Incidence of SARS-CoV-2 is lower among students than in the general population.

Bubble graphs of SARS-CoV-2 incidence between September 12 and November 7 among 6–13 years old (A) and 14–18 years old (B) students and among teaching and non-teaching staff members (C) in Italian regions and autonomous provinces compared to the incidence in the general population. Size of bubbles is proportional to the measured incidence in the analysed school populations. The 45° line indicates equivalence between general population and school population incidence. Bubbles are color-coded in a green-yellow-red gradient proportional to the value of the ratio between the analysed population and the general population.
