Abstract: Typhoid fever is a bacterial infection that spread through contaminated food or water, affecting many organs in human body; it has raised a very serious health threat in some developing nation, especially in Nigeria. This work is based on the statistical study of typhoid fever patients admitted at Bishop Shanahan hospital for a period of five years from January 2012 through December 2016. The data for the study was collected from in-patients record files of the above mentioned hospital. The data was presented according to duration of stay of patients in the hospital, gender of the patients, type of typhoid fever each patient suffers from and age of the patients respectively. It was also observed from the figure that age brackets of 19-36 are prone to typhoid fever than other brackets but people who are 73 years of age and above stay longer in the hospital as a result of weak immunity due to old age. Chi-square test of independency was used to analyze the data and it was found that duration of stay of typhoid fever patients is independent of gender of the patient but is dependent on type of typhoid fever patient suffers from, age and the doctor that attended to the patients.Abstract: Typhoid fever is a bacterial infection that spread through contaminated food or water, affecting many organs in human body; it has raised a very serious health threat in some developing nation, especially in Nigeria.
