Main plots
Corona virus spread is characterized by three values:
- Total confirmed cases.
- Recovered people.
- Deaths.
Worldwide plots | Europe plots |
---|---|
Plots are in log scale, starting from 1 February to 15 March 2020.
Animation to better understand geography paths of virus:
Worldwide | Europe |
---|---|
ps: absolute scale of bubble is changing with time only relative sizes makes sense.
Derivatives
To understand better dynamics of these curves let simply evaluate derivatives. First - which intuitivelly can be understood as speed, and second - as acceleration:
When I first evaluate these plots I was amazed!
Second derivatives are negative it means that speed is slowing down, and if You take a look on Europe plot - it is sloving down exponentially like! So spreading overally in Europe is starting to slowing down.
And now we can extrapolate Confirmed Cases curve using logistic function.
UPD: Forgot "-" minus sign at evaluation of second derivative... It is exponential like and positive. Situation is still serious.
Correct derivative plots:
Worldwide | Europe |
---|---|
