On this 8th episode of the RIA podcast we are discussing COVID-19 contact tracing with Dr. David Johnson from the Department of Computer Science at the University of Cape Town. David has recently conducted research on contact tracing which he will be discussing, as well as South Africa’s new contact tracing app, COVID Alert.
In it we talk about contact tracing at both technological and non-technological levels. First we will discuss what contact tracing is, then we will discuss technological approaches to contact tracing. We will then discuss both the technological limits of, and access barriers to contact tracing. We will also discuss South Africa’s previous mobile-location based contact tracing approach, and the WhatsApp and USSD based COVID information app.
Finally we discuss the Google Apple Exposure Notification (GAEN) protocol, as well as the new GAEN-based South African App, COVID Alert.
