Challenges in hospital-acquired coronavirus disease 2019 (COVID-19) surveillance and attribution of infection source
Published online by Cambridge University Press: 02 August 2021
Abstract
We performed surveillance for hospital-acquired COVID-19 (HA-COVID-19) and compared time-based, electronic definitions to real-time adjudication of the most likely source of acquisition. Without real-time adjudication, nearly 50% of HA-COVID-19 cases identified using electronic definitions were misclassified. Both electronic and traditional contact tracing methods likely underestimated the incidence of HA-COVID-19.
