COVID-19: Daily new confirmed cases vs cumulative cases

The line is blue when the rate of positive tests in a country is low – this means a country performs many tests relative to the size of the outbreak.
Red indicates a high positive rate of tests. This suggests that the true number of infections may be far higher than the number of confirmed cases.
