    Neutralizing antibody (N.A) profile in 34 pair serum samples obtained from 34 individuals who were DENV IgG positive pre-dengue season and demonstrated elevated DENV IgG after the season versus patient group. Neutralizing activity was determined by PRNT50 on BHK cells (A) and on FcγR-expressing BHK cells (B); Positive PRNT samples were defined as having a N.A ≥ 10 or Log2(PRNT50) ≥3.32 to any of the virus test (above dotted line). Non patient 1=pre-dengue season group; Non patient 2 = post-dengue season group; Patient = patient group. The results were represented as means of Log2 (N.A titers) ± SD. (PDF 314 kb

    Additional file 7. Predictive factors of seropositivity against Plasmodium vivax in the study area at survey 1 and survey 6. Multivariate risk factor analysis of seropositivity against P. vivax in the study area at survey 1 (n = 330) and survey 6 (n = 304); NS not significant in univariate analysis, therefore not included in multivariate model; NA variable measured during survey, therefore not relevant for seropositivity at survey 1
