In December 2019, new outbreaks of Severe Acute Respiratory Syndrome Coronavirus 2 (nSARS-CoV-2) virus emerged in Wuhan, China, and spread around the world, including India. Molecular diagnosis of coronavirus disease 2019 (COVID) 19 for a densely populated country like India takes time. Few reports have described the successful diagnosis of nSARS-CoV-2 virus from sewage and sewage samples contaminated with fecal matter, suggesting the diagnosis of COVID 19 from it to alert transmission virus community for the implementation of evacuation and lockdown strategies. So far, the association between detection of the virus and its concentration in stool samples with the severity of the disease and the presence or absence of gastrointestinal symptoms has been rarely reported. We conducted the research using several databases, in particular PubMed (Medline), EMBASE and Google Scholar. We studied the literature on gastrointestinal infection and the spread of this virus by faecal-oral transmission. Reports suggest that the existence and persistence of nSARS-CoV-2 in anal / rectal swabs and stool samples for a longer period than in nasopharyngeal swabs provide a strong and tenable result of gastrointestinal contamination and of the spread of this infection via potential faecal-oral transmission. This review may be useful for conducting further studies to address enteric involvement and excretion of nSARS-CoV-2 RNA in faeces and to monitor community spread in COVID-19 patients before symptoms appear. and in asymptomatic individuals via wastewater and wastewater. surveillance as an early indication of infection. The existence of the viral genome and of the active viral particle actively participate in genomic variations. Therefore, we understood the enteric spread of different viruses among communities with special reference to nSARS-CoV-2. This article is protected by copyright. All rights reserved.
