I’m seeing a bit of noise in the reporting, probably due to lag of a day or two in detection to reporting in the data. I just checked using the CSSE at Johns Hopkins University COVID-19 Data to March 8th, where the data lags the WHO’s Situation Reports by a few hours.
I also got an exponential growth rate of 0.15 with σ=0.06 per day for cases outside of China.
Looks like exponential to me, to a good degree of confidence. It will be a couple of weeks before one could say otherwise with any confidence.
