Well, technically, influenza is not a coronavirus, but various forms of coronavirus are very widespread and common, and one form of them can cause what is termed the common cold (along with a rhinovirus that is the other cause of cold).
This one is different and appears to have been genetically altered in a lab and escaped.
Doctors who have treated corona patients have discovered that it's really a blood disease rather than a respiratory disease, and studies have shown that it affects those with A blood types much more severely that people with O blood types. And it also effects people who are deficient in zinc. I bet that if you combined the two, people with A blood types who are low in zinc, you'll quickly identify 90% of the people severely affected by corona.
Wherever it came from, they're obviously using it as a way to exert control and promote some agenda. It's still unknown who actually released this virus. Was it the Chinese or was it someone elsewhere trying to frame the Chinese? Someone attempting to start a war? Someone tied to Gates and the WHO (who strangely had that corona even months before this thing made the news)?
What's clear is that actual mortality rate is extremely low. They're admitted that 10x the number of people have had it than have been officially diagnosed/confirmed, which means that the actual morality rate is at least 10x lower.
