From The Spectator's Covid-19 newsletter:
The rise in Germany’s R-number – from 1.8 to 2.9 – is big news in Britain. But not in Germany. Why?

Because the local outbreak in North Rhine-Westphalia at a meat processing plant is being handled, so far, without the need to lock down. Cases are so low now in Germany that even a local outbreak is capable of pushing the national R-number up.

Robert Koch Institute, which produces Germany’s R-number: "Since case numbers in Germany generally low, these local outbreaks have relatively strong influence on value of R-number." A caveat rather ruins the story. Idea of German second wave gets a lot more clicks on social media
