NEW DELHI: Omicron is now at the ‘community transmission’ stage in India with hospitalisation and ICU admissions rising, though most cases of the new Covid-19 infections have been mild or asymptomatic, according to genomics consortium Insacog.

“Omicron has become dominant in multiple metros where new cases have been rising exponentially,” Insacog (Indian SARS-COV2 Genomics Sequencing Consortium), jointly initiated by the Union health ministry and the department of biotechnology along with with CSIR and ICMR, noted in its weekly bulletin dated January 10 and released this Sunday. “The threat level remains unchanged,” it added.

The health ministry has not used the term ‘community transmission’ to describe the spread of Covid-19 infections in India since 2020.


During the second wave powered by the Delta variant, the Centre had maintained the situation of Covid-19 spread was not same all over the country as there had been local outbreaks in clusters with different patterns in different areas.

According to WHO, ‘community transmission’ is a state when larger outbreaks of local transmission are experienced which can be defined through an assessment of factors including large numbers of cases which cannot be linked to transmission chains, large numbers of cases from sentinel lab surveillance or increasing positive, tests through sentinel samples (routine systematic testing of respiratory samples from established laboratories), and multiple unrelated clusters in several areas of the country or territory or area.
