For instance, even a single person, without any symptoms, is capable of spreading the SARS-Cov-2 virus to large numbers of people. Without widespread testing, such people cannot be identified. To prevent this fast-spreading virus from taking control of the

The exact mechanism of spread of the SARS-CoV-2 virus in the community has so far been unclear. Droplet spread by coughing and sneezing has been the conventional explanation.
