Nearly All Cholera Epidemics Originate In Asia, Bacterial Genome Studies Show

Science: Asia is the cradle of almost every cholera epidemic, genome studies show
“…By sequencing and comparing hundreds of bacterial genomes, [scientists] have shown that all of the explosive epidemics of cholera in Africa and the Americas in the past half-century arose after the arrival of new strains that had evolved in Asia. The work, published in two Science papers this week, could put to rest an old debate about the role of environmental factors in cholera’s global burden…” (Kupferschmidt, 11/9).
