As a result, it is only necessary for us to test and monitor sources that humans come in contact with. Water is very important to humans, and it is abundant in microbes and pathogens. Since fecal matter is the main problem in water, fecal coliforms are commonly used to detect contamination. Some researchers focus on specifics areas and bodies of waters to test, while others even focus on protocols involved in testing water. Discussion of the time consuming process of testing for coliforms is discussed in “Comparison and Recovery of Escherichia coli and Thermotolerant Coliforms in Water.”…
Climate change may be a politically contentious issue, but the scientific community has reached a consensus: it is real and the effects could be disastrous (Hughes, 2003). Within the next century, there will be changes in rainfall patterns, rising sea-levels and significant temperature increases, as well as the impact these conditions will have on flora, fauna and disease transmission (Hughes, 2003). Of particular concern to Australia is how these changes will affect the transmission of Ross River Virus (RRV) and the survival of its mosquito vectors. Numerous scientific studies have shown how different species of mosquitoes worldwide are adapting to changing environmental climates, with several examining…
Our non-profit organization, Kleaner Corp, will help eliminate the problem of contaminated water in low-income countries. There are many countries in the world that are in need of clean water, like Ghana, India, and Afghanistan. Clean water in an essential requirement for human life. However, many people do not have access to it in developing or poor countries, and sometimes, clean water is unavailable even in developed countries in emergency situations. One of the greatest dangers after a natural disaster is waterborne diseases, such as the Guinea worm. In 1986, 3.5 million people were infected with Guinea worm disease just in South Asia and West Africa alone. In the world today, 783 million people currently do not have access to clean water.…

“Canada’s largest waterborne disease outbreak, which infected 1,346 people and killed six, was traced to runoff from livestock farms into a town’s water supply. The U.S. Geological survey found antimicrobial residue in 48 percent of the 139 streams…
In closing, the detailed work and years of researching the cholera epidemic has been a major building block for epidemiologists today. John Snow’s case studies and results have opened numerous doors for the public field and modern medicine.…
This paper will discuss the various different aspects of Cholera in Haiti and will outline the history of such a disease in terms of its epidemiology, natural reservoirs and vectors associated with it. The paper will describe how cholera is manifested, and what actions are recommended to manage, treat and help prevent the disease, and the important role nurses’ play in this process.…
Diseases can be defined as an abnormal condition that makes a person or country ill. It is usually accompanied by some type of signs or symptoms and some types of risk factors that it is originated from. This usually is resulting in a medical condition whether it can be physical or mental and sometimes leads to death. Diseases affect all persons whether it is domestically or internationally. Diseases can be a result of a person’s environmental conditions. This spread of disease is what is currently taking place in Haiti as discussed in articles written by the Wall Street Journal and The Global Post. There is an outbreak of the disease Cholera in Haiti that is affecting many people young and old.…

Vibrio Cholerae is a bacterium in the family of Vibrionaceae. This Gram-negative, facultative anaerobic, non-spore forming curved rod bacterium causes an acute diarrheal infection due to water or food ingested contaminated with bacterium Vibrio Cholerae. Cholera infects an estimated 3-5 million persons every year and causes about 100,000-120,000 deaths. There is a short incubation period of two hours to five days, which greatly enhances the potential of cholera’s dangerous outbreak pattern. About seventy-five percent of cases do not have any symptoms, even though the bacteria are present in their feces for 7-14 days post infection and are shed back into the environment, potentially infecting other people. Approximately 5% of infected persons will have severe disease characterized by profuse “rice water” like diarrhea, vomiting, and leg cramps. In these people, rapid loss of body fluids leads to dehydration and shock. Without treatment, death can occur within hours of infection.…
We all know of and have experienced many diseases during our lifetimes, ranging from the common cold, to the flu, and even strep throat. However, there are many diseases that are relatively unknown by the public, such as Ebola, Kuru, or Carpenter syndrome. Some diseases that, although not initially fatal, can become fatal if not known about or treated properly. In the case of some diseases, the side effects of it are even more deadly than the original disease itself. Therefore, it is critically important to discuss these diseases and understand them better. For that reason, I am here today to inform you about a disease known as Cholera, which has been gripping underdeveloped nations for decades.…
Bacteria infected water can be sensed by a bioelectronic nose that mimics a human nose. It works by finding the flavor the levels of bacteria that contaminates the water. The nose is very sensitive and can detect the earthy and musty scent from the tainted water.…
In the mid 1800s there were many outbreaks of cholera effecting and killing hundreds of people. It was in 1854 that a Doctor called John Snow discovered the cause behind the disease. Snow realised there was a link between cholera and water and meticulously researched this until there was no doubt that his theory was correct.…
Outbreak at Watersedge is a game that incorporates public health by creating a mystery to solve. An outbreak of severe diarrhea has taken place and the player must find the origin of the mini epidemic. The discovery game explores professional roles in public health, collecting data to support the conclusion and eventually finding out the cause of the outbreak. As a player, I mapped individual’s placement before they contracted the illness, collected information of where to take samples, review lab results, and found the source of the disease. Along the way, many public health professionals worked together to figure out the source of the outbreak.…
