India’s R-value, or the rate at which the coronavirus pandemic is spreading has remained below 1 since September indicating that the infection rate is dropping, said a study conducted by the Chennai Mathematical Institute (CMI). The R-value signifies how many people one person can infect on an average and can reflect the potency of the virus.
If the R-value is lesser than one then the virus is spreading at a slow rate, while if it is higher than one then the number of infected people is increasing in each round and this happens when the epidemic is at its height.
Based on their calculations, the CMI researchers found that the R-value of the top ten states with the most number of active cases was below 1 until October 18, said media reports.
However, some cities continued to show a rising number of active cases. Kolkata, for example, has an R-value over 1, probably due to the massive crowds during the Durga Puja, said Sitabhra Sinha, who is leading this research, said a News18 report. Bengaluru too shares this dubious distinction of having an R-value over 1 since mid-September. The R-values of Chennai, Pune and Mumbai are however just below 1.

India’s R-value, which was calculated for the period between September 25 and October 18, was 0.90. But between August 30 and September 3, the value had hit 1.11 and subsequently dropped hovering at 0.94 between September 4 and 7. It was 0.86 between September 11 and 15, 0.92 between September 14 and 19 and 0.87 between September 17 and 21, according to the study.
After the severe second wave of coronavirus raged in the country between March to May this year, the daily COVID-19 cases have started to go down. On Tuesday (October 19), India reported 13,058 new coronavirus infections, which is the lowest in 231 days, according to the Union Health Ministry’s data, said media reports.
The country logged below 30,000 new coronavirus infections for 25 straight days and less than 50,000 daily new cases were recorded for 114 consecutive days now.
The active cases comprise 0.54 per cent of the total infections, the lowest since March 2020, while the national COVID-19 recovery rate was recorded at 98.14 per cent, the highest since March 2020, the ministry said.
