That 235 figure was old then.........I wonder how old this "new" 277 is?
That is a growth rate of 2.8% per day.
That is equivalent to an exponential growth time constant of 36 days. If the ratio of deaths to cumulative cases remains .92, then this is consistent with the middle growth curve and a patient lifetime of just over 3 days. The total number of cases should be about 301.
See plot at: Marburg Growth Plot
What is disturbing is that nowhere that I can remember did they ever indicate there were even 277 active cases.
