If that was true, we’d probably be seeing a lot more deaths in the other countries that aren’t prone to hding the truth - so far the mortality rate outside china doesn’t seem that concerning.
the virus has been going in China for over 3 months - also sanitation is not exactly good, maybe not so good, maybe really terrible, maybe unbelievably horrible.
Covid19 has just reached outside of China in the past few weeks The sanitation is good as are the medical practices with people seeking out western medicine - unlike China were the medicines are expensive (like a week’s wages) and traditional Chinese medicine is cheaper.
We’ll see in a few months if the West fares better.
