|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. A co-infection with tuberculosis is also one of the leading causes of death among people living with HIV. Latent TB infection will increase rapidly in the HIV positive patients as the HIV virus weakens the human immune system.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
