Researchers from the University of Cassino and Basso Lazio have made a video to explain how Covid-19 spreads inside school classrooms.
Are schools a safe place? Is it possible to contract Covid-19 in classrooms despite the masks and social distancing imposed by school authorities? These questions have been accompanying (and disturbing) politicians and many parents or relatives of school-age boys and girls for months. In an attempt to provide an authoritative answer, researchers at the University of Cassino and Lazio Meridionale have used a statistical model called AIRC (Airbone Infection Risk Calculator). This is an algorithm that determines the risk of Covid-19 infection in indoor environments. The AIRC model takes into account many variations: the professor speaking loudly or with a microphone, the windows open or closed, the type of mask worn. The result is a very accurate calculation of the risk of Covid-19 infection in classrooms.
Covid-19 in school classrooms: how does contagion occur?
This is not the first time that researchers have used statistical models to calculate the risk of Covid-19 infection indoors. Already during the first pandemic wave, MSC Software – an American company specialising in data processing and three-dimensional rendering – created a simulation showing the spread of the Coronavirus in an underground car. The study was coordinated by a team of virologists and researchers from the University of Leicester. The simulation was very accurate and compared the risks with and without the mask (WATCH VIDEO HERE). Of course, the results of the rendering showed that the probability of infection is much higher when users do not wear a mask and do not respect social distancing.
