The numbers are probably not accurate, but there is no place where the numbers are accurate. Case fatality rates go from less than 1% to more than 10%. In France, on the official website where they give the numbers, it is clearly written "we don't test everyone, the actual number of cases is higher", and deaths are "of COVID-19 patients dying in hospitals". All numbers are made up, because there is no way to know the actual numbers.
And don't tell me that anything after January was China's fault. It is not like governments around the world didn't know what happened there. Maybe the general public wasn't well informed but it is trivial for a government to be aware of an event of such scale. No, China may be to blame for the initial cases, but for the pandemic phase, it is completely our fault.
