It certainly is becoming apparent that the only way to open is to get
some form of immunity and without an effective vaccine, that comes by
people surviving the infection.
You can try to sugar coat it but that is the reality.
New Zealand got a lesson last week. One guy potentially infected a
couple hundred people (I haven't seen the real number of infections
but something like 280 were quarantined) in spite of sealing the
borders of the country. There was no immunity so one stray case
rippled through everyone he met and the people who met him met.
Without functional immunity, imagine that in the US where an infected
person can freely travel coast to coast in hours.
I was talking to my wife today. How would you "contact trace" everyone
who might have been infected by someone in a movie a week ago, in a
ceneplex with 12 theaters?
Imagine a ball game where people are shoulder to shoulder in the
stands, bathrooms, concourses and concessions.
John is the math wizard. If 20,000 people at a ball game then contact
5 more people who contact 5 more each(a pretty low estimate actually)
how many people are we talking about?
