The SIR model is one of the simplest disease models we have to explain the spread of a virus through a population. I first explain where the model comes from, including the assumptions that are made and how the equations are derived, before going on to use the results of the model to answer three important questions…
Produced by Dr Tom Crawford at the University of Oxford.
Note: His honest stating of assumptions (guesses).
S = Susceptibles (a guess)
I = Infectives (another guess)
R = Removed (caught the disease. Heavily corrupted value due to NHS fraud)
Kudos for his candor unlike that liar Dr Neil Ferguson (Prof Lockdown) of UK government’s SAGE advisory group.
