Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked seafood is a common source. Humans are the only animal affected.
Cholera is an infectious disease caused by the bacterium Vibrio cholerae. It infects the small intestine.. There are many types (strains) of the Vibrio cholera bacteria. Some of them cause more serious illnesses than others.
Cholera caused more deaths, more quickly, than any other epidemic disease in the 19th century. The medical community now believes cholera to be exclusively a human disease, spread through many means of travel during the time, and transmitted through warm fecal-contaminated river waters and contaminated foods.
Preceding the 1854 Broad Street cholera outbreak, physicians and scientists held two competing theories on the causes of cholera in the human body: miasma theory and germ theory. The London medical community debated between these causes for the persistent cholera outbreaks in the city.
Cholera is an infectious disease that causes severe watery diarrhea, which can lead to dehydration and even death if untreated. It is caused by eating food or drinking water contaminated with a ...
The highest incidence of cholera occurred in 2011 immediately following the introduction of the primary exposure. The rate of incidence slowly declined thereafter, with spikes resulting from rainy seasons and hurricanes. As reported by the Haitian Health Ministry, as of August 2012, the outbreak had caused 586,625 cholera cases and 7,490 deaths.

Cholera is a bacterial disease usually spread through contaminated water. Cholera causes severe diarrhea and dehydration. Left untreated, cholera can be fatal in a matter of hours, even in previously healthy people.Modern sewage and water treatment have virtually eliminated cholera in industrialized countries. The last major outbreak in the United States occurred in 1911. But cholera is still present in Africa, Southeast Asia and Haiti. The risk of cholera epidemic is highest when poverty, wa...
Most people exposed to the cholera bacterium (Vibrio cholerae) don't become ill and never know they've been infected. Yet because they shed cholera bacteria in their stool for seven to 14 days, they can still infect others through contaminated water. Most symptomatic cases of cholera cause mild or moderate diarrhea that's often hard to distinguish from diarrhea caused by other problems.Only about 1 in 10 infected people develops more-serious signs and symptoms of cholera, usually within a few...
A bacterium called Vibrio cholerae causes cholera infection. However, the deadly effects of the disease are the result of a potent toxin called CTX that the bacterium produce in the small intestine. CTX binds to the intestinal walls, where it interferes with the normal flow of sodium and chloride. This causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).Contaminated water supplies are the main source of cholera infectio...
Everyone is susceptible to cholera, with the exception of infants who derive immunity from nursing mothers who have previously had cholera. Still, certain factors can make you more vulnerable to the disease or more likely to experience severe signs and symptoms. Risk factors for cholera include: 1. Poor sanitary conditions. Cholera is more likely to flourish in situations where a sanitary environment — including a safe water supply — is difficult to maintain. Such conditions are common to ref...
Cholera can quickly become fatal. In the most severe cases, the rapid loss of large amounts of fluids and electrolytes can lead to death within two to three hours. In less extreme situations, people who don't receive treatment may die of dehydration and shock hours to days after cholera symptoms first appear.Although shock and severe dehydration are the most devastating complications of cholera, other problems can occur, such as: 1. Low blood sugar (hypoglycemia). Dangerously low levels of bl...
Cholera is rare in the United States with the few cases related to travel outside the U.S. or to contaminated and improperly cooked seafood from the Gulf Coast waters.If you're traveling to cholera-endemic areas, your risk of contracting the disease is extremely low if you follow these precautions: 1. Wash hands with soap and water frequently, especially after using the toilet and before handling food. Rub soapy, wet hands together for at least 15 seconds before rinsing. If soap and water are...
