Chronic and Communicable Diseases - Research Paper ExampleDiseases process problems to the corpse of a human being, as well as other animals. They affect the body processes from taking place in the normal way. From the infectious diseases perspective, vectors atomic number 18 the agents that transmit organisms that cause diseases (Beaty, 1996). These organisms are responsible for carrying pathogens to different hosts, as they feed or move from one animal to the other. Vectors fall under the category of namby-pamby animals and this category of animals comprise the arthropods (Gubler, 1997).It is imperative to note that vertebrates can also act as vectors, which can transmit diseases as invertebrates. For instance, skunks, raccoons and foxes are among the vectors that transmit diseases, despite the item that they are vertebrates. They can transmit the virus that causes rabies in human beings through a bite. Although the arthropods constitute the largest percentage of the unknown sp ecies of animals, they are the most operative disease vectors (Beaty, 1996). Vectors can have a direct or indirect effect on human health. The direct effect of vectors on human health results from tissue infestations, stings and bites from the vectors. On the other hand, the indirect effect results from transmission of organisms causing diseases.The most distinguished vectors of disease are the ticks and mosquitoes, but there are several(a) genera of arthropods, which play a function in the disease of human (Lemon, 2008). Further, the most crucial mode that vectors utilize to transmit the vector-borne diseases is the biological transmission which entails the blood-feeding arthropods. The pathogen reproduces while it lives at heart the vector arthropod, and the pathogen is passed to the host as the vector feeds on blood from the host (Gubler, 1997). Furthermore, vectors can transmit diseases through mechanical transmission they carry the disease-causing organisms on their body
