Snippet: In the basic SIR model that captures unconstrained, free spread of the disease, the basic reproduction number R 0 is related to transmission and recovery rate by R 0 ≡ R 0,free = α/β because β −1 = T I is the average time an infected individual remains infectious before recovery or removal. Here, the time period that an infected individual remains infectious is T I,eff = (β + κ 0 + κ) −1 such that the effective, or "observed" reproduc.....
Document: In the basic SIR model that captures unconstrained, free spread of the disease, the basic reproduction number R 0 is related to transmission and recovery rate by R 0 ≡ R 0,free = α/β because β −1 = T I is the average time an infected individual remains infectious before recovery or removal. Here, the time period that an infected individual remains infectious is T I,eff = (β + κ 0 + κ) −1 such that the effective, or "observed" reproduction number R 0,eff = αT I,eff is smaller than R 0,free since both κ 0 > 0 and κ > 0.
