Figure 8 shows the frequency and individual regional coverage score, Iq(k), for each allele pair (see Equation 7) in North America. The top row corresponds to allele frequencies (HLA-A, HLA-B, and HLA-C), the second, third, fourth and fifth to Iq(k) for Ebola GP Zaire, Ebola GP Sudan, Ebola NP Zaire, and Ebola NP Sudan, respectively. This evidence concerns the gene HLA-B and Ebola hemorrhagic fever.
