A human or animal with an infection has another organism inside them which gets its sustenance (nourishment) from that person, it colonizes that person and reproduces inside them. The human with that organism (germ) inside is called the host, while the germ or pathogen is referred to as a parasitic organism. Another name for an organism that causes infection is an infectious agent. It is only an infection if the colonization harms the host i.e parasitic relationship. It feeds and multiply at the expense of the host to such an extent that the host’s health is affected adversely. The normal growth of the bacterial flora in the intestine is not an infection, because the bacteria are not harming the host.
In the light of the above this work shall enable us understand how parasitic infection causative agents like malarial parasite species and their vectors respond sharply to changes in the ecology of their habitat: deforestation, vegetation, density of human population, bodies of water and their locations and climate Africa and the world at large.
It will be good to indicate that this work is divided into 3 chapters with which the topic under study was exhausted. Chapter 1 was used to explain all basic terms, at chapters 2 and 3 the topic of research was dealt with in detail as the main body of the work.
The work also contained conclusion and references.
