This study was done to investigate the prevalence of Widal positivity in a tertiary care hospital i.e., Bhaskar Medical college and teaching hospital, Moinabad, RangaReddy district, Hyderabad. In developing countries, Widal test is the only practical test available for the diagnosis of enteric fever. The Widal test is easy, inexpensive and relatively noninvasive. It can be of diagnostic value when blood cultures are not available or practical. The Widal test was done for 210 patients and it was positive in 18 cases. The present study reveals that a single Widal test is still a useful diagnostic tool in typhoid fever.
