The excretion patho-mechanisms of SARS-CoV-2 are actually unknown. No certain data exist about viral load in the different body compartments and fluids during the different disease phases. 

Findings show that SARS-CoV-2 is present in peritoneal fluid at a higher concentration than in respiratory tract. Detection of SARS-CoV-2 in peritoneal fluid has never been reported. The present paper represents the very first positive result describing the presence of the virus in peritoneal fluid during an emergency surgical procedure in a COVID-19 sick patient. This paper thus represents a warning for increasing the level of awareness and protection for surgeon especially in emergency surgical setting.
