COVID-19: A Retrospective Cohort Study of Nosocomial Transmission in a District General Hospital.

Background and objectives Since the outbreak of coronavirus disease 2019 (COVID-19) in the UK, there has been concern that a higher proportion of COVID-19 deaths among inpatients were a result of nosocomial infections. We sought to investigate the proportion of nosocomial COVID-19 infections within our hospital and patient outcomes within this category. Methods This was a retrospective cohort study of 616 patients admitted to the hospital and tested positive for SARS-CoV-2 through a polymerase chain reaction test with particular emphasis on 104 patients who were classed as probable or definite hospital-acquired COVID-19.
