“We have not seen an urgent enough escalation in COVID-19 testing, isolation and contact tracing, which is the backbone of the response…We have a simple message for all countries: Test, test, test. Test every suspected case. If they test positive, isolate them and find out who they have been in contact with two days before they developed symptoms, and test those people, too.”
