Analysing the Incidence of Modern-Day Typhoid Fever in Population of Urban Areas.

In developing nations, especially India, typhoid fever remains a fatal illness. Even while this disease primarily affects children, it also contributes significantly to morbidity and mortality in older populations. In India, most of the cases of typhoid fever are diagnosed clinically, or at the most by the Widal test which is not fool proof. . The illness Salmonella typhi is the bacterium that causes typhoid fever, an infectious disease that is spread orally. It is typically brought on by eating tainted food and drinking dirty water. Salmonella typhi has serological positivity for the protein flagellar antigen Hd, the polysaccharide capsular antigen, and the lipopolysaccharide antigens O9 and O12. Vi. S. typhi Compared to Vi-negative bacteria, Vi-positive strains are more virulent and contagious. Fever and malaise start to appear after the 7–14 day incubation period. Chills, headache, lethargy, anorexia, nausea, nebulous abdomen pain, dry cough, and myalgia follow the fever. Hepatomegaly, splenomegaly, painful abdomen, and Coated tongue come next.
