Report 16 - Role of testing in COVID-19 control
https://www.imperial.ac.uk/mrc-global-infectious-disease-analysis/covid-19/report-16-testing/

Widespread PCR testing in the general population is unlikely to limit transmission
more than contact-tracing and quarantine based on symptoms alone, but could allow
earlier release of contacts from quarantine. Immunity passports based on tests for
antibody or infection could support return to work but face significant technical,
legal and ethical challenges. Testing is essential for pandemic surveillance but its
direct contribution to the prevention of transmission is likely to be limited to
patients, HCWs and other high-risk groups.
