Place and Duration of Study: Department of Medical Laboratory Science, Babcock University, Ilishan-Remo, Ogun State, Nigeria, between April and June, 2018.
Materials and Methods: Blood and stool specimens were randomly collected from 200 consenting undergraduate Students and screened using Solid Rapid Diagnostic Typhoid (United Kingdom) and Accu-Chek S. typhi antigen (India) Test Kits, respectively according to the manufacturer instruction.
