Total confirmed COVID-19 cases, by source

Confirmed COVID-19 cases are compared for the three main data sources:
– Johns Hopkins University;
– World Health Organization (WHO) Situation Reports;
– European Centre for Disease Prevention and Control (ECDC)

Source: Johns Hopkins (2020); WHO COVID-2019 Situation Reports; ECDC (2020)

Note: The number of confirmed cases is lower than the number of total cases. The main reason for this is limited testing.
