New Delhi: India’s effective reproduction number or R for Covid — an indicator of how fast the infection is spreading — is steady at 0.90, the same as last week. However, several states including West Bengal, Assam and Himachal Pradesh are now showing an upward trend in infections.

R indicates the average number of people who are likely to catch the infection from a Covid positive individual. The value of R should remain below 1 for the pandemic to come to an end.

Similarly, West Bengal also has R over 1. The R value for the state increased from 0.97 last week to 1.06 this week. The R value for Assam this week is 1.13, a sharp increase from last week’s 0.84.
