COVID-19 Spread Map

This map is being passed around on social media.


While the map is technically accurate, it is a little misleading when you are not reading the information correctly. 

Here is the original source: https://coronavirus.jhu.edu/map.html?fbclid=IwAR0rpTf-yQ4BLgMIoiTzvZxynbo8JqBeiFm0Le9XSX7sT54-tqWUchdb32k

You'll note that not in every country does it show the distribution of the confirmed cases but instead a single dot to represent the total confirmed cases.  In Canada each dot represents the total for each province and not the distribution in that province.  Thus this is why it doesn't show any red dot in Toronto for example.  

This map from April 6th 2020 shows the distribution in Canada a little better than the Johns Hopkins map

So while the point of the original meme poster may be valid (as of writing this blog post https://www.worldometers.info/coronavirus/ has it that the USA is at 2,258,341 cases and Canada 100,148 cases) the map used can give the wrong impression.
