Hand and surface viral load strongly correlated with COVID-19 infection risk in UK households

A National Heart and Lung Institute, Imperial College London study has confirmed that hands and surfaces could potentially transmit SARS-CoV-2 in a household setting. Published in The Lancet Microbe, the study, “Risk factors and vectors for SARS-CoV-2 household transmission: a prospective, longitudinal cohort study,” focused on pathways of physical and surface contact. Aerosol transmission was not investigated and was not in any way excluded as a means of transmission.
