A screenshot from the Johns Hopkins Coronavirus COVID-19 (2019-nCoV) dashboard:
It's pretty grim: the US past 16,000,000 cases, and on the verge of 300,000 deaths.
But the real shock is in this graph for case totals, with December 11 suddenly spiking beyond anything we've seen yet:
That shows 1,489,000 confirmed COVID-19 cases in 24 hours. More than double recent case counts, and on a weekend when counts are lower than usual.
I'll try to find the reasons for this, but for the moment I'm just stunned.
Update, Sunday morning: The dashboard this morning shows that Saturday's case count was a "normal" 623,311:
I'm guessing that the Friday spike is the result of delayed reports, probably from Turkey (the only country on the dashboard showing a similar spike on Saturday). JHU's COVID-19 Overview for Turkey seems to confirm this, with a record high of 981,514 cases in the week of December 6-12. Thanks to the commenter who spotted the Turkish spike.
