You can disagree, but it's true. I'm not against testing as a whole, btw. The only people who need testing are those sick with it and those who are at significant risk. There might be correlation with countries that do a lot of testing and them dealing with it well, but that's not a direct result of the testing. Those countries have also implemented actual strategies to stop the spread, like enforced quarantine.
More health officials are coming out and are saying stay at home, don't try to get tested. It makes absolute sense. Do you really want valuable medical resources used up just to confirm that some guy with a fever and a cough has the coronavirus, even though you can't do anything to help him, and he'll just be told to go home anyway?
