – so you can also use this for early alerts for communicable diseases?

  • Yes, the village platform is connected to the Internet through a mobile network link, and thus can send information back. In principle, we could use machine learning to catch the early alerts, a topic for future research.

Q: In general: when implementing new technology there could be a main lack of trust in the new technologies. This has for example been seen when trying to implement digital contact tracing in different countries worldwide during this pandemic. How could one at best cope with this challenge when trying to implement new technology such as digital contact tracing or WiFi Information spot?

  • One of the proposed approached to increase the trust in new solutions is to involve the local community, as well as open and public information about the intervention.

Q: What is the state-of-the-art in making digital health available and accessible?

  • Apart from Ethiopia, who made access to health information “zero-rated” (free of charge) in the mobile network, we see developments in making educational and health content available free of charge. Examples are the Vodacom educational portal on education, offered free of charge in all mobile networks in Tanzania.
  • Furthermore, international organisations such as ITU, UNICEF, A4AI, IISOC, UNDP, USAid put their emphasis on last-mile connectivity. Though, having digital health as enabler for digital transformation is still a relatively new topic, and pushed a.o. by UiO through

Q: What is the type of population using the apps?

  • In the example of the Jichunge App, the study was performed in urban areas in Dar es Salaam and Tanga (TZ). As the focus of the study was on personal app usage, we selected urban areas where the ownership of a Smartphone and access to the Internet is easier.

Q: What are your experiences with knowledge retention?
