Divide deaths today by confirmed cases two weeks ago.
So according to this article from April 6 (roughly 2 weeks ago), https://gazette.com/news/by-the-numbers-coronavirus-in-colorado/article_432487ae-661f-11ea-b421-ffbd6dcb3c02.html
5,249 cases
179 deaths
Mortality rate of 3.4%
Current numbers (from https://covid19.colorado.gov/data/case-data)
10,447 cases
486 deaths
Mortality rate of 4.6%
Which is the trend that I am seeing. Mortality appears to be increasing ... at least for Colorado.
Thus my original post / question.
