What can we speculate from literature about the presence of SARS-CoV-2 in feces, and contamination through the faecal-oral route and aerosols?

Sewage water has not yet been described as a transmission route and the risk is estimated to be very low. The virus concentrations in sewage water and aerosols generated from sewage water are probably much lower than what an infected patient exhales. Examples from previous work: 1. residents near wastewater treatment plants (WWTP) have been investigated on infections by water-transmissible viruses. This did not reveal that waterborne viral diseases were occurring more frequently. 2. The strict quarantine in Asian cities has worked, while sewage and purification have not been “quarantined”. So hence no indication that WWTPs or aerosols play a role.
