Oh. I think we are talking about a least a year or more before things get back to normal.
without readily available testing and no vaccine, the risk of going back to pandemic will be there
I think we are talking about stages. For example, once test are available I think employers will be able to let worker who test negative to return
But I am afraid large enclosed venues like concerts and trade show will have more difficult time preventing them from becoming a hub for another outbreak. How can you put 15-20K people in an arena and not have carriers in the group?
Restaurants and bars, assuming they can survive now, will have a more difficult time given they rely of crowding on Friday and Saturday nights. I think it will be a long time before health departments will permit bars from being 3 of 4 deep.
Widespread testing access will greatly help the first stage. But until a vaccine is available, I suspect it won't be business as usual
