States are working on a reopen plan, a bunch of medical research companies working on vaccines and treatments, and the governor of the hardest hit state hasn't even officially closed schools for the remainder of the current semester. No shot the country is in quarantine til 2021-22 or that schools won't be back until 2022
When the process of reopening begins, there will still be strict social distance guidelines, mask requirements, no large gatherings, etc and that can last 6-12 months but no way they keep strict regulations til 2022.
