Again, 0.021 percent as of September 26, which means two positive students for every ten thousand evaluated, if updated after Nicoletta-Ruffino’s studies, today it becomes a number two and a half times higher (0.052 per hundred, five students each). ten thousand). By the same reasoning, the schools involved in at least one infection today would be 2,800-2,900, or a third of the total 8,868 (9.2 percent if the positives are divided among the 40,151 school complexes of individual schools). “How can we deduce from these data that the world of education is not part of the contagion problem?” It is always the question of the conscious audience.

Azzolina: few infections at school. “But in the Babel Regions of rules”
On the Facebook page “Coronavirus, data and scientific analysis” doctors in physics and communicators Giorgio Sestili me Francesco Luchetta write: “The minister gives the numbers and says: ‘The school has not had an impact on the increase in infections if it is not residual.’ We wonder what sense it makes to communicate statistics of this type and in particular to give the percentage of school personnel who He has contracted the virus after just two weeks of activity. We wonder if such statements go more in the direction of propaganda than in the direction of correct information. “
Enrico Bucci is a biologist with a long career – a professor at Temple University in Philadelphia – who founded a company dedicated to the analysis of scientific data and in the period of confinement has become a heard voice in the interpretation of public numbers. Contacted by Republic On the question of “positive percentages in school”, he says: “After two weeks, you cannot speak of a negative or positive effect, you simply cannot speak of anything. The observation period is so short that there is no physical time to draw conclusions. The minister was gambled, in fact, said something nonsensical. The student population is a part of society that behaves like the population as a whole, no one today is able to say if these positive aspects are we sick at school or out of school The ministry, among other things, offers us numbers without telling us how it gathered them from a methodological point of view. How many are positive and observe if, compared to the new positive totals, over time the fraction It grows. Within the sample offered by the minister, however, there is everything and, therefore, we cannot know who got sick at school and who at a party. It is likely that the measures taken in schools are really useful. them and can be applied successfully, but reselling them in this way does not help to understand or build anti-Covid policies ”.
