Virus is the pathological microbe that replicates and grows in other organisms causing diseases to the host organism. Viruses affecting bacteria are called as bacteriophages. Viruses have a great impact on immunology of human bodies, thus leading to the dreadful diseases such as AIDS and Viral hepatitis. Unlike the other microorganisms the genetic material in HIV is RNA. High-impact journals are those considered to be highly influential in their respective fields. 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. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. 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.
