UnViral Cultures for Assessing Fomites Transmission of SARS-CoV-2: a Systematic Review

We are updating the evidence on fomite transmission using the highest quality evidence from such published studies. To assess the transmission potential of Fomite transmission of SARS-CoV-2, we aim to address the following questions: Are fomite samples infectious? If so, what proportions are infectious, and what is the distance and duration of infectiousness in the air? What is the relationship between Fomites, infectiousness and PCR cycle threshold (Ct)?Is there evidence of a chain of transmission that establishes an actual instance of fomite transmission of SARS-CoV-2?
