Hospital Acquired InfectionsHave you ever wondered if visiting a hospital can cause you to pick up various infections? In case your answer is no, then you should be aware of the existence of something called a hospital acquired infection. Also known as a nosocomial infection, this is a common occurrence in a large number of patients around the world.

Hospital acquired infections are defined as infections that affect the patient within 2 days of hospital admission or 3 days after discharge. This type of infection is also commonly observed after surgery, which usually occurs within a month of an operation.
