One solution could be a new open-source app that permits contact tracing for potential coronavirus infections while preserving the privacy of its users. Developed by researchers at the University of California, Irvine, TrackCOVID works by creating an anonymous graph of interactions. Every time a person gathers with others or goes to a public place, he or she can use the app to log contacts by either hosting or joining a checkpoint, which allows possible paths of virus transmission to be discovered.
