Testing and contact tracing are standard tools for controlling the spread of COVID-19¹. Their effectiveness hinges on a sequence of processes encompassing testing coverage and timeliness, testing quality and speed of reporting, contact tracing speed and comprehensiveness and compliance with advice given^2–6. We optimized this sequence of processes in the context of a public health program targeting around 33,000 higher education students through a combination of low barrier PCR testing with rapid turn-around-time, close integration of testing and tracing teams and IT infrastructure, community engagement and the implementation of bidirectional contact tracing by extending the contact tracing window from 2 to 7 days before symptom onset or test of the index case. We anticipate this combined intervention to help improve epidemic control.
