A parasite is a living organism, which takes its nourishment and other needs from a host; the host is an organism which supports the parasite. Parasites can also exploit alterations in host reproductive behavior to further increase parasite fitness. Many alterations of host behavior benefit the parasite, and seem to constitute a parasite strategy for increased survival and reproduction. However, there are systems in which the host alters reproductive efforts in response to parasites, perhaps attempting to mitigate the damaging effects eventually induced by infection. Such struggles between host and parasite for host energetic resources drive the dynamics of host and parasite. The scoping review looks at the main classes of parasites that can cause disease in humans such as: protozoa, helminths, and arthropods. It goes further to look at the transmission styles such as water borne, food borne and vector borne parasitism. The knowledge of the parasites, reproduction and control measures are explored for good understanding of public health and medical students.
