Assessment of Risk Factors for Coronavirus Disease 2019 (COVID-19) in Health Workers: Protocol for a Case-Control Study [open pdf - 1MB]
From the Summary: "The spread of an emerging novel respiratory pathogen such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is accompanied by uncertainty concerning its key epidemiological, clinical and virological characteristics, particularly its ability to spread in the human population and its virulence. Understanding SARS-CoV-2 infection among health workers and identifying the risk factors for adverse outcomes are important not only for characterizing virus transmission patterns and risk factors for infection, but also for preventing the future infection of health workers and patients, for informing and updating infection prevention and control (IPC) measures at health care facility and national levels, and for reducing secondary SARS-CoV-2 transmission within health care settings."
