Unfortunately this, just like many others, is inaccurate because it is only based on reported cases and so far America hasn't tested very many people
It's why I show the daily testing numbers and also calculate the RATE of testing for each state, so there's at least a reference for how states are doing comparatively.
---- Why is having accurate stats on the number of tests so important?
By definition, a confirmed case is one confirmed by a positive test for COVID-19. If your state isn't doing much testing, then you won't have many confirmed cases. However, there could still be a high number of people with coronavirus in your state, they just haven't been counted yet.
