This study examined the usefulness of the Widal test in Imo State, Nigeria, for typhoid disease diagnosis. In the Owerri and Orlu zones of Imo state, 2,700 test subjects-2,300 typhoid fever cases and 400 seemingly healthy individuals—were utilized to examine the incidence of typhoid fever using both the tube and slide agglutination Widal tests. The test findings were contrasted with those from routine blood culture examinations. The test subjects were divided into the following occupational groups: businessmen and women (700), students (400), farmers (450), civil servants (900), and children (250). According to the study's results, the sensitivity, specificity, positive predictive value, and negative predictive value of the Widal tube and slide agglutination tests were 54%, 77%, 90%, and 30%, respectively. A significant difference was found at p < 0.05 in the analysis of the data from the two diagnostic tools in the two zones. The Widal test is still useful as a diagnostic tool for typhoid fever in Imo State since it is more practical, affordable, and quick, according to the results.
