1.1 BACKGROUND OF THE STUDY

Typhoid Fever is a world wide disease which creates a very serious public healthy problem. In many under develop countries; the word health organization (WHO) estimated that about one person out of ever hundred (100) is suffering from typhoid fever. The also identify typhoid as a serious public health problem which incidence is highest in children and young adults between 5-19 years old.

Typhoid fever is a systematic disease caused by dissemination of salmonella typhoid or salmonella paratyphoid mainly characterized by fever was called because of it’s common similarity to typhus. It was clearly defined pathologically as a unique disease of it’s own, it is a common world wide illness, transmitted by the ingestion of food or water contaminated with the faces of an infected person, which contain the bacterium salmonella enterica. The bacteria then perforate through the intestinal wall and are phagocytosed by macrophages.

The average incubation period is 10-14 days. A progressive fedric illness marks the onset of disease which develops as the germ invades tymphoid tissues, including that of the small intestine (peyers patches) to profuse diarrhocal (pea soup) stools which may become frankly haemorrhagic, ultimate recovery usually begins at the end of the third week. A rose coloured rash may appear on the upper abdomen and back at the end of the first week.
