Abstract

The most important advances in science related to infectious agent transmission in multi-host systems over the past ten years. Nearly 60% of the diseases that have appeared in humans during the past 30-40 years are of animal origin, and 60% of them have a significant range of hosts outside of humans. We concentrate on zoonotic illnesses with vector-borne transmission and analyse the divergent influences that a variety of host reservoirs and vectors may have on their disease dynamics. Three or more potential host species. We explore the reduction, including the dilution impact, or amplification of pathogen prevalence caused by the richness and mix of host and vector species. In this work, we will use the term “parasite” to refer to carriers of infectious diseases because the majority of significant infections and parasites that influence human populations are zoonotic.
