New Delhi: India’s effective reproduction number or R for Covid — an indicator of how fast the infection is spreading — continues to remain steady at 0.94.

R represents the average number of people who are likely to catch the disease from one infected person. The R value should remain below 1 for the epidemic to come to an end.

Over the last several weeks the R for India has stayed the same at 0.94, although several states and metros have been showing fluctuations.
