The first proof of the capability of wastewater surveillance for COVID-19 in India through the detection of the genetic material of SARS-CoV-2
2020
we made the first-ever successful effort from India to detect the genetic material of SARS-CoV-2 viruses to understand the capability and application of WBE surveillance in India. Sampling was carried out on 8 and 27 May 2020 from Old Pirana Waste Water Treatment Plant (WWTP) at Ahmedabad, Gujarat with 106 million liters per day (MLD) capacity receiving effluent of Civil Hospital treating COVID-19 patient. All three i.e. ORF1ab, N and S genes of SARS-CoV-2 were discerned in the influents with no gene spotted in the effluent collected on 8 and 27 May 2020. Temporal difference between 8 and 27 May 2020 samples was of 10x in gene copy loading with a corresponding change of 2x in the number active COVID-19 patient in the city. Number of gene copies was found comparable to that reported in the untreated wastewaters of Australia, China, and Turkey and lower than that of the USA, France, and Spain. This study, being the first from India and probably among the first ten reports in the world of gene detection of SARS-CoV-2 in the environmental samples, aims to assist concerned authorities and policymakers to formulate and/or upgrade the COVID-19 surveillance to have an explicit picture of the phase of the pandemic. While infectious SARS-CoV-2 has yet to be identified in the aquatic environment, the virus potentially enters the wastewater stream from patient excretions and thus can be a great tool for pandemic monitoring.
