Recommended: An essay on cholera outbreak
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.
Cholera is not particularly easy to catch. Although the microorganisms must have been plentiful during the nineteenth-century epidemics, many people probably ingested them without harm, for human stomach acids often kill the organisms before they reach the intestines where the trouble starts.
As the western world expand many people became ill with cholera because of overcrowding in living space, in some cities overcrowding often involved quarters below street level, where water was constantly seeping in the living area. In many Latin and African country the cholera virus is more common because of poor hygiene, poor sanitation and lack of education on public health. In an outbreak, the source of the contamination is usually the feces of an infected person that contaminates water or food. The disease can spread like wild fire in areas with poor treatment of sewage and drinking water. In Europe in the 1800s many people became infected with cholera because there water drawn from the nearby streams and rive...

...ury, one that moreover focused attention on the environmental evils of early industrial urbanization but it has been used to divert the attention from the carriers of the disease, the immigrants who travel to the U.S. daily. Travelers are advice to take caution when they areas visiting country’s with epidemic cholera (for example, parts of Africa, Asia, or Latin America) may be exposed to the cholera bacterium. Many case of cholera have been caused by contaminated seafood brought into the U.S. by travelers who have visited some of the listed countries above. Researchers are working very hard to find a way to stop the spread of cholera and make the public aware of the spread and harmful effects of being contaminated with cholera. It is imperative that everyone around the world have adequate sanitation and access to clean water so we can combat this horrific disease.
The book, The Ghost Map, tells the story of the cholera outbreak that took place in England during the medieval era. During this time, London became popular, causing it to become one of the most populous urban cities in England. However, it suffered from overcrowding, a large lower class, and little health regulations. As a result, living conditions and water supply were not the cleanest, and many died from the disease cholera. Though this epidemic led to many deaths/illnesses during it’s time, it has proven to be helpful and important to public health today. Some public health advancements that have occurred as a result include healthier, cleaner, and longer lives lived.
A.1 Concerning John Barnes, how was cholera communicated? What were the modes of disease transmission? What is the correct epidemiological term for the modes of transmission that were identified?
This book follows an esteemed doctor and a local clergyman who, together, are the heart of an investigation to solve the mystery of the cholera epidemic. In 1854 London was ravaged by a terrible outbreak of cholera, where within the span of mere weeks over five hundred people in the Soho district died. London, at the time, was a city of around two and a half million people, all crammed into a small area with no system for sewage removal. With overflowing cesspools, improper drainage of all the human and animal waste, and no system for guaranteed clean water, the people of London were in a bad state. They were essentially dumping all of their feces into their drinking water supply, a perfect environment for cholera to thrive.
There were “regulations against people washing clothes in or near waters used for drink, or against washing the entrails of beasts after slaughter”(Rowse 156). “…it is evident from innumerable documents how frequently they were broken” (Rowse 156). As long as people lived in small groups, isolated from each other, there were not many incidents of widespread disease. But as civilization progressed, people began clustering into cities. As the cities grew and became crowded, they also became the nesting places of water-borne, insect-borne, and skin-to-skin infectious diseases.
Han China and the Roman empire enjoyed great prosperity because of long-distance trade. Goods and ideas could travel farther than ever before, protected by these empires. However, when people move, they bring their germs with them. Since the trade networks were so vast, uniting places that might have never have had contact with each other, it was easy for diseases to travel. People didn’t have resistance to foreign diseases or medicine to counteract them, so epidemics were able to devastate entire populations. Sanitation in the Roman empire an...
In crowded conditions, the rate of infection is even more rapid. The diseases brought over to America were mainly spread by the respiratory method. The pathogenesis of infection is through the ingestion of contaminated food and water. Throughout Europe during the 15th century, food and water were contaminated with fecal matter and by unsanitary habits ( i.e. the lack of bathing). The traumatic route of infection is through insect and animal bites.
The rail market continued to grow and by the 1860’s all major cities within the United States were connected by rail. The main diseases that showed the most virulence during the time were cholera, yellow fever and consumption, now known as tuberculosis. The 9th census mortality data showed that 1 out 7 deaths from disease were caused by tuberculosis and 1 out of 24 disease deaths were resulting from cholera. . Until the 1870s the general consensus of the spread of disease through population was still the primitive idea that it came from the individual and not specifically the pathogen.... ... middle of paper ... ...
Hepatitis is the inflammation or swelling of the liver. The inflammation can happen from different injuries or viral forms of a disease. People who experience hepatitis have the symptoms of malaise, nausea, vomiting, loss of appetite, fever and jaundice. There are six known forms of Hepatitis which are Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E and Hepatitis G. The presence of hepatitis in the body can be very risky and cause severe death if not taken care of. Hepatitis is a severe issue that affect many people around the world like third world countries and cross contamination can occur mainly in health care places due to the exposure of patients with the disease and accidents handling blood or instruments, Hepatitis A,B,C,D,E and G are distinct diseases that differ in transmission and vaccines to prevent them or cure them.
By the 1840’s high rates of disease were ascribed to the housing many of New York’s poverty-stricken immigrants lived in. Fear spread that while disease was rooted in the polluted living conditions of New York’s poorer communities, disease could easily spread to the more well off citizens too. Public health officials realized that the city’s soiled streets and polluted sewers were a health risk to all New Yorkers. In the mid-nineteenth century, New York possessed a primitive sewage system. Poorly planned sewers spanned the city, but most citizens’ homes did not connect to these pipes. Instead, most New Yorkers relied on outdoor outhouses and privies. Because of the high levels of unmanaged waste, epidemics of infectious diseases were commonplace in New York. The city battled outbreaks of smallpox, typhoid, malaria, yellow fever, cholera, and tuberculosis. In 1849, a rash of cholera struck the city, killing more than five thousand people. A wave of typhoid in the mid-1860’s resulted in a similar amount of deaths. Port cities and transportation hubs, like New York, were especially prone to outbursts of infectious diseases because of the high volume of travelers that passed through the city. Americans realized that they were contracting and dying from infectious diseases at an alarming rate, but weren’t entirely sure of why or how. (Web, par. 17,
Although the Columbian Exchange allowed for the beneficial exchange of cultures, ideas, foods, and animals around the world during the 1450-1750 time period, it also had a dark side. One detrimental result of the Columbian Exchange would be the spreading of smallpox from Europe to the New World.

Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die. Children are more susceptible to the disease than adults, and in Africa, where ninety percent of the world’s cases occur and where eighty percent of the cases are treated at home, one in twenty children die of the disease before they reach the age of five. Pregnant women are also more vulnerable to disease and in certain parts of Africa, they are four times as likely to contract the disease and only half as likely to survive it.
The Flu is the common name influenza which is a virus that attacks the respiratory system. The flu virus releases its genetic information into the cells nucleus to replicate itself. When the cell dies, those copies are released and they affect other cells throughout the rest of the body. With that happening the virus weakens the immune system. When your sick with the flu, your body builds up a defense by making antibodies against it. The flu virus spreads through air when a person coughs, sneezes, or speaks.
Although preventive measures can be taken, over 21.5 million people annually become infected with Typhoid fever. In particular, areas with poor sanitation of water report higher rates of this disease. Typhoid fever is spread through contaminated water sources, making underdeveloped countries vulnerable to the infection.
