INSACOG TO TRACK SARS-CoV-2 IN SEWAGE

Context

The decline in daily new infections across India has prompted INSACOG (India SARS-CoV-2 Genome Consortium), the consortium of labs focused on sequencing coronavirus variants, to “prioritise” new surveillance approaches.

About

In view of currently declining cases and importance of early detection of increased transmission in the future, INSACOG will prioritize developing and expanding a SARS-CoV-2 sewage surveillance program.
The CSIR-Centre for Cellular and Molecular Biology, which is also part of the INSACOG network, has since early 2020 been collecting sewage from large drains in cities to check for the presence of the virus.
Because a large fraction of those afflicted by the virus are asymptomatic but are carriers of infection, their body fluids and stool often contain traces of the virus.
Finding large proportions of it in public drains can often be a precursor to a fresh outbreak, with a rise in symptomatic infections.
Delta (B.1.617.2 and AY.x) continues to be the main VOC (Variant of Concern) in India. No new VOI (Variant of Interest) or VOC are noted in India.

INSACOG

INSACOG (Indian SARS-CoV-2 Consortium on Genomics or Indian SARS-CoV-2 Genetics Consortium is the forum set up under the Ministry of Health and Family Welfare by the Government of India on 25 December 2020, to study and monitor genome sequencing and virus variation of circulating strains of COVID-19 in India.
INSACOG works as a consortium of 28 national laboratories for genome sequencing located in different parts of India.
