A human or other living animal, including arthropods, affording under natural conditions subsistence or lodgement to an infectious agent. Some protozoa and helminths pass through successive stages in alternate hosts of different species. Hosts in which the parasite attains maturity or passes its sexual stage are primary or definitive hosts; those in which the parasite is in a larval or asexual state are secondary or intermediate hosts Host preference The preference of a mosquito (or other parasite or micropredator) for a particular type of host, human or animal. (To be distinguished from simple readiness to feed on a given type of host when no other is available).
