This process is not very exact and also the particular date away from the fresh new peak really should not be taken seriously, however it is clear that occurrence become falling until the lockdown. This is so that obvious that it is obvious even in all of the-trigger mortality investigation, which have the newest trouble out-of excluding just deaths on account of COVID-19, however the advantage of becoming large-quality since deaths are recorded by day out of dying rather than because of the go out from declaration.

Unfortuitously, getting because the clueless as ever, the epidemiologists whom advise the new French authorities still don’t appear so you’re able to has actually received new memo even cuatro days later. In fact, in the a newsprint it recently penned on host training patterns they intended to predict this new short-term progression of epidemic, it note that all of them “over-imagine the latest height as lockdown”, but allege it is because the new date of your own lockdown “could not had been forecast”, which is of course maybe not the rationale as again the level out-of attacks try attained until the lockdown. By using other glance at the graph to the nation as a whole, it is also interesting to note you to definitely incidence reach rise once more on two weeks until the lockdown is lifted toward December 15. You could claim that it’s because people visited relax and you can this shorter conformity, you usually do not truly know can, regardless of if that have been genuine, it will be the capabilities of genuine lockdown you to we have been trying to find, perhaps not a theoretic lockdown in which compliance remains the same throughout the.

Here is a chart on the report , which shows the ratio of people in the The united kingdomt one to checked positive for the reason that survey: For people who go through the point quotes, the newest peak is actually reached during the times ranging from November 8 and you will November 14, nevertheless confidence durations of your guess overlap for the month ranging from October 17 and you may November 21, therefore we are unable to exclude the latest theory it absolutely was hit before lockdown already been. But no matter when exactly the peak try reached, what is actually certain using this chart is the fact that growth rate regarding positivity arrived at failure long before the fresh lockdown been, so there is the reasoning to think you to definitely occurrence could have fell also in place of a beneficial lockdown.
