Viral Cultures for Assessing Airborne Transmission of SARs-CoV-2: a Systematic Review

We plan to systematically review the evidence for airborne transmission with high-level confirmatory studies of infection that include viral culture or longitudinal serial PCRs with or without gene sequencing. To assess the transmission potential of airborne transmission of SARS-CoV-2, we aim to address the following questions:Are airborne 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 infectiousness and Airborne PCR cycle threshold (Ct)?Is there evidence of a chain of transmission that establishes an actual instance of airborne transmission of SARS-CoV-2? What circumstances might facilitate infectious viruses being airborne over long distances?
