// Or that the reason for more cases being diagnosed, could be because of more tests being done, and does this necessarily mean that more people are contracting Corona? //
People *have* put this question to politicians, scientists, etc. The answer is that there are two separate effects and it's perfectly possible to separate them from each other. Right now we are reporting around 4,000 cases/day, which is (superficially) comparable to April but could clearly be related to a far greater rate of testing since then. On the other hand, testing capacity has been fairly flat since June (climbing up a little in September, and processed tests are increasing). As a rough estimate, though, there are only around 55% more tests per day at the moment than there were in mid-August. But in that time there has been a 400% increase in the number of positive tests, which is clearly far faster than can be accounted for solely down to increased testing. Put simply, the virus is clearly spreading more quickly now than a month ago.
