How lockdown stopped the virus in Italy

Previous studies have shown that many severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases were tied to asymptomatic carriers or those who do not manifest symptoms of the viral infection. Now, a new study reveals that in the first Italian town hit by the virus, as much as 40 percent of the population had no symptoms of the coronavirus disease (COVID-19). The researchers at the University of Padua and Imperial College London revealed that many people in the town of Vo, northern Italy, and the first one to be locked down in Europe due to the coronavirus outbreak, had been infected with the SARS-CoV-2 virus, but did not display any symptoms. The results add to previous data that the number of those who had contracted the virus may be higher than what the official tally shows.
