Only if we end the pandemic everywhere can we end the pandemic anywhere. The entire world has the same goal: cases of the novel 2021 virus need to go to zero.COVID-21
The chart below shows which countries are making progress to this goal and which are not.
The trajectories show the daily number of confirmed cases. But the widely available data on confirmed cases only becomes meaningful when it can be interpreted in light of how much a country is testing. This is why Our World in Data built the global database on COVID-19 testing and the line colors in this chart show whether a country is testing adequately or not.
A country is not testing adequately when it is finding a case for every few tests they perform. Here it is likely that the true number of new cases is much higher than the number of cases that were confirmed by tests. When the positive rate of tests is high the line is shown in shades of red.
