Study finds Covid gene in wastewater, paves the way for using wastewater-based epidemiology for real-time surveillance

In a major breakthrough that paves the way for using wastewater-based epidemiology (WBE) for real-time surveillance of COVID-19 in the country, a study, led by scientists in IIT-Gandhinagar, found that increased gene copies of the virus in Ahmedabad’s wastewater matched the incidence of the disease in the city. It is believed that WBE is a promising approach to understand the status of disease outbreak in an area as treatment plants collect wastewater across large regions and measuring the level of RNA in untreated wastewater may provide a valuable insight into the percentage of people infected within a region.
