Sites for tracking COV-19 numbers

For my numerically and geographically inclined friends:

Here are three of the good sites for keeping track of numbers of cases, deaths, recoveries etc. They will not exactly agree.

From the WHO site:

Then this one from Singapore-based CNA:

And this one which has a large number of tables and other representations of data. It is particularly useful for comparing information across different countries:

Also some curious facts-Myanmar, North Korea and Yemen are among the countries which have had zero cases by March 15.  Similarly for many sub-Saharan African countries such as Angola, Botswana, Tanzania, Zambia……

Some others like Nepal and Sudan have no cases now once the victims have either recovered or died.

PS: One should be careful about wording. Corona Virus is a general term which includes several viruses including COV-19. So we are more concerned about COV-19 now. SARS is another example of Corona Virus.
