The 10 genotypes of HBV (A-J) also correspond to specific geographic distributions. [19] Genotype A is more frequently found in North America, northwestern Europe, India, and Africa, whereas genotypes B and C are endemic to Asia, and genotype D predominates in Eastern Europe and the Mediterranean. Type E is found in western Africa; type F, in South America; and type G, in France, Germany, Central America, Mexico, and the United States. Type H is prevalent in Central America; [8] type I, in Vietnam; and type J, in Japan. [19]
