  1. a Numbers represent sequences and can exceed the numbers of strains due to heterozygous individuals
  2. b π = Nucleotide Diversity
  3. c θ SITE = Watterson's Theta per site
  4. d HD = Haplotype diversity
  5. Colombia and Venezuela are designated NA; the rest of the world, corresponding to available sequences from other geographical origins, is designated R; and worldwide, corresponding to the combination of the two previous designations, is labeled W (W = NA +R).
