Corona second wave still prevailing in various states and rising of the reproduction number or R-Value of Covid raging dominantly in India. The Highly infectious delta variant is jumped predominance in several areas across the nation. Kerala state has a rising daily case and the R-Value started rising exponentially across the state.

What is R-Value ?
R is the number that an infected person will pass on to spread over others. The rate of coronavirus infection among the group peoples and reproduction number that it which spreads around them.

How R Value Calculated
Measuring the R-Value with current data is undoable work. Instead, scientists work on previous data of week or month like the number of people admitted, treated, cured, deceased, and positive rate of the virus, spreading over a period. R number changes as the behaviour of the human body or immunity develops.

Epidemiologists use this value to monitor the reproduction rate and the spreading nature of the virus. For instance, the value 1 denotes that every infected person, on average, is transmitting the disease to one more person. If the value shoots up above 1 the pandemic is in an increasing phase, and that cases will arise.
R-Value India

India, the US, Canada, and Australia have a 1.2 R number, on average. This is an upcoming dominant problem for its replicating nature, with an R-value of 1.1 Kerala tops the rising covid virus for the past few days. Among 44 districts in India, 10 days districts from Kerala has an alarming rate of spread. R-Value is high in 8 states such as Tamil Nadu, Himachal, Jammu and Kashmir, Mizoram, Karnataka, and more.
