Geographical distribution of samples and serology testing results. Each point on the map represents a Demographic and Health Survey sampling cluster; clusters with no children testing positive are transparent. (A) Sampling clusters with children positive by enzyme-linked immunosorbent assay (ELISA) for antibodies against dengue virus (DENV), Zika virus (ZIKV), and/or yellow fever virus (YFV). (B) Sampling clusters with children positive for neutralizing antibodies against each of the three viruses. (C) Sampling clusters with children positive for antibodies against YFV by ELISA and neutralization assay overlaid on locations of known YFV outbreaks as reported by the World Health Organization.61 This figure appears in color at www.ajtmh.org.
