RT Journal Article T1 On the Number of Periodic Inspections During Outbreaks of Discrete-Time Stochastic SIS Epidemic Models A1 Gamboa Pérez, María A1 López Herrero, María Jesús AB This paper deals with an infective process of type SIS, taking place in a closed population of moderate size that is inspected periodically. Our aim is to study the number of inspections that find the epidemic process still in progress. As the underlying mathematical model involves a discrete time Markov chain (DTMC) with a single absorbing state, the number of inspections in an outbreak is a first-passage time into this absorbing state. Cumulative probabilities are numerically determined from a recursive algorithm and expected values came from explicit expressions.
