NEW: New York City has just issued an advisory for everyone to wear a mask in public spaces because COVID levels are high in all 5 boroughs.
kdnyhan@luckytran that's good and I hope it helps, but, er, haven't all five boroughs been at high CDC community level for a while, since before Thanksgiving? Maybe they went down and back up and I didn't notice.
@kdnyhan They’ve been up and down at various points. This is the first time all 5 are high at the same time. That said we are vastly undercounting COVID tests (we aren’t counting home tests), so likely the real “Community Levels” have been high for a while, as the hospitalizations component has been constantly high, while oddly the number of positive cases has fluctuated (likely a testing issue).
