Calum Semple - the efficacy of mass testing in Liverpool - a podcast by BMJ Group

The government has decided to pursue a strategy of mass-testing in Liverpool, in a pilot to see what effect that has on containment of corona virus.

A lot of criticism has been levelled at the scheme, from the sensitivity of the lateral flow test used, to whether this is screening and should be referred to the national screening committee to be evaluated.Calum Semple, professor of child health and outbreak medicine at the University of Liverpool is evaluating the project, and joins us to explain what we can understand from this - how initial data shows the new testing regime is reaching more of the population, and why he thinks this is a public health intervention, not a personal screening test.
