No matter what, where, or who you are, water is a necessary component to keeping any organism alive. Although water is essential for life, in many places, clean drinking water is hard to find. There are many consequences to drinking contaminated water. Every year, three to five million people are attacked by water-borne diseases and over 100,000 of them die. One fatal disease that can kill within hours is cholera. Cholera is a water-borne disease caused by the spreading of toxins throughout the intestines by the Vibrio Cholerae bacterium. Bad hygiene and other unsanitary conditions such as contamination of food and water can result in this unpleasant infection. As stated in the Gale Encyclopedia of Medicine, “contamination starts when a person infected with cholera steps into a community water supply.” Cholera is more common in places with poor cleanliness and insufficient water treatment. These locations include environments consisting of brackish rivers and coastal waters such as an underdeveloped country like Africa. Cholera can affect anyone but is usually targeted at younger ch...
Usually, they were emptied by the ‘soil men’ at night. These men took the solid human waste away. However, in poorer places, the solid waste was just thrown in a large pile close to the houses. The liquid from the toilets including the waste seeped down into the earth and contaminated the water supplies. These liquids carried diseases causing germs to grow in the water. The most frightening disease of all was cholera. Many families dealt with cholera and many did not survive. Cholera originated from India. It quickly spread from Russia and Asia then eventually Europe during the industrial revolution. By this time Cholera has already reached London in February 1832. Cholera is a violent sickness and diarrhoea. It causes dehydration and loss of Blood fluid in the body. Over 50% of families who contracted the disease died within 24hours of showing symptoms. During the early 19th Century working class Families had no knowledge how the disease was contracted and was thought it was transmitted from poisons, foul smelling air. It was only in 1849 that it killed 70,000 people until Dr. John Snow then discovered that cholera bacteria was contracted from polluted
Lack of technology contributed to the fact that cholera couldn’t be studied in isolation during the 1854 outbreak. With the lack of technology there was also the lack of knowledge. The idea of germs living inside the water was an absurd idea because no one could see those
As a young boy, John Snow envisioned himself becoming a physician at the young age of fourteen. His parents seen how intelligent and eager of a student he was, so they decided to send him to a private school. Due to his excelled abilities in looking at details, he was able to get an apprenticeship. Dr. William Hardcastle took interest in him due to his analytical mind, and gave him the opportunity to become his apprentice. During his apprenticeship in 1831 at the age of only eighteen, an epidemic of cholera hit London. This epidemic was not new to the European continent it had already claimed hundreds of thousands of lives already. Being unable to see all the patients personally Dr. Harcastle decided to send Snow to Killingworth Colliery to
Smallpox is a disease from the variola virus. Smallpox has caused an estimated number of 300 million deaths in the 1900s alone. Smallpox is said to have been around since the ancient Egyptian times. The disease was eradicated in the late 20th century and two samples are still kept, one in U.S.A and one in Russia. Smallpox creates bumps and blisters all over the body and has been one of the most fatal epidemics the world has seen.
There are two types of bacteria that cause Typhus, Rickettsia Typhi and Rickettsia Prowazekii. The form of Typhus depends on which type of bacteria has entered the body and caused the infection. Rickettsia Typhi causes Murine or Endemic Typhus. Endemic Typhus is unusual in the United States. When it is found, its usually seen in areas with poor hygiene and where the temperature is cold. Endemic typhus is sometimes called "jail fever." Murine Typhus typically occurs in the southeastern United States, often during the summer and fall. Risk factors for Murine Typhus include exposure to rat fleas or rat feces. Rickettsia Prowazekii causes both Epidemic Typhus and Brill-Zinsser disease. Brill-Zinsser disease is a far more mild form of Epidemic Typhus. It occurs when the disease re-activates in a person who was previously infected. It is more common in the elderly. Lice and fleas of flying squirrels spread the bacteria. There is no commercially available vaccine against either Endemic or Epidemic typhus.
While cholera is rare in the United States, it is a bacteria disease that affects the intestinal tract, by a germ called Vibrio cholerae (NYSDOH, 2017). The way it is diagnosed is through a stool sample (NYSDOH, 2017). The symptoms of cholera start to appear hours to five days after drinking water, or eating contaminated food (NYSDOH, 2017). The signs of cholera are nausea, vomiting, and diarrhea, which leads a person to feel weak and tired(NYSDOH,
In For the World’s Poor, Drinking Water Can Kill people are drinking non-potable water that causes billions
In 1854, Dr. John Snow performed a study in London that led to his discovery of the disease’s main source. He was able to trace it to the poor sewer, waste, and water management from one of the major water sources of London residents, the “Broad Street pump”. When this water pump was removed, the deaths by cholera slowed and eventually stopped. Although he had not Symptoms include vomiting, nausea, and abdominal pain along with the more severe symptoms - dehydration and diarrhea. Unlike other forms of bacterial gastroenteritis, the diarrhea is not bloody, but instead very watery.
Cholera is an acute diarrheal disease caused by infection of the intestine with the bacterium Vibrio cholera (n.d.). Retrieved from http://www.cdc.gov/cholera/general/). Number of researches has been conducted and it has concluded that thousands of people are infected around the world. For more than two centuries, cholera has evaded some of the top scientist and still remains a threat to the world populations. A major cholera epidemic began in India in 1817, from India the disease spread to Russia, appearing at rapid speed and crossing all across the continent. Cholera is believed to originate in 1817 at the Ganges River in India and then later spread to other areas and regions due to poor removal of water mainly from British ships.
Tuberculosis (TB) is an infectious disease that is caused by bacteria that belongs to the Mycobacterium tuberculosis complex. Although Tb can affect other parts of the body, it mainly attacks the lungs (pulmonary) (Dye et al. 1999).What makes TB dangerous socially is that its pulmonary form is infectious and can be spread through contact of the infectious droplets. The most widespread mechanism of Tb spread is the cough. However, the infection spread requires prolonged contact with a patient and mostly the members of the same household are at risk. The issue of TB has lingered for years and continues to be a major public health problem within England, Tower Hamlets especially (Department of Health, 2010). The most reported cases of TB in the United Kingdom are in London and the more deprived boroughs around it. The rise in TB cases in the area of Tower Hamlets was seen mainly in the non-UK born residents, particularly those with origins from areas with high TB incidence like Sub-Sahara Africa, Indian Subcontinent and East Europe). Another group with high prevalence is the socially disadvantaged and included the homeless, drug users and prisoners (NHS, 2012).
The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is “a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum” (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration that can occur, but it is only fatal if treatment is not administered as soon as possible. This research paper includes information on the causes of cholera, symptoms, ways of treatment, studies of treatments, complications that may occur, the tests and diagnosis for cholera, and finally, the ways the cholera bacterium may be transmitted.
Cholera is a disease caused by bacteria and spreads trough contaminated water. The dangerous phase of cholera is the grater loss of fluid from the body in a short span of time. In a more severe scenario, it may produce diarrhea within few hours of consumption of contaminated water.
Infants, young children, elderly people, and people with underlying health conditions are most likely to get cholera because of their high risk of dehydration. On top of that, in areas with inadequate treatment of sewage and drinking water like Haiti, Southeast Asia, and Africa, cholera spreads very quickly. Cholera is a global disease that spreads to different countries by international travel or imported goods such as contaminated seafood. On a yearly basis, there are about 100,000...
Water Scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need causing them to die. This eventually affects the global population. Therefore many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling.
Many people around the world need water. Around 780 million people are unable to get clean water (One Billion Affected). People who do have access to clean water in their homes, have to pay a fee. The people who struggle to live obviously do not have enough money to buy water. People who are unable to have clean water have a good chance of dying either from disease or from dehydration. At least 3.4 million people die a year from water problems such as sanitation (One Billion Affected).
