New Delhi, April 23: Delhi’s R-value that indicates the spread of Covid-19 was recorded at 2.1 this week, which means every infected person is infecting two others in the national capital. The analysis has been done by IIT-Madras.
The 'R' or reproductive value indicates the number of people a Covid-19 infected person can spread the disease to, and a pandemic is considered to end if this value goes below one. The preliminary analysis by computational modelling was done by IIT-Madras' Department of Mathematics and Centre of Excellence for Computational Mathematics and Data Science headed by Prof Neelesh S Upadhye and Prof S Sundar.

Delhi's R-value this week was recorded at 2.1. India's R-value, at present, stands at 1.3, the analysis found.
For other metro cities like Mumbai, Chennai and Kolkata, the number of cases is too low to ascertain a trend. Delhi is witnessing a surge in the number of Covid-19 cases. The city logged 1,042 fresh Covid cases with a positivity rate of 4.64 per cent on Friday.
The Omicron sub-lineage BA.2.12 has been detected in a majority of the samples sequenced from Delhi in the first fortnight of April and it could be behind the recent surge in Covid cases in the city, sources said on Thursday.
However, an Indian SARS-CoV-2 Genomics Consortium (INSACOG) source has claimed that Omicron variant derivative BA.2.12.1 has also been found in a few samples in Delhi which is said to be contributing to the recent rise in cases in the US.
