Everyone says this, but it doesn’t seem to be true. I posted this two days ago in the OOT thread:
With the recent spike in cases in the South, it occurred to me to check something out with respect to the common argument that deaths are a lagging indicator of infections/cases. Thus when we see a spike in cases, we shouldn't expect to see a spike in deaths until several weeks later.
This may intuitively feel true, but empirically it has not been true, at least in places that have had major outbreaks. I looked through my data for the peak in the seven-day averages for cases and deaths of the worst hit countries and states. Most hit their peak in both within a few days of each other:
Countries:
Italy: Cases peaked March 26, deaths peaked April 2
Spain: Cases peaked April 1, deaths peaked April 3
France: Cases peaked April 9, deaths peaked April 8
UK: Cases peaked April 14, deaths peaked April 13
Early states:
Washington: Cases peaked April 9, deaths peaked April 10
New York: Cases peaked April 10, deaths peaked April 13
Michigan: Cases peaked April 7, deaths peaked April 16
New Jersey: Cases peaked April 7, deaths peaked April 21 (though there was a long plateau for both)
Connecticut: Cases peaked April 22, deaths peaked April 25
Pennsylvania: Cases peaked April 10, deaths peaked May 5 (this is the biggest exception)
More recently:
Illinois: Cases peaked May 12, deaths peaked May 13
Maryland: Cases peaked May 24, deaths peaked May 1 (?!?, also a long plateau for both)
Virginia: Cases peaked May 31, deaths peaked May 28
