Hi everyone,
Can covid-19 survive all the biological and physico-chemical inhibition factors found in digestive system such as lysozym of saliva and high acidity of stomach to reach intestine?
This is an important issue to answer the question of the possibility of contamination by intaking a covid-19 -contaminated food.

thank you for sharing these links. Unfortunately, In both papers, there isn't any answer to the questions asked in this discussion.Here I will cite a paragraph from the second paper concerning this issue.
" SARS-CoV-2 transmission from person to person occurs mainly through direct contact or through droplets from an infected person coughing and/or sneezing (50). However, SARS-CoV-2 nucleic acid has been detected in the stool of COVID-19 patients in multiple studies (25, 69). Further research also found that some patients remain positive for fecal virus nucleic acids for a long time after viral nucleic acid testing using throat swabs becomes negative (66). Moreover, some patients will only be positive for SARS-CoV-2 virus nucleic acid in stool (6). SARS-CoV-2 in feces may be spread mainly through contact with hands or other parts after excretion. In addition, feces may dry to form small particles suspended in the air, which may be inhaled by susceptible persons. Thus, attention should be paid to preventing contact or airborne transmission of the digestive tract secretions of COVID-19 patients (8a). "
