aVariations in parasite prevalence between different time periods at each study site were compared using Tukey-Kramer HSD test of analysis of variance (ANOVA) with repeated measures
bVariations in vector densities between different time periods at each study site were compared using non-parametric Wilcoxon rank-sum tests
