Dysentery vs. Cholera — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on March 18, 2024
Dysentery is an inflammation of the intestines causing severe diarrhea with blood, while cholera is characterized by watery diarrhea and vomiting, leading to rapid dehydration.

Key Differences
Dysentery primarily affects the intestine, causing inflammation and resulting in severe diarrhea, often with blood and mucus. It can be caused by both bacterial and protozoan pathogens, with the two main types being bacillary dysentery (caused by bacteria) and amoebic dysentery (caused by a protozoan). Symptoms include abdominal pain, fever, and urgent need to defecate. On the other hand, cholera is specifically caused by the bacterium Vibrio cholerae and is characterized by acute, watery diarrhea that can lead to rapid dehydration and even death if untreated. Unlike dysentery, cholera diarrhea typically does not contain blood or mucus.
While dysentery may result from various pathogens and is marked by bloody diarrhea, cholera is always caused by Vibrio cholerae bacteria and is noted for extremely watery diarrhea, known as "rice-water stools." The transmission of both diseases is primarily through the consumption of contaminated food or water, highlighting the importance of sanitation and clean water supplies. However, the presence of blood and mucus in the stool is more associated with dysentery, whereas cholera stools are watery and may lead to severe dehydration more quickly.
The treatment for dysentery often involves antibiotics for bacterial causes or specific antiprotozoal medications for amoebic dysentery, along with rehydration therapy. In contrast, cholera treatment primarily focuses on rehydration, using oral rehydration salts (ORS) to replace lost fluids and salts, and antibiotics can be used to shorten the duration and severity of the illness.
Prevention strategies for both dysentery and cholera include ensuring access to clean water, practicing good sanitation and hygiene, and in some cases, vaccination. However, cholera has a more widely available and utilized vaccine compared to dysentery, where vaccination is not commonly employed as a preventative measure.
Both dysentery and cholera can cause outbreaks, especially in areas with poor sanitation, after natural disasters, or in refugee camps. However, cholera outbreaks have the potential to be more rapid and widespread due to the highly infectious nature of the Vibrio cholerae bacterium and its ability to cause severe dehydration within hours.

Common Curiosities
Are there vaccines for dysentery and cholera?
Vaccines are available for cholera and are recommended in endemic areas or during outbreaks. For dysentery, vaccines are not commonly used, with prevention focusing on sanitation and hygiene.
Can dysentery and cholera be fatal?
Yes, both can be fatal if untreated, due to severe dehydration and other complications, but prompt and effective treatment greatly reduces the risk of death.
What is the main treatment for cholera?
The main treatment is rehydration, using oral rehydration salts (ORS), and in severe cases, intravenous fluids and antibiotics may be required.
What distinguishes dysentery from cholera?
Dysentery is characterized by bloody diarrhea caused by bacteria or protozoa, while cholera, caused by Vibrio cholerae, leads to severe watery diarrhea and rapid dehydration.
How are dysentery and cholera transmitted?
Both are primarily transmitted through the consumption of contaminated food or water, often in areas with poor sanitation.
Is bloody diarrhea more common in dysentery or cholera?
Bloody diarrhea is a hallmark of dysentery, whereas cholera produces watery, non-bloody diarrhea.
Can both dysentery and cholera be treated with antibiotics?
Antibiotics are used in the treatment of bacterial dysentery and severe
What are "rice-water stools" in cholera?
"Rice-water stools" refer to the characteristic watery diarrhea of cholera, which is pale, milky in appearance, and resembles water used to wash rice.
What are the implications of untreated cholera?
Untreated cholera can lead to severe dehydration, electrolyte imbalance, and shock, potentially resulting in death within hours if not managed promptly.
Why is sanitation important in controlling dysentery and cholera?
Improved sanitation reduces the risk of contamination of food and water sources, thereby decreasing the incidence of both dysentery and cholera.
What is the role of hygiene in preventing dysentery and cholera?
Good personal and food hygiene, along with access to clean water and proper sanitation, are crucial in preventing both diseases.
How quickly do symptoms appear after infection with cholera?
Cholera symptoms can appear within a few hours to 5 days after ingestion of the bacteria, typically leading to rapid dehydration.
How does one prevent amoebic dysentery?
Preventing amoebic dysentery involves drinking clean, treated water, practicing good food and personal hygiene, and avoiding raw or unclean foods in areas where the disease is common.
Can dysentery lead to long-term health issues?
Chronic amoebic dysentery can cause long-term health issues such as liver abscesses, colitis, and increased risk of colorectal cancer.
How does climate affect the spread of dysentery and cholera?
Both diseases can see increased spread in warmer climates and during rainy seasons, as these conditions can facilitate the contamination of water sources and increase the likelihood of outbreaks.
