Fomites and the environment did not have an important role in COVID-19 transmission in a Brazilian mid-sized city

Abstract It is not clear if COVID-19 can be indirectly transmitted. It is not possible to conclude the role of the environment in transmission of SARS-CoV-2 without studying areas in which people transit in great numbers. In this work we aimed to better understand the role of environment in the spre...
