Talk:Cholera

Suggestion for edit: 4 December 2021

I’ve just had a student completely misunderstand the history of cholera in Europe due to information missing from this article. I refer to the following paragraphs:

"The word cholera is from Greek: χολέρα kholera from χολή kholē "bile". Cholera likely has its origins in the Indian subcontinent as evidenced by its prevalence in the region for centuries.[14]

"The disease appears in the European literature as early as 1642, from the Dutch physician Jakob de Bondt's description it in his De Medicina Indorum.[87] (The "Indorum" of the title refers to the East Indies. He also gave first European descriptions of other diseases.)"

The issue is that the article jumps from Ancient Greek etymology to the 1642 European description of the disease modernly called cholera, with no explanation that the word "cholera" was historically used by physicians to refer to any gastrointestinal upset resulting in yellow diarrhea; de Bondt simply used a word already in common use to describe the new disease, a common practice of the time. In fact, it's only in the 1830s that the name for severe yellow diarrhea changes in English from "cholera" to "cholera morbus" to differentiate it from what was then known as "Asiatic cholera".

This misled my student into thinking that the word "cholera" was used historically to refer to only this disease, and specifically led them to think that Vibrio cholerae existed in Tudor England. (The word can be found in the Letters and Papers of Henry VIII.) A few words about the definition changing over time might be appropriate to prevent anyone else making the same mistake. 24.76.103.169 (talk) 16:22, 4 December 2021 (UTC)

I agree this would be good. Would you be able to make this change (or someone else)? EMsmile (talk) 11:03, 18 May 2022 (UTC)

Quote Risk factors for the disease include poor sanitation, insufficient clean drinking water, and poverty. Unquote Poverty is the status of having little or no money. There is no factual proof that that is a risk factor for whatever illness, as neither is e.g. illiteracy. It is merely the increased occurrence of certain illnesses in socially less developed strata that is noticeable, but that is an indicative sociological aspect. 103.29.31.108 (talk) 18:07, 27 February 2024 (UTC)

A recent study of the University of Graz analysed the ability of the cholorea bacteria, to detect bile in the body. It uses the proteins ToxR and ToxS. Only after detecting bile, the bacterium begins to transform and produce the cholera toxin.

The study was published in elife Biochemistry and Chemical Biology. Here is the doi-link

That´s why I would like to make following Changes in the Block "Cause"

Actual: Transmission Cholera bacteria have been found in shellfish and plankton.[17]

Transmission is usually through the fecal-oral route of contaminated food or water caused by poor sanitation.[2] Most cholera cases in developed countries are a result of transmission by food, while in developing countries it is more often water.[17] Food transmission can occur when people harvest seafood such as oysters in waters infected with sewage, as Vibrio cholerae accumulates in planktonic crustaceans and the oysters eat the zooplankton.[22]

New:

Transmission Cholera bacteria have been found in shellfish and plankton.[17]

Transmission is usually through the fecal-oral route of contaminated food or water caused by poor sanitation.[2] While the bacterium is in a harmless stage in the water, it can recognise bile acid thanks to the ToxR and ToxS proteins. Only then does the bacterium remodel itself and start producing the cholera toxin.
