You are assuming that someone who is not sick, has never been sick, and never will be sick is a “case”.

No, I am not. I am assuming that people who got the virus are a case. As you say they may not feel sick. But they are.
There is a professor at the College of London who studied at Oxford and Cambridge, who has determined that there is clearly a large group of people who are not even able to catch the virus at all. This group could be as high as 50% to 80%. In some countries its likely smaller, like Italy, while in other countries like Germany its likely at the top of the range. They don’t know why this is, genetics, diet, vitamin D? Know one knows. But there is clearly a group who neither has antibodies, nor is susceptible to catching the virus at all.
Here is the video explaining...
