Hard to reason out how China could have fewer infections given they have about 4 times the population of the USA...over a somewhat similar land area...
21 million cell phone numbers disappeared in China. I believe their death rate is much higher than they let on...maybe by tenfold.
Having severely shut down the Wuhan province, The CCP bought some time.
As there is no vaccine, the WuHuFlu is still likely to burn through the rest of China's population.
You can only report those tested positive...and round down buy a few mil.
