Fatalaties for corona virus, as a percentage of hospitalization, are lower etc. But about 15% of the reported patients in China, end up hospitalized!
It's different because nation states are dealing with it as a man made lab virus...
It's why Russia closed their borders with China. It's why China chose to quarantine whole cities. These are the actions of leaders who have serious concerns.
Yes, the common everyday flu is killing more people... so why the extra measures? What would have to exist for these National Leader's choices to make sense?
I'm guessing the Chinese did NOT spend time, effort and money to develop a flu that's not as deadly as the everyday seasonal flu. This could be a one two punch virus - with the second one released later - or it could be designed to reinfect people - each time wearing down a person's natural defenses, or the real illness could 'go off' 6 month's after all symptoms have gone away. Could be a harmless 'carrier virus' that more virulent strains could be piggy backed onto...
We don't know.
All we know so far is this is NOT the way the Chinese OR any other countries would be responding based on relatively low death rates.
