The 'R' factor - a statistic used worldwide to track, and potentially, control the spread of the virus - is a measure of how many people are being infected by one person

New Delhi: Concern over an alarming increase in new coronavirus cases in India - 131,750 over the past 72 hours - was underlined Monday by a spike in the 'R', or 'reproduction rate', of the virus, which has jumped to 1.32 - the highest since April last year, when there were fewer than 27,000 cases.

The 'R' factor - a statistic used worldwide to track, and potentially, control the spread of the virus - is a measure of how many people are being infected by one infected person.

A 'R' of 2.0 indicates that one person with COVID-19 will, on average, infect two others. Each of those two will infect two more (spreading the disease to an average of four people) and so on.

In a pandemic situation the ideal 'R' target is below 1.0, which ensures that the virus will eventually stop spreading because it cannot infect enough people to sustain the outbreak.

In India the 'R' rate was below 1.0 for several weeks starting late November last year, which was welcome news as it forecasted a rapid decline in new Covid cases.
