From the press release:

While some people who contract SARS-CoV-2 infections never experience any symptoms, there remains disagreement about what proportion of total infections these cases comprise. A study by researchers of the Institute of Social and Preventive Medicine of the University of Bern suggests that true asymptomatic cases of SARS-CoV-2 comprise a minority of infections.

 

COVID-19's silent spread - A UF/EPI professor helped develop a model that estimates slightly more than half of COVID-19 transmission is due to people with no symptoms. A third or more of these cases would need to be isolated, in addition to most symptomatic cases, to quell the pandemic

A UF/EPI professor helped develop a model that estimates slightly more than half of COVID-19 transmission is due to people with no symptoms. A third or more of these cases would need to be isolated, in addition to most symptomatic cases, to quell the pandemic.

More than half of COVID-19 transmission is driven by people who show no symptoms, according to new research published on July 6 the Proceedings of the National Academy of Sciences. The findings could directly influence the design of test-and-trace containment policies that aim to lower the rising numbers of infections in the United States.

From the abstract:
Mounting evidence suggests that there is an undetected pool of COVID-19 asymptomatic but infectious cases. Estimating the number of asymptomatic infections has been crucial to understand the virus and contain its spread, which is, however, hard to be accurately counted.
