The real cases of Covid-19 in Italy could be equal to 5% of the population, or about 3 million: this is the probable estimate, according to the epidemiologist Carlo La Vecchia, professor of medical statistics at the University of Milan.
"If we think about an estimate of real cases, it is likely that today at least 5% of Italians are positive," La Vecchia told ANSA.
A percentage that translates into "a number between 2 and 4 million individuals, probably around 3 million".
Against the million known cases, there would therefore be "about 2 million unregistered cases, probably with few or no symptoms".
