MI officials finally realised data: They show a very different picture instead of that attested by Gandini and others in what appears to be a very misleading study, as I will show. Thread.

First of all data:

Now you can figure by yourself incidence in schools until 7/11: The study did not disclose them.

In Blue the high school plot in the study, in red the new plot from data. Much higher incidence in Umbria Piemonte Toscana and Molise!

Very strange choice to use in the study data up to 7th November.
(Extended All Saints holiday and High school online from Dpcm 25 October).
If you plot data up to 1th November almost every Region has higher incidence than population.
Only Campania has a plain lower incidence !

What about students in Lower schools: The new plot shows a slightly lower incidence than population, even if higher that in the previous plot.
Is it reassuring? Not really as we will see in the next tweet.

Teachers in Lower schools have a very high incidence, much higher than high school's teachers and population.

So lower incidence in pupils seems due to undertesting because of their asymptomatic tendence. On the other hand they can trasmit as stated by chart and by research.

So disclosed data seem to show a clear evidence of trasmission in Schools in Italy at reopening in September:
