No one can have proof because the data hasn’t been collected. Looking at the CDC sight you can download the actual deaths that are documented from flu. Then there are the estimate numbers, many times greater. The fine print says those numbers are based on a mathematical model.
I’m confused. You said the China Virus deaths are higher in number than Flu deaths. My understanding is there are about 30,000 deaths attributed to this years flu strain while the China Virus has according to released info about 7500 so far.
