Operation Moonshot: rapid Covid test missed over 50% of cases in pilot | World news | The Guardian

A rapid coronavirus test at the heart of Boris Johnson’s mass-testing strategy missed more than 50% of positive cases in an Operation Moonshot pilot in Greater Manchester, the Guardian can reveal.

The 20-minute tests, on which the government has spent £323m for use with hospital and care home staff with no symptoms, identified only 46.7% of infections during a crucial trial in Manchester and Salford last month.

This means that many of those carrying Covid-19 were wrongly told they were free of the virus, potentially allowing them to infect others.
