Cholera diarrhea can look like cloudy rice water. Cholera can cause death from dehydration (the loss of wate A confirmed cholera case is any suspected case in which Vibrio cholerae O1 or O139 is confirmed by culture or polymerase chain reaction (PCR) test. In countries where cholera is not present or has been eliminated, the case is confirmed if Vibrio cholerae O1 or O139 is toxigenic. After a cholera outbreak has been identified Studying cholera has led to the development of new epidemiological methods that have helped to illuminate not only cholera transmission but the whole science of infectious disease epidemiology. It was John Snow in London in the 1800s who originally established a causal link between cholera transmission and exposure to contaminated water ( Figure 1 )

However, there are an estimated 3 million cases of diarrheal illness and approximately 100,000 deaths worldwide caused by V. cholerae annually [ 2 ] Estimating the true prevalence of cholera. Successful development of anti-cholera measures requires accurate estimates of infection incidence. Reporting of cholera cases, however, typically relies on clinical assessment at the time of patient presentation and can be problematized by lack of access to health care and variable, nonspecific symptomatology

  2. IMPORTANCE In this genomic epidemiology study, we have applied high-resolution whole-genome-based sequence typing methodologies on a comprehensive set of genome sequences that have become available in the aftermath of the Haitian cholera epidemic. These sequence resources enabled us to reassess the degree of genomic heterogeneity within the Vibrio cholerae O1 serotype and to refine boundaries.
  3. Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance

The main cause of death from acute diarrhoea is dehydration, which results from the loss of fluid and electrolytes in diarrhoeal stools. Other important causes of death are dysentery and undernutrition. Diarrhoea is an important cause of undernutrition. This is because patients eat less during diarrhoea and their ability to absorb nutrients is reduced; moreover, nutrient requirements are.

Cholera is a severe form of waterborne acute dehydrating diarrhoeal disease which is well known for its epidemic and pandemic potentials [Reference Kaper, Morris and Levine 1, Reference Mukhopadhyay, Takeda and Nair 2].Cholera continues to be a major public health problem, particularly in developing countries where access to potable drinking water and hygienic sanitation.

The role of the aquatic environment on maintenance of cholera dynamics depends on the sanitary condition of the community. Endemism in a well-sanitize Kingdom, reporting of cholera was compulsory.

SUMMARY Cholera caused by toxigenic Vibrio cholerae is a major public health problem confronting developing countries, where outbreaks occur in a regular seasonal pattern and are particularly associated with poverty and poor sanitation.

There is a relationship between the endemicity of cholera and the immunity or subimmunity of the population of some geographic areas to Vibrio - cholerae infection. The basis of cholera endemnicity has yet to be fully elucidated. Cholera may spread to other regions of the world experiencing warm temperatures achieving epidemic or pandemic status Basic epidemiology was originally written with a view to strengthening education, training and research in the field of public health. Since the book was published in 1993, more than 50 000 copies have been printed, and it has been translated into more than 25 languages. A list of these languages and contact addresses of loca issues of what to do to control cholera are largely known, context-specific practices on how to do it in order to surmount challenges to coordination, logistics, insecurity, access, and politics, remain.

Cholera Fact Sheet What is cholera? Cholera is an acute diarrheal illness caused by certain strains of the bacterium Vibrio cholerae. Who gets cholera? In the United States, cholera occurs in persons who travel to foreign countries where outbreaks of cholera are occurring and who drink contaminated water and food there, or those who eat raw o development of epidemiology. One of them was John Snow. In 1849, John Snow, an English physician, formulated and tested a hypothesis concerning the origin of an epidemic of cholera in London. On the basis of the available data snow postulated that cholera was transmitted by contaminated water through a then unknown mechanism

Example: 1854 London cholera outbreak Snow and his map-persuaded the local council to disable the well pump by removing its handle, e ectively ending the outbreak.-convinced the scienti c community that cholera was a waterborne illness, and not transmitted by air.
