The strain of cholera that has sickened thousands in Haiti came from a single source and was not repeatedly introduced to the island over the past three years as some have thought.
The cholera strain that transferred to Haiti in 2010 has multiple toxin gene mutations that may account for the severity of disease and is evolving to be more like an 1800s version of cholera.

United Nations agencies said on Friday that a dangerous cholera epidemic is spreading quickly in Guinea-Bissau, where campaigning for an upcoming election could put even more people at risk.
Vibrio cholerae is a gram negative comma-shaped bacterium with a polar flagellum that causes cholera in humans. V. cholerae belongs to the gamma subdivision of the Proteobacteria. Classical and El Tor are the two types of V. Cholerae identified by hemaggluttination testing. El Tor is found throughout the world, while the classical biotype is found only in Bangladesh. It was first isolated as the cause of cholera by Italian anatomist Filippo Pacini in 1854; however, this discovery was not...
