bug in the last 2 weeks. In other words, if the virus has been with us a long time, then the majority of people that have it now have gotten in it the last 2 weeks. There is no large group of people that have had a ton of mild cases and are sitting out their with antibodies. That is not how exponential growth works. The new cases far outweigh old cases. The data curves tell us that this disease is progressing exponentially.

The known cases are 20 to 50% of the true cases and not much more than that, but they are all mostly new, just 50 to 80% of cases are asymptomatic or mild.
