Comparison of the intrinsic growth rate of infectious diseases. (A) For a given R0 and the mean generation time Tg for a given infectious disease, the curves show the relationship between the intrinsic growth rate (r) and the coefficient of variation of the generation time of the disease. r of measles is the largest, followed by influenza, and then Ebola virus disease (EVD). (B) Temporal evolution in the number of new cases of measles, influenza, and Ebola virus disease using a coefficient of variation of the generation time at 50%. Parameter values are given in Table 1.
