Virus is the pathogenic microbe that causes infections in human body. Virions are the virus particles which are consisted of two parts such as genetic material and protein coat. Viruses mainly affect the human immune system of the human body. Hepatitis virus is the common virus that degenerates the immunity of the body. Virulence is the capacity of the virus to infect the human system. Vaccination helps in preventing the infections caused by virus, as it produces the antibodies that are necessary in defense mechanism. The most common and well know lethal disease caused by human immune deficiency virus is AIDS. 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.
