Abstract
Transmission via fomites poses a major dissemination route for many human pathogens, particularly because of transfer via fingertips. Here, we present a protocol to investigate direct transfer of infectious agents from fomites to humans via naked fingertips. The protocol is suitable for pathogens requiring highest biosafety levels (e.g., SARS-CoV-2). We used an artificial skin to touch a defined volume of virus suspension and subsequent quantification of infectious entities allows quantitative measurement of transfer efficiency and risk assessment.
