The government is working to return to classes on January 7. There remains, according to the Corriere della Sera, an unknown state of health regarding the reopening of schools.

Thursday December 31 the Higher Institute of Health has published the first in-depth report on the infection situation in the 3-19 age group to provide a scientific basis for the reopening of schools.

The conclusions, in the 40-page document, are not final.

In the current state of knowledge, schools seem relatively safe environments also due to lack of data: “The impact of the closing and reopening of schools on the dynamics of the epidemic is not yet clear.”

For scientists, the decision to reopen on January 7 remains political, because “Schools do not seem to cause a significant increase in infections within them but, depending on the external context and the epidemiological situation, they can help slow or accelerate the spread of the virus.”
