No cases of transmission through food have been found for the new coronavirus pneumonia, but positive nucleic acids have been found in the feces and urine of infected persons, and it has not yet been confirmed that the nucleic acids in the feces are intact viruses or fragments of viruses. Through the understanding of SARS, there is indeed a possibility of transmission through feces. There have been cases of hundreds of infections in the same community after the diarrhea of SARS patients, and it is speculated that feces may have contaminated the ventilation system or water supply, leading to infection of a large number of people in the community. So the possibility that if the water source is contaminated, people who then drink the water become infected cannot be ruled out. The only cases of novel coronavirus pneumonia that have been found to be nucleic acid positive in feces are those in which the infection has not yet been found to have been contracted because someone drank water or ate something. Therefore, it is important to be aware of the potential transmission of excreta and feces. Public health authorities are reminded to manage water sources properly to avoid contamination. If the water source is contaminated, the potential for infection in the digestive tract could lead to hundreds, thousands, or even larger outbreaks, so it is important to be prepared for this.
