Recent wastewater-based epidemiological studies from several countries also detected SARS-CoV-2 RNA in raw wastewaters. SARS-CoV-2 can survive and remain viable for up to 6 to 9 days on surfaces. Evidence shows that SARS-CoV-2 proliferate in the human gastrointestinal system, and is shed via faeces.
The current perspective examines the latest evidence on the occurrence, persistence and faecal-oral transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the etiological agent causing COVID-19. In developing countries, the need for clean water provision, sanitation and hygiene has only received limited attention. Social distancing, hand hygiene and the use of personal protective equipment dominate the current fight against COVID-19. The human coronavirus disease (COVID-19) is now a global pandemic.
