The R0 factor also known as Basic Reproduction Number. The R0 factor of an area denotes how many more persons can be infected due to a person who is having the disease. If R0 is 1.2 then it means 1 infected person can infect 1.2person by the same disease. So that 5 people can infect total 6 new persons (1.2*5=6.0).

Table 9 It is shows the believed that India is having steady R0=1.23 since 25th May which is still higher than normal. While imposing nation-wide lockdown R0 is considered as one of the factor. If the R0 values are less than 1 i.e. one infected person cannot infect another person then lockdown is to be lifted. But Lockdown in India is being lifted in steps despite having R0 factor greater than It could lead to drastic results in future
