Some may end up with Long-COVID after asymptomatic infection. Chart is to end of Jan, 3 mill, in a pop of 4.4 mill. Line graph of approximate cumulative infection count in Albe
It is not safe to reopen with transmission so high, hospitals overwhelmed and surveillance all but cancelled. Wear the best mask you can, delay optional interactions if possible a few more weeks. Insist and clean, safe air.
