|A simultaneous infection with one or more diseases is called a co-infection. Mostly HIV-positive patients are co-infected with Hepatitis such as Hepatitis C virus (HCV) and Hepatitis B virus (HBV), due to shared routes of transmission. HCV is most commonly infected than HBV. Hepatitis virus rapidly effects in HIV positive patients compared to HIV negative patients. HIV Co-infection with hepatitis put patients at higher risk of life-threatening health complications and also makes the management of HIV infection more difficult.
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.
