I am doing a project on modelling the spread of diseases and am using a SIR (susceptible, infected and recovered) model to do so. I need help interpreting this plot:
What does this plot say about an epidemic of a population?
any help is appreciated thank you
Basically what it says is the at the worse time, around 10% of the populations will be infected. More importantly, the asymptotic solution shows that "only" 60% of people will be affected which implies that 40% of the population will never get sick.
All plots show the proportion of your population divided into three classes at any time $t>0$.
Finally, you can see that after approximately 3 days (assuming $t$ is in days), your infection has already almost disappeared as it is not able to transfer to anyone else.
If there's any aspect I didn't cover and you want more explanation about, feel free to comment.
