A novel coronavirus (severe acute respiratory syndrome coronavirus [SARS-CoV-2]), has been causing a COVID-19 pandemic of acute respiratory syndrome in humans since December 2019. It appears to be similar in structure to the virus that caused the SARS-CoV outbreak of 18 years ago. However, in addition to the respiratory disorders, the COVID-19 patients might suffer extra-pulmonary disorders, including gut dysfunction or liver dysfunction complications, which show as gut–lung crosstalk. Fecal specimens should be considered as a source of detection of SARS-CoV-2 as one of the routine diagnostic tests in order to guide hospital’s liberation and release of quarantine of patients.
