You are assuming those 15,000 people who died WITH the virus, actually died OF the virus. This would appear not to b the case. US doctors have shared documents which instruct them to code a death as covid-19 even without a positive test result. Deaths are also counted as covid without it being the primary cause of death. Certainly looks like this has been happening in other countries as well. Doesn't allow for a great deal of confidence that we are being given accurate information.
