Italy closing all schools nationwide until march 15 to contain coronavirus outbreak

That's not accurate. While Italy has taken significant measures to contain the spread of COVID-19, it did not close all schools nationwide until March 15.

On February 4, 2020, Italy's Ministry of Education, University and Research announced that all schools in the northern regions of Lombardy, Veneto, and Piedmont would be closed until February 22 to contain the spread of the virus. This was later extended to March 1.

On March 4, 2020, the Italian government announced that all schools in the entire country would be closed until March 15, except for those in the autonomous regions of Valle d'Aosta, Friuli-Venezia Giulia, and Trentino-Alto Adige/Südtirol, which had already been closed earlier.

The closure of schools was part of a broader package of measures aimed at slowing the spread of the virus, including restricting travel, closing non-essential businesses, and increasing testing and contact tracing.

It's worth noting that the Italian government has taken a series of measures to mitigate the impact of the pandemic on education, including providing online learning resources and extending the academic year.
