I have been asked to write about the new outbreak in Germany when the discovery of a cluster of over 1,500 new infections at a meat-processing factory caused R to jump up to nearly 3 for a couple of days.
The article with the title Coronavirus: Germany’s new local lockdown is a warning not a disaster appeared in The Conversation today.
The blog is changing its location to:
although the old address, statisticallyinsignificant.uk will continue to work. This is to make it sound more international, as it is not only a blog about the UK, but also other countries.
Please continue reading and supporting it – if you find the blog interesting or useful, please do let me know – I really like receiving e-mails. Please contact: firstname.lastname@example.org
We are now entering a new phase of the coronavirus epidemic in which the numbers of newly infected people are small but there are still many susceptible individuals. The virus is, unfortunately, not going away, but the outbreaks will now change their character. Instead of a single large growing epidemic wave, we are likely to see smaller – but still substantial and potentially lethal – outbreaks.
Epidemiologists use models to understand the details of viral transmission, and they are now talking about a new number, K, in addition to the famous number R. I have written an explanation of why K is important for The Conversation, Is the K number the new R number? What you need to know. A more technical description is available on this blog, under the title of What is the number K?
By the way, the readership of my articles in The Conversation has now crossed the 500,000 number, including well over 300,000 readers for the second wave article. Thank you all for your support!
