Typhoid fever deaths

per 100,000 people, 1990–2017

Info Edit

Typhoid and paratyphoid are acute bacterial infections that most commonly cause febrile illness and gastrointestinal symptoms. Severe cases are associated with intestinal bleeding and perforation, altered mental state and, in some cases, death. We define a confirmed case as one for which there has been a positive blood culture test for either Salmonella enterica typhi or paratyphi. Diagnostic criteria do not typically accompany national surveillance reports; however, with blood culture being the standard diagnostic, we treat reported cases as confirmed. Given the poor sensitivity of blood culture, however, we estimated case definition as simply febrile illness resulting from an infection with Salmonella enterica typhi or paratyphi. This is effectively a counterfactual definition in which we attempt to estimate the number of true infections regardless of test result.
