Oral Zinc as an Adjunct in the Treatment of Enteric Fever: A Randomised Double-blinded Controlled Trial

Introduction: Enteric fever is an important tropical disease which takes an average of five days for defervescence even with effective antibiotic therapy. Zinc has been successfully used as an adjuvant in diarrhoeal disease. If addition of oral zinc can lead to reduction in time to defervescence, it will be a useful adjuvant in the therapy of enteric fever.
