It seems there should be a third statistic tracked for those who are still sick, but have not yet recovered.

That’s the correct way to look at it. Should look at it as follows: total cases = # recovered + # dead + # confirmed cases who are sick. We’ll call it n.

Then the correct %s are # recovered/n × 100, # dead/n × 100, and # confirmed cases not dead or recovered/n × 100.
