A Nosocomial infection is contracted because of an infection or toxin that exist in a certain location such as a hospital.
People now use Nosocomial infection interchangeably with the terms Health- Care Associated Infection (HAIS) and Hospital Acquired Infection. For a HAI, the infection must not be present before someone has been under medical care.
One of the most common wards where HAIS occur is the Intensive Care Unit (ICU) where doctors treat serious diseases. Rutala, (2010).
About 1 in 10 of the patient admitted in a hospital will contract a HAI. They are also associated with significant morbidity, mortality and hospital costs.
As medical care becomes more complex and antibiotic resistance increases the cases of HAIS will grow. The good news is that HAIS can be prevented in a lot of health care situations. Hassan, (2017).
A Nosocomial infection is specifically prior to the patients being admitted to the hospital, but can occur within 72 hours after admission to the hospital.
