**6. Limitations of the study**

This study was limited to a population of undergraduate students of a tertiary institution and the results may not be a true representation of the general population. Additionally, the serum antibody and stool antigen to *H. pylori* were detected using rapid diagnostic methods. Culture and other invasive methods such as endoscopic biopsy were not employed. Thus, the prevalence rates of *H. pylori* infection is likely to be underestimated because most commercially produced rapid diagnostic test kits have sensitivity and specificity of less than 90%.
