Fig 4. Abundance of viral haplotypes in two E1 gene amplicons.
Heat maps indicating the relative abundance (red colour intensity) of distinct amino acid viral haplotypes following deep sequencing of two amplicons COF 1 (A) and CIF 2 (B) that span the near full-length CHIKV E1 gene in 25 Mexican patients. Dendrograms represent clustering of patients according to haplotype diversity.
