@MichaelTWorley @wsbgnl I don't know where to find a national Rt chart but most of the state charts I've seen show Rt steadily increasing back up toward 1 (though still below). Once it reaches one the cases will stop declining. Hard to tell when. Might be a few weeks, or months (months=VERY low cases)
@MichaelTWorley@wsbgnl我不知道在哪里可以找到全国Rt图表，但我看到的大多数州图表显示Rt稳步上升，回到1（尽管仍在下方）。一旦达到一级，病例将停止下降。很难说什么时候。可能是几周或几个月（几个月=非常低的病例）
