The resulting process allows us to deal with non-exponential distributional assumptions on the contact process between the compartment of infectives and the compartment of susceptible individuals, and the recovery process of infected individuals, but keeping the dimensionality of the underlying Markov chain model tractable. The variability between SIR-models with distinct level of correlation is discussed in terms of extinction times, the final size of the epidemic, and the basic reproduction number, which is defined here as a random variable rather than an expected value.engjournal articlehttp://www.doi.org/10.3934/dcdsb.2018229http://aimsciences.org/journal/1531-3492restricted accessProbabilidades (Estadística)1208 Probabilidad
