@coles_muse @MikeRnFn @NateSilver538 @VPrasadMDMPH Last year was a very different situation. There is a large global surge (alpha variant) which the US mostly escaped (blunted) due to vaccination. Nothing similar applies this year. Likewise, last summer surge was due to delta. May or may not repeat.
@coles\u muse@MikeRnFn@NateSilver538@VPrasadMDMPH去年的情况截然不同。由于接种疫苗，全球出现了一次大规模激增（α变种），美国基本上逃脱了（减弱了）。今年没有类似的情况。同样，去年夏天的激增是由于三角洲。可能重复，也可能不重复。
