You don't seem to understand the problem. If everyone gets infected, the deaths will be way higher or just as high. Anyways that's not even the problem, the problem is that this 'flu' is extremely contagious and without any measures taken it will spread extremely fast infecting 80-90% of the population in any country within months. No healthcare system can sustain that and would collapse. Do you not understand that?
Well of course if everyone gets infected deaths would be high, but what makes you think everyone
is going to get infected? How do you know this is going to infect 80-90% of people? And the economy will collapse if everyone is told to stay in doors for however long never-mind the hospitals. How long are we meant to self-isolate for? I don't think staying indoors for a few months is going to cut it and even that would be disastrous. If it's as extreme as you say then why isn't there a full on lock-down for everyone already? Telling people to just not go to the cinema or sporting events isn't going to do anything if everyone is still going to work etc. How often are we going to have to self-isolate for before the coast is clear? Is this going to happen everytime a new form of SARS appears?
That's what scientists are predicting. In the US alone: 'The CDC reportedly predicted 160 million to 214 million infections, 2.4 million to 21 million hospitalizations and 200,000 to 1.7 million deaths in the country. ' It's not 90%, my bad, it's more like 70%, my point still stands though.
''How long are we meant to self-isolate for?'' As long as we have to mate. 'Is this going to happen everytime a new form of SARS appears?' Yes if it's serious enough, quit crying about it, not everything has a good solution.
