Improve the ventilationEven with the use of air filtration systems, classrooms reduce the transmission of Sars-CoV-2 in the student community. The reiterate Centers for disease control and prevention (Cdc) Americans who monitored, between February and March, a sample of public schools, and the related transport for students, where resources were invested to renew the ventilation systems also with the latest generation technologies.
The study conducted by the experts of the Cdc involved 420 institutions, in urban and rural areas, and 11 strategies for ventilation in schools and on school transport were considered. The four most frequent were: the relocation of various outdoor activities; inspection and control of ventilation and air conditioning systems existing before the pandemic; keep doors and windows open when you can. Then, in some complexes, portable Hepa (High Efficency Particulate Air) filtration systems were used in the classroom and in the spaces where the students eat; then other schools also used fans.
“Securing resources for improved ventilation could reduce the transmission of SARS-CoV-2 in schools, prevent the transmission of other infectious diseases and lead to improvements in the health of students and school staff,” the American experts conclude.
“We have a few months ahead of us to secure schools with aeration and mechanical ventilation systems which, as I have been saying for two years and as a Spallanzani-Sapienza studio has also certified, are three times more effective than masks in protecting against Sars-CoV-2 infection. We need to be industrious ants now to ensure a more peaceful autumn. In fact, it is time to say enough to children with masks: it is a show that we no longer want to see“. So at time.news Salute Francesco Vaia, director of the Inmi Spallanzani of Rome, comments on the report of the American Centers for disease control and prevention (CDC). Vaia was the first to indicate one of the strategies to return to normality in securing social places. So modern ventilation systems also “in cinemas, theaters, on public transport, Italians – observes the director – will be happy to allocate a few points of GDP to this operation so as not to go back to the mistakes already made in the past”.
