Whatever the UK Gov #COVID19 strategy might be, mass testing for infection only works together with 'contact tracing' in the early stages of an outbreak, and not in the face of widespread transmission. A this stage, infection mass testing is unlikely to reduce mortality. (1/2) https://twitter.com/carolecadwalla/status/1245394675432853506
Mass testing for past infection (serology) doesn't reduce mortality either. It might help getting the economy (kind of) restarted, but the logistic, moral and ethical implications of allowing only the 'infected' to resume a 'normal life' may not be fully appreciated yet. (2/2)
