1 WB, Western blot. Positivity defined as HTLV WB profiles of HTLV-1, HTLV-2, or HTLV untypeable.
2 Wald chi-square test of proportions significant at α = 0.05 by specimen status (eligible vs ineligible)
3 Wald chi-square test of proportions significant at α = 0.05 by HTLV status (seroreactive vs non-reactive)
4 Other ethnicities include, Bakela (n = 20), Bankutshu (n = 68), Basho (n = 12), Bambole (n = 1), and Dionga (n = 32).
