The below chart has

- x-axis - Report number (OR) Day number (Report number 1 starts on

21-Jan-2020) - y-axis - Cumulative total deaths & total cases as on reported date

The below graph clearly shows that the Covid-19 spread is exponential.

The below chart has

- x-axis - Report number (OR) Day number (Report number 1 starts on

21-Jan-2020) - y-axis - Daily reported new deaths & cases

The below graph clearly shows that the Covid-19 daily new spread

is exponential.

The below chart has

- x-axis - Report number (OR) Day number (Report number 1 starts on

21-Jan-2020) - y-axis - Growth constant (K) for cases / deaths

Growth constant is calculated from the below general growth/decaying

formula

A=Pe^{kt}

The growth constant for cases was decaying and stabilizing to a value

around 0.11.

The growth constant for deaths was floating around a constant value and

started increasing slowly.
