Correction to: Journal of Pure and Applied Microbiology, published May 9, 2020.

When revisiting the values of Beta, Gamma and R0 in our article, we the listed author(s) have found some errors and here we are pointing out some unintentionally leftover irregularities, typos and mistakes which should be corrected to justify and validate the values of Beta, Gamma and R0, as per the differential equations.

Hereby, we bring to your attention the following irregularities, typos, and mistakes in Table 2 Page 14261.

In the original paper, the equations (given below 1 to 4) and Table 2 must read as:
The rate of susceptible people is calculated for a population using Eq. (1) and the description of the parameters is provided in Table 11:


The Infection rate is calculated by Eq. (2)

The recovery rate is calculated by Eq. (3)

The death rate is calculated by Eq. (4)
