Fig 6. Shared and unique Plasmodium vivax multilocus genotypes within cluster #4 from Gleba Porto Luiz, Acrelândia, Brazil, during four rounds of reactive case detection (days 0, 30, 60, and 180).

The index, neighbor, and control HHs are shown in red, orange, and black, respectively; predominant or only genotypes were identified with numerals and those recovered from the index case were underlined. Predominant genotypes shared by ≥ 2 parasite samples within the cluster were circled. Identical superscript letters indicate groups of samples harboring parasite lineages that were considered genetically similar although not identical (see main text for definition).
