Although much is known about the mechanisms behind the spread of cholera, researchers still do not have a full understanding of what makes cholera outbreaks happen in some places and not others. Lack of treatment of human feces and lack of treatment of drinking water greatly facilitate its spread.

Popular medical practices, such as bloodletting, could not be effective in such a case. Snow also argued that cholera was not a product of Miasma. "There was nothing in the air to account for the spread of cholera". [25] According to Snow, cholera was spread by persons ingesting a substance, not through atmospheric transmittal. [25]
Cholera infections are most commonly acquired from drinking water in which V. cholerae is found naturally or into which it has been introduced from the feces of an infected person. Cholera is most likely to be found and spread in places with inadequate water treatment, poor sanitation, and inadequate hygiene.
Cholera: Spread by the bacterium Vibrio cholerae: Drinking water contaminated with the bacterium In severe forms it is known to be one of the most rapidly fatal illnesses known. Symptoms include very watery diarrhea, nausea, cramps, nosebleed, rapid pulse, vomiting, and hypovolemic shock (in severe cases), at which point death can occur in 12 ...
An 1831 color lithograph by Robert Seymour depicts cholera as a robed, skeletal creature emanating a deadly black cloud.. The miasma theory (also called the miasmic theory) is an abandoned medical theory that held that diseases—such as cholera, chlamydia, or the Black Death—were caused by a miasma (μίασμα, Ancient Greek for 'pollution'), a noxious form of "bad air", also known as ...
Cholera dissemination across Asia and Europe in 1817–1831. The first cholera pandemic (1817–24) began near Kolkata and spread throughout Southeast Asia to the Middle East, eastern Africa, and the Mediterranean coast. While cholera had spread across India many times previously, this outbreak went farther; it reached as far as China and the ...
An exhaustive study into environmental factors influencing the spread of cholera in Haiti cites above average air temperatures following the earthquake, "anomalously high rainfall" from September to October 2010, and damage to the limited water and sanitation infrastructure as likely converging to create conditions favorable to a cholera outbreak.
