Dysentery in the context of Fever

Diarrhea (American English), also spelled diarrhoea or diarrhœa (British English), is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal.

The most common cause is an infection of the intestines due to a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two weeks, which can be either watery or bloody). The short duration watery diarrhea may be due to cholera, although this is rare in the developed world. If blood is present, it is also known as dysentery. A number of non-infectious causes can result in diarrhea. These include lactose intolerance, irritable bowel syndrome, non-celiac gluten sensitivity, celiac disease, inflammatory bowel disease such as ulcerative colitis, hyperthyroidism, bile acid diarrhea, and a number of medications. In most cases, stool cultures to confirm the exact cause are not required.

Louis IX (25 April 1214 – 25 August 1270), also known as Saint Louis, was King of France from 1226 until his death in 1270. He is widely recognized as the most distinguished of the Direct Capetians. Following the death of his father, Louis VIII, he was crowned in Reims at the age of 12. His mother, Blanche of Castile, effectively ruled the kingdom as regent until he came of age, and continued to serve as his trusted adviser until her death. During his formative years, Blanche successfully confronted rebellious vassals and championed the Capetian cause in the Albigensian Crusade, which had been ongoing for the past two decades.

As an adult, Louis IX grappled with persistent conflicts involving some of the most influential nobles in his kingdom, including Hugh X of Lusignan and Peter I of Brittany. Concurrently, England's Henry III sought to reclaim the Angevin continental holdings, only to be decisively defeated at the Battle of Taillebourg. Louis expanded his territory by annexing several provinces, including parts of Aquitaine, Maine, and Provence. Keeping a promise he made while praying for recovery from a grave illness, Louis led the ill-fated Seventh and Eighth Crusades against the Muslim dynasties that controlled North Africa, Egypt, and the Holy Land. He was captured and ransomed during the Seventh Crusade, and later succumbed to dysentery during the Eighth Crusade. His son, Philip III, succeeded him.

The Morea expedition (French: Expédition de Morée) is the name given to the land intervention of the French Army in the Peloponnese between 1828 and 1833, at the time of the Greek War of Independence, with the aim of expelling the Ottoman-Egyptian occupation forces from the region. It was also accompanied by a scientific expedition mandated by the French Academy.

After the fall of Messolonghi in 1826, the Western European powers decided to intervene in favour of revolutionary Greece. Their primary objective was to force Ibrahim Pasha, the Ottoman Empire's Egyptian ally, to evacuate the occupied regions and the Peloponnese. The intervention began when a Franco-Russo-British fleet was sent to the region and won the Battle of Navarino in October 1827, destroying the entire Turkish-Egyptian fleet. In August 1828, a French expeditionary corps of 15,000 men led by General Nicolas-Joseph Maison landed in the southwestern Peloponnese. During October, soldiers took control of the principal strongholds still held by the Turkish troops. Although the bulk of the troops returned to France in early 1829 after an eight month-deployment, the French kept a military presence in the area until 1833. The French army would suffer about 1,500 dead, mainly due to fever and dysentery.

The Caspian expeditions of the Rus' were military raids undertaken by the Rus' between the late 9th century and c. 1041 on the Caspian Sea shores, of what are nowadays Iran, Dagestan, and Azerbaijan. Initially, the Rus' appeared in Serkland in the 9th century travelling as merchants along the Volga trade route, selling furs, honey, and slaves. The first small-scale Viking raids took place in the late 9th and early 10th century. The Rus' undertook the first large-scale expedition in 913; having arrived on 500 ships, they pillaged in the Gorgan region, in the territory of present-day Iran, and more to the west, in Gilan and Mazandaran, taking slaves and goods. On their return, the northern raiders were attacked and defeated by the Khazars in the Volga Delta, and those who escaped were killed by the local tribes in the middle Volga.

During their next expedition in 943, the Rus' captured Bardha'a, the capital of Arran, in the modern-day Republic of Azerbaijan. The Rus' stayed there for several months, killing many inhabitants of the city and amassing substantial plunder. It was only an outbreak of dysentery among the Rus' that forced them to depart with their spoils. Sviatoslav, prince of Kiev, commanded the next attack, which destroyed the Khazar state in 965. Sviatoslav's campaign established the Rus's hold on the north-south trade routes, helping to alter the demographics of the region. Raids continued through the time period with the last Scandinavian attempt to reestablish the route to the Caspian Sea taking place in c. 1041 by Ingvar the Far-Travelled.

Leo II (Ancient Greek: Λέων, Leōn; c. 467 – 474), called the Younger, briefly reigned as a child emperor of the Eastern Roman Empire from 473 to 474. He was the son of Zeno, the Isaurian general and future emperor, and Ariadne, a daughter of the emperor Leo I (r. 457–474). Leo II was made co-emperor with his grandfather Leo I on 17 November 473, and became sole emperor on 18 January 474 after Leo I died of dysentery. His father Zeno was made co-emperor by the Byzantine Senate on 29 January, and they co-ruled for a short time before Leo II died in late 474. He is sometimes surnamed with the epithet "the Small" (Latin: Minor; Ancient Greek: ὁ Μικρός), probably to distinguish him from his grandfather and augustus Leo I (Ancient Greek: ὁ Μέγας, romanized: ho Mégas, lit. 'the Great').

The Eighth Crusade was the second Crusade launched by Louis IX of France, this one against the Hafsid dynasty in Tunisia in 1270. It is also known as the Crusade of Louis IX Against Tunis or the Second Crusade of Louis. The Crusade did not see any significant fighting as Louis died of dysentery shortly after arriving on the shores of Tunisia. The Treaty of Tunis was negotiated between the Crusaders and the Hafsids. No changes in territory occurred, though there were commercial and some political rights granted to the Christians. The Crusaders withdrew back to Europe soon after.

Nathaniel Bacon (January 3, 1647 – October 26, 1676) was an English merchant adventurer who immigrated to the Virginia Colony, where he sat on the Governor's Council. In early 1676 he led Bacon's Rebellion against the Virginia government. The rebellion was briefly successful; but after Bacon’s death from dysentery in October 1676, the rebel forces collapsed.

Bergen-Belsen (pronounced [ˈbɛʁɡn̩ˌbɛlsn̩]), or Belsen, was a Nazi concentration camp in what is today Lower Saxony in northern Germany, southwest of the town of Bergen near Celle. Originally established as a prisoner of war camp, in 1943, parts of it became a concentration camp. Initially this was an "exchange camp", where Jewish hostages were held with the intention of exchanging them for German prisoners of war held overseas. The camp was later expanded to hold Jews from other concentration camps.

After 1945, the name was applied to the displaced persons camp established nearby, but it is most commonly associated with the concentration camp. From 1941 to 1945, almost 20,000 Soviet prisoners of war and a further 50,000 inmates died there. Overcrowding, lack of food, and poor sanitary conditions caused outbreaks of typhus, tuberculosis, typhoid fever, and dysentery, leading to the deaths of more than 35,000 people in the first few months of 1945, shortly before and after the liberation.

Theodora (Greek: Θεοδώρα; c. 815 – c. 867), sometimes called Theodora the Armenian or Theodora the Blessed, was Byzantine empress as the wife of Byzantine emperor Theophilos from 830 to 842 and regent for the couple's young son Michael III, after the death of Theophilos, from 842 to 856. Theodora is most famous for bringing an end to the second Byzantine Iconoclasm (814–843), an act for which she is recognized as a saint in the Eastern Orthodox Church. Though her rule saw the loss of most of Sicily and failure to retake Crete, Theodora's foreign policy was otherwise highly successful; by 856, the Byzantine Empire had gained the upper hand over both the Bulgarian Empire and the Abbasid Caliphate, and the Slavic tribes in the Peloponnese had been forced to pay tribute, all without decreasing the imperial gold reserve.

Possibly of Armenian descent, Theodora was born into a rural family of traders and military officials in Paphlagonia. In 830 she was selected by Euphrosyne, step-mother of the emperor Theophilos, as a candidate in a bride-show for the young emperor. After being chosen by Theophilos she was crowned empress on 5 June 830. Theophilos was an iconoclast, who opposed the veneration of icons; it is unclear how aware he was that Theodora was an iconophile. The couple had seven children and Theodora was a loyal participant in imperial affairs and ceremonies, but she continued to secretly venerate icons throughout her husband's reign. Theophilos died of dysentery on 20 January 842, probably younger than 30. On his deathbed, he named Theodora as regent for their two-year-old son Michael III and designated a selection of advisors to assist her. The most prominent of these advisors was the logothete and eunuch Theoktistos, who would become a close confidant of Theodora.

Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, and typhoid.

Shigella is a genus of bacteria that is Gram negative, facultatively anaerobic, non–spore-forming, nonmotile, rod shaped, and is genetically nested within Escherichia. The genus is named after Kiyoshi Shiga, who discovered it in 1897.

Shigella causes disease in primates, but not in other mammals; it is the causative agent of human shigellosis. It is only naturally found in humans and gorillas. During infection, it typically causes dysentery.

Chronic diarrhea (alternate spelling: diarrhoea) of infancy, also called toddler's diarrhea, is a common condition typically affecting up to 1.7 billion children between ages 6–30 months worldwide every year, usually resolving by age 4. According to the World Health Organization (WHO), diarrheal disease is the second greatest cause of death in children 5 years and younger. Diarrheal disease takes the lives of 525,000 or more children per year. Diarrhea is characterized as the condition of passing of three or more loose or watery bowel movements within a day sometimes with undigested food visible. Diarrhea is separated into three clinical categories; acute diarrhea may last multiple hours or days, acute bloody diarrhea, also known as dysentery, and finally, chronic or persistent diarrhea which lasts 2–4 weeks or more. There is normal growth with no evidence of malnutrition in the child experiencing persistent diarrhea. In chronic diarrhea there is no evidence of blood in the stool and there is no sign of infection. The condition may be related to irritable bowel syndrome. There are various tests that can be performed to rule out other causes of diarrhea that don't fall under the chronic criteria, including blood test, colonoscopy, and even genetic testing. Most acute or severe cases of diarrhea have treatment guidelines revolving around prescription or non prescription (also known as over the counter or OTC) medications based on the cause, but the treatment protocols for chronic diarrhea focus on replenishing the body with lost fluids and electrolytes, because there typically isn't a treatable cause.

In the history of the United States, American pioneers built overland trails throughout the 19th century, especially between 1840 and 1847 as an alternative to sea and railroad transport. These settlers began to settle much of North America west of the Great Plains as part of the overland mass settlements of the mid-19th century. Settlers emigrating from the eastern United States did so with various motives, among them religious persecution and economic incentives, to move from their homes to destinations further west via routes such as the Oregon, California, and Mormon Trails. After the end of the Mexican–American War in 1848, vast new American conquests of territory again encouraged mass settlement. Legislations like the Donation Land Claim Act and significant events like the California Gold Rush further encouraged settlers to travel overland to the north.

Two major wagon-based transportation networks, one typically starting in Missouri and the other in the Mexican province of Santa Fe de Nuevo México, served the majority of settlers during the era of westward expansion. Three of the Missouri-based routes—the Oregon, California, and Mormon Trails—were collectively known as the Emigrant Trails. Historians have estimated at least 500,000 emigrants used these three trails between 1843 and 1869, and despite growing competition from transcontinental railroads, some use even continued into the early 20th century. The major southern routes were the Santa Fe, Southern Emigrant, and Old Spanish Trails, as well as its wagon road successor the Mormon Road, a southern spur of the California Trail used in the winter that also made use of the western half of the Old Spanish Trail. Regardless of the trail used, the journey was often slow and arduous, fraught with risks from dysentry, infectious diseases, dehydration, malnutrition, cholera, highwaymen, Indian raids, injury, and harsh weather, with as many as one in ten travelers dying along the way, usually as a result of disease.

Field Marshal FitzRoy James Henry Somerset, 1st Baron Raglan, GCB, PC (30 September 1788 – 28 June 1855), known before 1852 as Lord FitzRoy Somerset, was a British Army officer. When a junior officer, he served in the Peninsular War and the Waterloo campaign, latterly as military secretary to the Duke of Wellington. He also took part in politics as Tory Member of Parliament for Truro, before becoming Master-General of the Ordnance.

He became commander of the British troops sent to the Crimea in 1854: his primary objective was to defend Constantinople, and he was also ordered to besiege the Russian port of Sevastopol. After an early success at the Battle of the Alma, a failure to deliver orders with sufficient clarity caused the fateful Charge of the Light Brigade at the Battle of Balaclava. Despite further success at the Battle of Inkerman, a poorly coordinated allied assault on Sevastopol in June 1855 was a complete failure. Raglan died later that month, after having dysentery and depression.

Travelers' diarrhea (TD) is a stomach and intestinal infection experienced during travel to a new location as a result of lack of immunity to local food-borne pathogens. TD is defined as the passage of unformed stool (one or more by some definitions, three or more by others) while traveling. It may be accompanied by abdominal cramps, nausea, fever, headache and bloating. Occasionally dysentery may occur. Most travelers recover within three to four days with little or no treatment. About 12% of people may have symptoms for a week.

Bacteria are responsible for more than half of cases, typically via foodborne illness and waterborne diseases. The bacteria enterotoxigenic Escherichia coli (ETEC) are typically the most common except in Southeast Asia, where Campylobacter is more prominent. About 10 to 20 percent of cases are due to norovirus. Protozoa such as Giardia may cause longer term disease. The risk is greatest in the first two weeks of travel and among young adults. People affected are more often from the developed world.
