The majority of countries in Europe are falling short on tracking coronavirus variants, such as those first detected in the UK, South Africa and Brazil - meaning more contagious strains are spreading undetected.
"In the European Union, we are strengthening our ability to identify and monitor new variants, but we are not yet there," the chief of the surveillance section at European Centre for Disease Prevention and Control (ECDC), Bruno Ciancio, said on Monday (15 March) during a public hearing in the European Parliament's health committee.
