COVID-19~Worldwide estimates for Ro in 2020

We se the results in our previous post to calculate worldwide estimates for Ro in 2020 using data up to mid-August 2020. We obtain the following table: For more countries see: COVIDWorldAllCasesCPMNZcorr Notes: The date and number of cases are when r* was calculated.
