Find out where the cholera originates from the world

According to the latest study by British scientists, the three major cholera outbreaks worldwide over the past few years have come from a single place: the Bay of Bengal in northeastern Indian Ocean.

Research conducted by Cambridge scientists, just published in Nature , shows that cholera spread over the past 60 years in Asia, Africa, Europe and the Americas are rooted in Bengal , one of the largest bays in the world, is located in South Asia, through passengers on long-haul flights between countries and continents.

By investigating cholera bacteria at the genetic level, scientists have discovered the origin of the disease."We were surprised to see all the samples taken from 154 patients worldwide originating from the only place in the Bay of Bengal," said Nick Thomson, one of Cambridge's study authors. .

Every year in the world, there are 3 million to 5 million people infected and about 100,000 to 150,000 die because the disease seems to be not difficult to treat. Patients can easily die within a few hours if not supplied with clean water. For severe cases, the risk of death is between 30-50%.

The cholera, according to Dr Valerie Curties at London's School of Hygiene and Tropical Medicine, is " an embarrassing scandal of the 21st century by disease representing poverty; infrastructure, sanitation, drinking water. least".
