Karnataka among 8 states with high Covid R-value
With an R-value of 1.2, Karnataka is among the eight states and UTs in the country the R-value has risen above 1, the Union Ministry of Health and Family Welfare has noted.
R-value estimates the number of people that an infected person is transmitting the disease to, on an average. A value of 1 means every infected person, on an average, is transmitting the disease to one more person. A value greater than 1, therefore, means the pandemic is in an ascendant phase, and that cases will rise.
The Centre said the fact that the R-value rising beyond 1 is “truly a cause of concern”, and indicated the possibility of a further rise in cases in the coming days.
