Background: Typhoid is one of the medical illnesses that are contagious. S-caused infection in typhoid fever. S. and typhi. Paratyphi A is still a huge worldwide safety concern. This is difficult to treat typhoid fever scientifically because the signs frequently differ and appear close to those of other febrile diseases. Numerous studies are now possible in genetic, immunological, biochemical and microbiological settings.

Objective: To establish the relevance of widal test in the diagnosis of typhoid fever.

Method: This research was conducted at Tertiary Medical College Hospital, Dhaka from January 2016 to January 2018 to examine improvements in enteric fever clinical trends. The research has caused a minimum of 120 children aged 0 to 14 to be in typhoid fever. For all, 90 children had definite diagnosis, as shown by S isolation for typhoid or paratyphoid fever. or S typhi. Blood paratyphi and 30 were accused of harmful blood production but not typhoid fever, in scientific words. The Widal research was performed using the quick diaphragm agglutination process and was tested in accordance with the results from blood cultivation.

Results: Results showed that the accuracy of the widal tube and slide agglutination tests as used in the study in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 73%, 62%, 92% and 28%, respectively.

Conclusion: It is concluded that a large-scale test remains important as a typhoid fever diagnostics device, more flexible, cheaper and quicker than other molecular and serological studies.
