Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
This work aims to assess the feasibility of performing COVID-19 RNA tests in hospitals and communities experiencing SARS-CoV-2 virus outbreaks, to ultimately provide recommendations for hospitals with so-called fever clinics. In China, these specialized clinics within a hospital specifically receive outpatients with fever symptoms. A team with expertise in the Exposure Analysis and Critical Control Points (EACCP) framework identified potential infection routes during the testing for SARS-CoV-2, then constructed and tested flow diagrams, which were confirmed under actual conditions, demonstrating the feasibility to carry out in hospitals with fever clinics. The team determined critical control points to mitigate the exposure risks at each control point. The sampling and inactivation steps of clinical samples in fever clinics appeared to be associated with particularly high-risk levels of exposure to SARS-CoV-2. Moderate exposure levels were associated with storage and transportation of samples for inactivation; Low-risk levels associated with the transportation, storage, and detection steps after inactivation. To minimize infection risks for personnel, we proposed optimized processes to carry out SARS-CoV-2 RNA tests in hospitals with fever clinics in China. The high risk of SARS-CoV-2 exposure during procedures preceding testing is the sampling and biological inactivation; Simultaneously, full personal protective equipment and BSL2 laboratories in fever clinics or mobile BSL2 laboratories could reduce the risk. Implementing the EACCP framework could facilitate rapid responses to outbreaks of emerging infectious diseases.
