COVID-19 Countries Trends

These graphs work best on a computer. Phones, not so well. Phone users: check out the blog.

These graphs are interactive (and not very useful or intelligible if viewed without interacting). You can click-and-drag to zoom, single-click on a particular item to turn it on or off, or double-click to show just that item.

Severity

The following graph attempts to show broadly “how bad” the epidemic is in each country, based on daily cases. It does this by multiplying-daily-cases-per million (DCPM), by the week-over-week growth factor in new cases (DCPM and growth are graphed separately farther below). Over 100 is a “severity warmspot” (bad); over 200 is a “severity hotspot” (very bad). Here are the top 20 countries::

And the same graph with all countries:

Total Cases

Daily Cases

Daily Cases Per Million

To really compare the numbers of different regions, we need to adjust for population. Hence “daily cases per million” (DCPM), which lets us see how relatively bad a region has it. I define a region as “warm” if DCMP is more than 100, and “hot” if DCPM is more than 200. The top 20:

And the same graph with all countries:

Daily Cases Trajectories

The next graph shows the relative trajectories in daily-cases-per-million of the countries, in days since each country reached 100 DCPM (those that haven’t are not shown). So each country’s graph is shifted in time, so they align horizontally at the moment they reached 100 DCPM:

Daily Cases Growth

This next graph is the “rope chart,” which shows the daily growth of new cases each region. This allows to predict the direction a region is headed. When a line crosses zero headed downward, that region has turned the corner toward recovery. I define a region as “warm” if growth is greater than 1%, and “hot” if growth is greater than 5%. Remember that you can double-click a name at the right, to see a graph of just that region. Here again you’ll probably want to zoom in with click-and-drag to see the details better:

And the rope chart for all countries:

These graphs are similar to the rope chart, in that it shows percent growth. But rather than fitting a broad trendline, they use a smoothed moving average, to show more of the fine details of the trajectories of each country. The graph below shows growth for the DCPM-hottest countries only:

And this is the same graph for all countries. Since it shows all countries, this is mostly just a snarl unless you double-click the legend to select a particular country:

Worldwide Daily Cases

Daily Deaths

Daily Deaths Per Million

Here are “daily deaths per million” (DDPM), which lets us see how relatively bad a region has it, in terms of daily deaths. The top 20:

And the same graph with all countries:

Deaths Growth Rate

The graph below shows growth for the DDPM-hottest countries only:
