The opinion of a specialist doctor is must before initiation of treatment of typhoid fever. The Widal test detects anti – S. Typhi antibodies; this assay is of limited clinical utility in endemic areas like India because positive results may represent previous infection. The minimum titres defined as positive for the O antigens and H antigens must be determined for individual regions. Rapid antibody based tests including Typhidot have only moderate diagnostic accuracy and are not sufficiently accurate to replace blood culture. Treatment should be started under the supervision of a specialist, as therapy of enteric fever as become complicated by widespread antimicrobial resistance. Attention to food safety is important for prevention of enteric fever. Three vaccines are available for protection against S.Typhi.
