I'm very concerned about what is going on in France at the moment. Infections have crept back up to over 2,000 per day. That concerns me for two reasons:
1. We are probably going to have to reapply lock down measures in order to stop the same thing happening here.
2. My parents (got back from a three week holiday in Brittany last week) report that everything is more or less back to normal, except for mask wearing everywhere indoors.
The second point implies to me that masks aren't as effective in keeping the R number down as we had all hoped.
