Manish Kumar, professor and head of research at the Department of Earth Sciences at IIT Gandhinagar, told PTI-Bhasha, “This is the first evidence based on weekly monitoring in India that the monitoring of wastewater has led to Kovid-19’s earlier It can be warned. “He said,” The result is very encouraging and we are planning to share it with the authorities. “
Need to stop kovid all over the worldProfessor Kumar said that it is the need of the hour that the officials should also include waste water monitoring in the policy to deal with the Kovid-19 epidemic.
Professor Prasoon Bhattacharya of the Sweden-based KTH Royal Institute of Technology also agrees that wastewater monitoring should be included not only in India but across the world as a measure to curb the Kovid-19 epidemic.
It is noteworthy that this study was done in partnership with Gujarat Pollution Control Board (GPCB) and the study is under review by the journal Environmental Research. The research is based on a study conducted in Ahmedabad in May last year, under which the research team successfully detected the corona virus in wastewater for the first time in India.
In the latest study, the research team analyzed SARS-COV-2 RNA (genetic material) in 43 samples taken from four wastewater treatment units from August 7 to September 30 last year. During the study, samples were collected twice a week and this process lasted for two months.
The study found 40 samples out of 43 infected.
According to the researchers, three genes of SARS-COV-2 were considered and samples were considered positive in the presence of two or all of them.
During the study, 40 samples out of total 43 samples were found infected. Subsequently, a comparative study of these samples and the official data of infection was done and it was seen how much change in the condensation of virus fraction in the wastewater samples.
“We found SARS-COV-2 genes in wastewater first, followed by infection symptoms in patients,” said Errol Bivins of the University of Notredum.
Researchers said that by examining the samples collected from wastewater treatment units of large area and the level of RNA in them, one can find the level of infection among people in the area.
