COVID-19 transmission: a rapid systematic review of current knowledge

Objectives The objective of this study was to identify the potential and definite sources of transmission of coronavirus disease 2019 (COVID-19). Methods Due to time constraints and the acute nature of the pandemic, we searched only PubMed/MEDLINE from inception until January 28, 2021. We analyzed t...

Symptomatic human-to-human transmission remains the driver of the epidemic, but asymptomatic transmission can potentially contribute in a substantial manner. Feces and fomites have both been found to contain viable virus; even though transmission through these routes has not been documented, their contribution cannot be ruled out.
