“About 40 percent of patients with positive results had no symptoms of the disease,” the researchers said.

The results of the study also show that the virus was in patients for an average of 8 to 14 days. Thus, evidence has been found that mass testing combined with the isolation of infected individuals can quickly stop outbreaks.
In the town of Vaud, which has a population of about 3,200 people, a strict quarantine was imposed for 14 days after the first death in Italy from coronavirus on February 21.
