    The reliance on multiple hosts to survive is what makes the management and control of multi-host infectious agents challenging. Sarcoptes scabiei causes sarcoptic mange in a wide range of mammal species with ungulates being an important host. Little is known about the role different ungulates play in sustaining endemic transmission of the disease and no study has yet to describe the long-term multi-host sarcoptic infestation dynamics in free-ranging wildlife. Here, we explore 24 years of sarcoptic mange infestation data for two Mediterranean ungulate species, red deer and Iberian ibex, living in the Sierras de Cazorla, Segura y Las Villas Natural Park of southern Spain. The temporal analysis showed a clear seasonal pattern of infestation in both ungulates with a peak in early spring and a decline throughout the summer. The spatial analysis, however, showed that caprinae rather than cervidae is the most competent host for sarcoptic mange spreading and persistence. Considering that few studies have described the spatio-temporal pattern of mange outbreaks for long periods of time, the information reported in this work aims to improve our understanding of sarcoptic mange epizootic in wild ruminant populations.
