Concerning an exponential rise in UK cases.
Rt goes to about 1.4-1.5 with a daily increase of about 5-10% in the Rt (that Rt is from Friday - it's Sunday, so some sources are saying current Rt rate is over 2. The graph of numbers reflects that it has gone over 2 (exponential).
The R number and growth rate in the UK
The map below is from last week (ended Friday, I believe), so does not include the past 2 days. Hopefully, the graph above is due to the "glitch" (about which little is known) but you can see that even before that, UK had quickly reached a level of new cases higher than that in May.
Covid cases and deaths today: coronavirus UK map
Sunday papers are often slow to update on science/health news, but there are certainly places to read about this. I am not familiar enough with UK journalism to know which MSM are reliable, but the BBC appears to have an explanation (not for the Rt which is studied entirely different to merely tallying cases).
Somehow, UK apparently missed out on reporting over 13,000 cases of CoVid and 49 deaths in September. I'm not sure I understand the reasons, exactly, or whether they know they've fixed the problem (the map linked above was from before this "glitch" was fixed).
Here's an article based on the pre-glitch (unfixed numbers) on which the Rt is based (some say the Rt will have to go higher after the glitch has been fixed - Rt is typically not based on the last 24-48 hours):
Coronavirus: Why are rates rising in some areas of England and not others?
As you can see, there's good research and analysis going on as to why this is happening, but we're seeing something similar in places like Montana and Utah. When CV first comes to an area, it often spreads rapidly and without restraint, and then pops into view as it reaches more vulnerable populations.
