Right now there is no exist strategy. There are possibilities though.
Assuming a vaccine doesn't appear, then we're left with herd immunity through community infection. There are problems with that though, because it's not yet clear whether infection with the COVID-19 virus even makes a person immune to future infection.
Amidst all the uncertianty a vaccine is our best hope. Personally I'm assuming this will be with us in some shape or form for many years.
