Is the virus causing COVID-19 found in sewage viable?

The fragments of genetic material (RNA) detected from sewage are very quickly decomposed in sewage water and will only be stable if protected by the protein coat (capsid), meaning only if the whole virus is present. Therefore, demonstrating these specific RNA fragments in sewage wastewater implies that whole virus particles were present. We currently know too little about the possible infectious activity of coronavirus (SARS-CoV-2) particles in sewage water, but from the information that we have this far it does not seem very likely that coronavirus particles in wastewater can infect people.
