When people present R0 as a property of the pathogen, you can take it as hot panicky air.

From wiki: "R0 is not a biological constant for a pathogen as it is also affected by other factors such as environmental conditions and the behaviour of the infected population."

Wiki also lists this number as the current R0 (though without a source, as far as I can see). Found this study too in attempting to answer your question: https://www.fil.ion.ucl.ac.uk/spm/covid-19/forecasting/

And learned the difference with Rt today (which some others are quoting, eg for Alberta), is that Rt is computed, while R0 is a guess based on a model, to try to normalize Rt so that it is more comparable over time and place. So I thought that was cool!
