Our results indicate that the number of notified cases of COVID-19 is rapidly increasing in the EU/EEA and the UK. The observed trends in the cumulative incidence of COVID-19 suggest that the pandemic is progressing at a comparable speed in all countries. This is despite countries being at different stages, variations in national public health responses, and possibly different case definitions in countries and different protocols for selecting patients that must be tested for confirmation of COVID-19, including catch-up testing.
