Hospital acquired infections (HAIs) or nosocominal infections refer to the infections that are developed and affect patients during their hospitalization. HAIs control focuses on preventing, sterilization, cleaning, testing and treating infections occurring in the hospital’s environment. HAIs control is an important step in hospital management. This is due to the fact that hospitalized patients have weak immune system and they can easily get infected by any of the microbes such as bacteria, virus and fungus and other less common type of pathogens causing HAIs. Also, use of non-sterilized injection equipment and other medical devices, contaminated air, water, food and medicines, reuse of disposable equipments, dirty wards and no proper biomedical waste management causes infections to patients and healthcare workers in the hospital. Nosocominal infections are also one of the leading causes of death among hospitalized patients. Some of the most common types of infections are bloodstream infection (BSI), pneumonia, surgical site infection (SSI), lower respiratory infections, gastrointestinal tract, central nervous system, traumatic wounds and burn infections, primary bacteremia and urinary tract infection (UTI). Burn units, emergency departments and intensive care units are the major infection risk areas in the hospitals. Understaffing and low levels of staff attentiveness and knowledge are some of the key factors that lead to poor infection control.
