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.

The research by a team from Cambridge's Sanger Institute showed the infection is evolving, with the newest waves showing antibiotic resistance.

A UK expert said it was "a scandal" cholera was still affecting people.

1. No surprise. The Bay of Bengal is the world's largest open sewer.

2. The Ganges

This has been known for a while. I had a prof 30 years ago who was an expert on virulence factors in cholera. He said that the Ganges was the largest bacteria colony he could think of and the way that they prepared rice with that water was an ideal incubation method.
