Population biology of infectious diseases: Part II

Abstract
Mathematical models of directly transmitted microparasitic infections were previously developed, taking explicit account of the dynamics of the host population. The discussion is extended to microparasites (viruses, bacteria and protozoa) and macroparasites (helminths and arthropods), transmitted directly or indirectly via 1 or more intermediate hosts. Consideration is given to the relation between the ecology and evolution of the transmission processes and the overall dynamics, and to the mechanisms that can produce cyclic patterns, or multiple stable states, in the levels of infection in the host population.
