Situation report 1 (21-Jan-2020) to 75 (04-Apr-2020)

China total cases as on date: 82802 (World-1051635)

China total deaths as on date: 3331 (World-56985)

China daily average new cases: 950 (World-13863) - Current values are far less than the average.

China daily average new deaths: 40 (World-756) - Current values are far less than the average.

Exponential Growth constant ‘k’ for total cases: 0.17/day (World-0.18/day) - Current values are far less than the average.

Exponential Growth constant ‘k’ for total deaths: 0.03/day (World-0.04/day) - Current values are less than the average.

The below chart has

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

21-Jan-2020) - y-axis - cumulative total death & total cases as of reported date

The below graph clearly shows that the Covid-19 spread was initially

exponential and later it started following logarithmic.

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

was controlled extensively.

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 is decaying and the current values are

less than the average.

The growth constant for deaths is decaying and

the current values are less than the average.
