New Delhi: India's effective reproduction number (R) for Covid, an indicator of how quickly the infection is spreading, has increased to over one for the first time since January, estimates a researcher from Chennai's Institute of Mathematical Sciences. The country's R-value, steadily increasing over the last few weeks, is 1.07 for the week between April 12-18, according to Sitabhra Sinha. In the preceding April 5-11 week, it was 0.93.
The last time the R-value was above 1 was in the week between January 16-22, when the value was 1.28, Sinha said. "This increase in R-value is not just because of Delhi but also Haryana and Uttar Pradesh," the mathematician, who has been tracking the R number for India since the beginning of the pandemic, he said in an email interview.
An R-value of over 1 indicates that the number of active cases has increased. R should be contained below 1 to control the pandemic. An R number lower than 1 indicates that the disease will stop spreading as there aren't enough people being infected to sustain the outbreak.
