A new study out of the University of Chicago has found that during the initial wave of the COVID-19 outbreak in New York City, only 1 in 5 to 1 in 7 cases of the virus was symptomatic. The research team found that non-symptomatic cases substantially contribute to community transmission, making up at least 50% of the driving force of SARS-CoV-2 infection. The results were published on Feb. 10 in the Proceedings of the National Academy of Sciences.
