As coronavirus cases spiral, the 'R-value', which indicates how rapidly the virus is spreading, has crossed two in Delhi and Mumbai, researchers said on Thursday.

Chennai, Pune, Bengaluru and Kolkata have R-value (or reproduction number) of over 1, as per the data study by the researchers of the Institute of Mathematical Sciences, Chennai.

Sitabhra Sinha, who led the study, said the R-value of Delhi stood at 2.54 between December 23-29, while for Mumbai it was 2.01 between December 23-28.

Both these cities have seen an exponential rise in cases.
