How cholera has spread from the Bay of Bengal
A major cholera pandemic has spread in at least three waves from a single global source: the Bay of Bengal.
A study in Nature reveals cholera's spread over the last 60 years into Asia, Africa, Europe and the Americas, continent-hopping on long-haul flights.
