Instead of waiting for the test result, Citizen Assisted Contact Tracing starts contact tracing using citizen computing resources when a person first has concerns, tracing is well underway BEFORE the person has even arrived at a centre to get tested.
High risk people (aged care workers, family members etc.) can choose to receive Early Notifications, warning them to take care BEFORE the test result is out.
Citizen Assisted Contact Tracing can perform the bulk of the contact tracing workload automatically and anonymously, freeing up human contact tracer to supervise its operation and handle difficult cases.
