  The Covid-19 outbreak threatens to saturate healthcare systems in most
Western countries. We describe how digital technologies may be used to
automatically and remotely monitor patients at home. Patients answer simple
self-reported questionnaires and their data is transmitted, in real time, to a
Command Centre in the nearest reference hospital. Patient reported data are
automatically filtered by algorithms to identify those with early warning
signs. Open-source code of all software components required to deploy the
remote digital monitoring platform and Command Centres is available.
