Here are a series of charts to give you a better view of the Coronavirus. Most of the charts are interactive and you are able to add countries, regions of the world, the world as a whole, income brackets, and other interesting data points.
Here are a series of testing charts for COVID-19.
Number Confirmed Deaths COVID-19
This chart shows the number of confirmed deaths due to COVID-19.How you can interact with this chart:
By default you see the death counts for 10 different countries. But this chart is interactive: by clicking on + Add Country you can compare the data for any countries in the world you are interested in.
How rapidly did the number of confirmed COVID-19 deaths increase in different countries?
Each country’s trajectory begins on the day when that country had more than 5 confirmed deaths. This allows you to make comparisons between countries.
Three tips on how to interact with this chart:
1. Clicking on any country in the chart highlights that country. If you click on several countries you can create a view in which you can compare several countries.
2. Any country you might not see immediately you can find via the ’Select Countries’ in the bottom left. Just type the name in the search box there.
3. To focus on the countries you highlighted click on ‘Zoom to selection’.
Number of confirmed COVID-19 deaths per day
• In countries that responded well to the pandemic the death count stayed low – South Korea is an example.
• In other countries – for example Italy, Spain, and the US – the number of confirmed deaths increased very rapidly for several weeks before the growth rate declined.
Daily confirmed COVID-19 deaths per million people.
It makes sense to adjust for the size of the population because the death count in more populous countries tends to be higher.
Total confirmed deaths per million people
Two tips on how to interact with Our World in Data maps:
1. You can drag the blue time-slider below the map to any other position – the map changes to the date you are interested in.
2. In all our maps you can click on any country to switch to the chart view and see its change over time.
Trajectory of confirmed cases between countries
• Spain and the US had particularly rapid outbreaks. Within two and a half weeks the number of confirmed cases reached 10,000 and continued to rapidly increase after that (as you can see, the US had 100,000 confirmed cases within 25 days after having the 100th case).
• In South Korea the speed of the outbreak was much slower, after 6 weeks there were 10,000 confirmed cases and the growth rate stayed slow even then.
What are the grey lines in the background? These lines show the trajectories for doubling times of 1, 2, 3, 5, and 10 days.
If the slope that a country is on is steeper than a particular grey line, then the doubling time of confirmed cases in that country is faster than that.
For example, there are several countries for which the slope was steeper than the ‘…every 2 days’ line – this means their case count doubled faster than every two days.
Number of daily tests per thousand people
There are extremely large differences between countries as this chart shows.
Some countries do very few tests.
What is counted as a test? The number of tests does not refer to the same in each country – one difference is that some countries report the number of people tested, while others report the number of tests (which can be higher if the same person is tested more than once). And other countries report their testing data in a way that leaves it unclear what the test count refers to exactly.
