He said stringent curbs have been put in place as part of the Graded Response Action Plan for COVID-19 to check the spread of the infection and the Delhi Disaster Management Authority (DDMA) will decide on implementing more restrictions.

"There are 200 coronavirus patients in Delhi hospitals. Genome sequencing of the samples of 115 patients showed 46 per cent had Omicron. These people include those who do not have any travel history. It means Omicron is now inside Delhi," Jain said.

"Indeed, the variant is gradually spreading in the community," the minister said.

He also said of the 200 coronavirus cases in Delhi hospitals, only 102 belong to the city.

The Delhi Disaster Management Authority (DDMA) sounded the "yellow" alert under its Graded Response Action Plan (GRAP) on Tuesday, after the Covid positivity rate was recorded above 0.

5 per cent in the national capital for two consecutive days.

It ordered a closure of schools, colleges, cinema halls and gymnasiums with immediate effect and clamped various restrictions on the functioning of shops and public transport.

A "yellow" (level-1) alert is sounded when the Covid positivity rate is recorded above 0.

About 38 per cent of the total samples analysed at various genome sequencing laboratories in Delhi in the past one week have been detected with Omicron variant of Covid, according to officials documents, as the cases of the new variant saw a record spike in this period in the national capital.
