Currently we have no idea how many people have had covid. We have a good idea how many have died, but no country has managed to do the kind of testing that would give a good indication of how many people have been infected. Do 2% of people getting it die, or 0.2%, or 0.02%? Testing 1 million people at random across the country will give good results of not only how deadly it is, but also how likely it is to spread in different areas of the country.
