No disease in the past 100 years has led to stay-at-home orders.
We are in completely uncharted territory here and pretending it will just go away (with or without a vaccine) will just result in the death toll continuing to go up and up - leading to the question, at what point does society in general become desensitised to it and stop caring.
Again... We have never developed herd immunity to a disease and our track record of eradicating viruses isn't even worth considering.
There is no back-to-normal. We are going to have to live (and die) with this virus for good now.
We have a virus that is more contagious and deadlier than anything we have faced for 100years and medicine, as it stands, is pretty much powerless (as the death toll shows).
There is no 'solving' this. There is only learning to live with it. And learning to live with it is going to take living a different way than we lived before.
The quicker the entire human race grasps this and stops the Trumpian head-in-the-sand, "it'll just go away" or that a vaccine somehow magically eradicates a deadly virus in half a football season. When no other vaccine, bar one, has ever worked and that took decades.
What a load of crap. We might not have eradicated diseases but we have come pretty close. Small pox almost globally non existence. Measles is nowhere near as prevalent as it used to be thanks to vaccines (and no thanks to Andrew Wakefield), the same for mumps and rubella. The more people vaccinated the less likelihood of the disease being able to spread. That's your herd immunity. It doesn't mean everyone is immune it just means someone with the infection is less likely to meet someone else who can catch it.
