Worldwide distribution of pathogen and viral richness and genetic diversity for HLA. (A) Pathogen richness; (B) Viral richness; (C) HLA-B genetic diversity as estimated with polymorphism informative content (PIC) as a proxy for HLA class I diversity; HLA-DRB1 genetic diversity as estimated with PIC as a proxy for HLA class II diversity.
