A. log anti-Vi IgG concentration amongst participants with persistent fever, comparing titres at 3 months (lilac) and 6 months (turquoise) post-outbreak. B. log anti-Vi IgG concentration amongst participants without persistent fever, comparing titres at 3 months (lilac) and 6 months (turquoise) post-outbreak. C. log anti-H:d IgM concentration amongst participants with persistent fever, comparing titres at 3 months (beige) and 6 months (yellow) post-outbreak. D. log anti-H:d IgM concentration amongst participants without persistent fever, comparing titres at 3 months (beige) and 6 months (yellow) post outbreak. E. log anti-H:d IgG concentration amongst participants without persistent fever, comparing titres at 3 months (green) and 6 months (purple) post-outbreak. F. log anti-H:d IgM concentration amongst participants without persistent fever, comparing titres at 3 months (green) and 6 months (purple) post-outbreak. All graphs: red crossbar shows median antibody concentration; brackets show p-values (Wilcoxon signed rank test)
