New Delhi: India’s effective reproduction number (R) for Covid-19, which indicates how fast the infection is spreading, has increased from 1.18 to 1.30 in the last two weeks.

This is the highest the value has been since April last year when India was under total lockdown, according to Sitabhra Sinha, a researcher at the Institute of Mathematical Sciences in Chennai, who has been tracking R since the beginning of the pandemic.

All 16 states that have the highest share of active cases in the country have R above 1, Sinha told ThePrint.

For a pandemic to come to an end, the R value has to be sustained under 1.

At present, Uttar Pradesh has recorded the highest infection value at 1.62, an increase from 1.10 in the last two weeks. This is followed by Andhra Pradesh whose R increased from 1.31 to 1.61 this week.

Chhattisgarh’s R stands at 1.57, which increased from 1.44 in the last two weeks. The state has the third-highest active cases in India and recently entered the rank.

Delhi is currently witnessing its fourth wave of Covid infections and its R increased to 1.47 this week. Two weeks ago, the value was 1.23.

Rajasthan also has a high infection rate at 1.46 from 1.24, two weeks ago.
