Clinical presentation and comorbidities of invasive Salmonella disease and mortality in Malawian children.

(A) Area-proportionate Venn diagram indicating the different presenting clinical syndromes of pediatric invasive Salmonella disease. Gastroenteritis is defined as children with a history of diarrhea or vomiting, and a respiratory presentation as the presence of cough, shortness of breath or respiratory distress. (B) Area-proportionate Venn diagram indicating comorbidities (HIV, malaria and severe malnutrition) of children presenting with invasive Salmonella disease. Figures are absolute numbers (percentages in brackets) of children in each group, with mortality in each group given below and are shown for individual variables and for children in whom these overlapped. Discrepancies between totals in the figures and the text are due to children with missing data for one of the categories depicted.
