Population-Wide Testing of SARS-CoV-2: Country Experiences and Potential Approaches in the EU/EEA and the United Kingdom [open pdf - 0B]
From the Key Messages: " Different population-wide testing approaches have already been used in various countries, including household testing, individual testing and the testing of incoming travellers, irrespective of whether or not they are displaying symptoms.  Factors that need to be considered prior to implementation of any population-wide testing strategy which is to include all individuals are the epidemiological situation, costs, logistics, technical feasibility, resource availability, contract tracing capabilities, barriers to testing, potential false positivity and timely notification.  Population-wide testing strategies can complement other public health measures and are more effective when paired with case isolation and contact tracing."
