Thank you for the new thread.
@MarshaBradyo - from the previous thread discussion. Yes, your observations about other professions would have been true at that time (bear in mind it includes lab assistants, physio, IT etc, so a huge range of in/out of home working). That said, this new strain looks to be creating additional infections somehow, because the outbreaks appear to be spreading very much faster across areas than previous outbreak patterns. However it's spreading looks to have changed from previous variants, so depending on what that difference is, it may start changing the risk factors for various occupations. If that's the case, that ONS piece may be a bit out of date now. My personal opinion is that it should be monitored at least monthly, to spot changes that mighty affect guidance.
In terms of the pattern, for anyone interested (don't read if you'll become anxious from speculation, because this is only speculation based on the pattern I see). Look back at Swale in early October; it very suddenly gained new infections and was looking dreadful by early November. Fast forward to early December and this has spread throughout Kent, seeping into East London (already problematic) and Essex. Meanwhile early to mid November a tiny outbreak jointly in Roehampton and Wimbledon Common starts to spread. Over the course of mid November to mid December, those outbreaks have spread to encompass all of Kent and Essex, the majority of London (centre starting to fill in now), out into Surrey and down into Sussex. Places in the north with endemic infections took many more weeks to spread into the other towns, they only looked like large assess were affected because it took a long time to clear infections. Rulebreaking is everywhere to some degree, but the speed of spread looks different. To me, it's just got significantly more infectious somehow. I can speculate how the change in spike protein has caused this, but no evidence for my thoughts.
