    On the exact reproduction number in SIS epidemic models with vertical transmission
    (Springer, 2023-08-01) Gómez Corral, Antonio; Palacios Rodríguez, Fátima; Rodríguez Bernal, María Teresa
    This paper proposes a bi-variate competition process to describe the spread of epidemics of SIS type through both horizontal and vertical transmission. The interest is in the exact reproduction number, R_{exact,0}, which is seen to be the stochastic version of the well-known basic reproduction number. We characterize the probability distribution function of R_{exact,0} by decomposing this number into two random contributions allowing us to distinguish between infectious person-to-person contacts and infections of newborns with infective parents. Numerical examples are presented to illustrate our analytical results.
