A host is an organism that the parasite lives on. In other words the parasite may use the host's resources in a negative way.
For example: A tick living off the blood of a human. The tick is the parasite and the human is the host. The tick lives off the blood of the human.
Pathogens comprise both animate and non animate objects, their presence on the body of the living tissues of either plants or animals lead to production of symptoms typical of a disease. Parasites on the other hand, are living (Bacteria, Protozoa, etc) and semi-living (viruses) entities that live inside the host securing shelter and nourishment from its host body and either causes damage to the host (e.g Plasmodium vivax causes malaria to man) or give something (E. coli in man's intestine) in return.
