The study of parasites is called as parasitology. Parasites are microbial organisms that survives on host. Some of the parasitic diseases such as malaria may lead to lethal conditions. Parasitic organism such as protozoa feed on other microbes for their survival. Warm climatic condition favours for the parasites to cause infection or disease. African countries are more prone to malaria kind of infections. The worm parasites that cause human diseases are tape worms, pin worms and round worms. Filariasis is another kind of parasitic diseases transmitted from one person to other through insects, wherein the leg swells and resembles an elephant leg. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
