Multiplicity of Infection Is Poor Predictor of Village-Level P. vivax & P. falciparum Population Prevalence in Southwest Pacific

Across 8101 individuals in 46 villages, the proportion of spp. multiple clone infections (0%-53.8%) did not reflect prevalence by quantitative polymerase chain reaction (qPCR; 1.9%-38.4%), except for in Solomon Islands ( < .001). Thus this parameter was not informative to identify transmission foci. In contrast, prevalence by microscopy and qPCR correlated well.
