BACKGROUND OF HOSPITAL AQUIRED INFECCTIONNosocomial infections have been recognized for over a century as a critical problem affecting the quality of health care and a principal source of adverse healthcare outcomes.

Nosocomial infection comes from Greek words nosus meaning disease and komeion meaning to take care of.

It is also called : HOSPITAL AQUIRED INFECTION

DEFINITION OF NOSOCOMIAL INFECTION: An infection acquired in a patient in a hospital or other healthcare facility in whom it was not present or incubating at the time of admission or the residual of an infection acquired during a previous admission.

EPIDEMOLOGY Nosocomial infections can be exogenous (external organism) and endogenous (opportunist normal flora).

Host susceptibility Is an important factor in the development of nosocomial infection.

Medical equipments and procedures (surgery) are often responsible for infections.CAUSATIVE AGENTS OF NOSOCOMIAL INFECTION

Different pathogens may cause nosocomialInfections:MODES OF TRANSMISSION:

1- CONTACT TRANSMISSION:

Most important and frequent mode of transmission of nosocomial infections, is divided into two subgroups :

Direct-contact transmissionIndirect-contact transmission.Direct-contact transmission:Involves a direct body surface-to-body surface contact and physical transfer of microorganisms between a susceptible host and an infected or colonized person, such as occurs when a person turns a patient, gives a patient a bath.Indirect-contact transmission:Involves contact of a susceptible host with a contaminated intermediate object, usually inanimate, such as contaminated instruments, needles , or dressings, or contaminated gloves that are not changed between patients

2-DROPLET TRANSMISSION:Droplet generated by sneezing coughing or respiratory tract procedures like bronchoscopy or suction.

3-VECTOR TRANSMISSION:Transmitted through insects and other invertebrates animals such as mosquitoes and fleas.

4-AIR BORNE TRANSMISSION:Tiny droplet nuclei that remain (
