So, as a bit of a comparison (figures all taken from wiki, so may not be 100% accurate):

UK cases from 28/02/20 (when we were on 20 cases)

47 (Today)
These are new cases, not total number of cases, and it does suggest we are on a bit of a slower trajectory than other European countries- and I do think we are testing widely. There are obviously some undetected cases in each country, but I don't think there are loads in the UK (there are more in Italy).
This to me is actually quite encouraging from a UK point of view- although the next few weeks are obviously super critical.
