WebNov 18, 2024 · The SIR model is ideal for general education in epidemiology because it has only the most essential features, but it is not suited to modeling COVID-19. The SEIR model is the logical starting point for any serious COVID-19 model, although it lacks some very important features present in COVID-19. WebMay 24, 2024 · The SIR model. The SIR model is an epidemic model that shows the change of infection rate over time. More speci cally, it characterizes the dynamic interplay among the susceptible individuals (S), infectious individuals (I) and removed individuals (R) (including recovered and deceased) in

Also, the COVID tests do not detect or prove viral infection, only some tracer RNA (and not the same of that for all tests) by some unreliable lab method, so the data is tainted.

If T I is the Exponential distribution then we have the general epidemic = Markov SIR epidemic. For non-Exponential T I then {(S(t),I(t)): t ≥ 0} is not a Markov process.
