Fig 5. Shared and unique Plasmodium vivax multilocus genotypes within cluster #3 from Gleba Porto Luiz, Acrelândia, Brazil, during four rounds of reactive case detection (days 0, 30, 60, and 180).

We used the same color code as in Fig 1 to indicate the index HH (red), neighbor HHs (orange), and control HHs (black). Predominant or only genotypes found in each sample are identified with numerals; those recovered from the index case are underlined. Predominant genotypes shared by ≥ 2 parasite samples within the cluster were circled; for example, two index HH members shared the same predominant genotype (#81) on day 0. Identical superscript letters indicate groups of samples harboring parasite lineages (e.g., parasites recovered on day 60 from the index case—whose major genotype is #53—and one neighbor HH member [whose major genotype is #94]) that were considered genetically similar when analyzing both major and minor alleles although not identical (see main text for definition).
