The aim of the paper is to study some continuous characteristics of the epidemic. In this sense, we first extend the classical study of the length of an outbreak by investigating the whole probability distribution of the extinction time via Laplace transforms. Moreover, we also study two almost new epidemic descriptors, namely, the time until a non-infected individual becomes infected and the time until the individual is removed from the infective group. The obtained results are illustrated by numerical examples including an application to a stochastic SIS model for head lice infections.engjournal articlehttp://www.tandfonline.com/doi/abs/10.1080/17513758.2011.552737http://www.tandfonline.com/open access519.2extinction timehead licerecovery timestochastic SIS modelstochastic SIR modeltime to infectionEstadística matemática (Matemáticas)Procesos estocásticos1209 Estadística1208.08 Procesos Estocásticos
