How much of that drop is because of the change in threshold of PCR testing, or do to the overall reduction in testing? Personally I think the testing has been poor since the beginning and we shouldn't trust the numbers we currently have. If the numbers change dramatically in the near future, why should we trust them? Or maybe the truth is that the numbers that come in April are the actual truth and what we have seen is do to failures in testing.
