New Delhi: The effective reproduction number or R for Covid — an indicator for how fast the infection is spreading — remained steady in India this week at 0.94, although several states like Karnataka saw values jump over 1.

R indicates the average number of people who are likely to catch the infection from one sick person. R should remain below 1 for the pandemic to come to an end.
