Anthony Costello, a UK paediatrician and former director of the World Health Organization (WHO), said he had personally written to the chief medical officer, Professor Chris Whitty, asking for testing to continue in the community.
“The key principles from WHO are intensive surveillance,”
he told the Guardian. “You test the population like crazy, find out where the cases are, immediately quarantine them and do contact tracing and get them out of the community. This deals with family clusters. That’s the key bedrock of getting this under control.”
