WebApr 25, 2024 · The SIR model is too simple for any realistic computation in a situation where 90% of the assumed infected are undetected or asymptomatic. 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. 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.
