Diagnostic and Prognostic Biomarkers in SARS-CoV-2 Infections

Literature data document that SARS-CoV-2 RNA is present not only in the respiratory tract but also in the feces of infected patients, suggesting a potential additional route of transmission: the oro-fecal route. In this context, it becomes essential to have data on the use of serological tests in suspected SARS-CoV-2 patients and the presence of viral RNA in biological samples from affected patients, to quickly and reliably identify infected individuals and provide recommendations on the duration of patient isolation. In particular, such data could support the indication for contact isolation similar to that used for all highly contagious gastrointestinal infections, such as Clostridium difficile, with a longer duration than respiratory isolation. The objective of this study is to verify the presence of diagnostic and prognostic biomarkers in patients with SARS-CoV-2 infection.
