I have been collecting the data from the CDC which is dated to the estimate d time of infection. This data shows new infections being attributed to da tes up to a month ago. This both raises the numbers for older data and low ers the numbers for newer data. It also invalidates the newest data as bei ng incomplete.
Constructing a graph from the most recent curve up to the peak infection ra te gives a very consistent exponential line with a slope of 0.19. I will n ote this number and update it each day as the CDC releases new data. The d ata peak is 3/13 for data of 3/24 and has moved from 3/9 in data dated 3/19 .
Unfortunately this method has a much longer lag time from actions to fight this disease.
