Zoonotic And Vector-Borne Disease

Irrigation and domestication of animals led to an ideal environment for the spread of infectious epidemic diseases. Irrigation contributed to the spread of disease by transforming a naturally hot

1. The factors that are listed in 1.2 are world population growth, ecological disturbances, technological advancements, microbial evolution and adaptation, and human behavior and attitudes. World population growth can impact the spread because if we are looking at just one area of people that is extremely crowded and one of them has a disease; by person to person contact it can spread more easily compared to an area of people that is less compacted with people. Ecological disturbances such as climate changes, and natural disasters, can increase spreading of Zika because climate has a lot to do with where the mosquitos, and they also need places to live. If we had a natural disaster such as a flood, that is a lot of water and that’s what mosquitos

The conditions that contribute to the ability of diseases to flourish and spread are climate changes, globalization, urbanization, and creating medication that no longer kills the disease. These diseases are able to survive and become powerful because of they are able to evolve rapidly to our changing society.

The book chosen was “The New Killer Diseases”, because it seemed to be interesting and covered a great deal of information that was learned in class. The book discusses how we should fear the unknown when it comes to fighting the new killer diseases that could evolve and spread at any moment. It is scary to think at any moment that a new disease could develop causing an epidemic. The examples of stories of patients that were discussed made the book more interesting and easier to understand the concepts of the new diseases. The scientific research throughout the book gives readers a clear understanding how germs threaten all of mankind. We need to protect ourselves, families, and encourage the public to stay up to

An ‘emerging’ disease is one that is speedily increasing in frequency or distribution. This expression not only circumscribes the diseases corresponding with previously unknown agents, but additional known diseases that are ‘re-emerging’, as well. What is it that provokes disease emergence? Epidemiological principles profess that disease is multi-factorial. That is, in inclusion to the existence of the infectious agent, additional factors, such as the agent, host, and/or the environment are all generally imperative for infection and disease to occur. But who would have concluded that one of the most menacing viral infections would result from a mammal? The Nipah Virus Infection (NiV) is a known emerging infection, targeting the public health

Currently, one of the major problems in the world is the rapid change of our climate. Years of research and studies have linked climate change to the spreading and occurrence of many infectious diseases. Vectors and pathogens that were not able to spread to certain countries before because temperatures were too low for them to survive in are now being able to habituate these parts of the world because of how much warmer our planet is becoming. This is concerning to us because infectious diseases can increase death rates. Therefore, if our planet continues to get warmer, the more infectious diseases will spread, and the more humans will die. This research paper attempts to provide a better understanding on how diseases are spreading more

Climate change increases the possibility of extreme weather events which in turn makes disease transmission more frequent in poor, developing countries. The weather event known as El Nino has been determined to be one of the leading environmental factors that influences disease. El Nino is a band of warmer than average water, which

The Infectious Diseases Society of America (IDSA) has recently noted several model antibiotic-resistant bacteria strains with redesigned capabilities in pathogenesis, transmission and resistance. These several strains, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species, have been given the acronym-based title of the ESKAPE Pathogens. These strains of bacteria compromise one of the biggest threats faced by physicians today not because of the infectious and devastating illnesses they lead to, but because of their ability to resist antibiotics in the healthcare setting. Failure for industries, academia and government to cooperate and develop research/development operations has left healthcare providers one-step behind in the fight against these new brands of infectious diseases. A lack of research/development operations has left the healthcare industry with antiquated antibiotics no longer capable of targeting and eradicating these microorganisms in human systems.

(WHO 2015) It is now generally acknowledged that the global climate is changing as the earth becomes warmer, in particular due to the burning of fossil fuels. Human health may be impacted by shifting the geographic range and seasonality of infectious diseases, possibly increasing vector borne disease rates, disturbance of food-producing ecosystems, and increasing the frequency of extreme weather events such as droughts, cyclones, floods and bush

Zoonotic diseases is a serious and major concern to human health. What is a zoonosis? Zoonoses are diseases that are caused by pathogens that can infect different animals that has the ability to pass to humans. Zoonotic pathogens also destroy biodiversity in fragile wildlife. They cause many effects to humans in many different ways. Zoonosis are very important to study because scientists await a challenge on developing vaccines on a developing cure on human aids. Zoontic diseases are dangerous because it can spread by mosquitos, and ticks.

Is the food were eating safe? What exactly is going into my body? Will I get sick or die from eating or drinking this? These are questions millions of Americans are puzzled with everyday. Approximately 325,000 Americans are fossilized and 5,000 die from food-borne disease. Some people think that whatever they are eating and putting into their bodies is safe, for me, that’s not true.

However, disease on the epidemic scale did not appear till certain conditions existed, conditions created namely by the Agricultural Revolution. As communities became more sedentary and developed a more stable means of food production through the domestication of animals and irrigation processes, populations were able to increase at exponential rates, one of the fundamental prerequisites for an epidemic outbreak. An increased population translated into closer living conditions, less sanitary means of waste disposal due to sheer volume, and typically, poorer nutrition, making people more susceptible to a breakdown of the immune system. A higher population, in comparison to that of their hunting and gathering predecessors, meant a greater chance for contracting an illness. Equally important, the Agricultural Revolution demanded the domestication of animals. In living in close proximity to cattle, hogs, and other useful livestock, a phenomenon known as species cross-over took place. This species cross-over refers to the mutation of diseases typically found in livestock to a new form that seeks out a human host. The most classic and devastating example is small pox, a highly fatal disease that causes sores to form on the body and known in cattle as cowpox (Ponting, 225-226). This, coupled with irrigation, providing a host for water-born diseases like malaria and schistosomiasis, sheds a bit of light on the magnitude of the influence of the Agricultural

Globalization aided in impacting human health by population mobility. The source of epidemics throughout history can be traced back to human migration (Saker). The effects of these epidemics have changed whole societies. International efforts to prevent the spreading of infections from one country to another have been focused on. Early diseases that spread between Asia and Europe included the bubonic plague, influenzas of various types, and other similar contagious diseases. The world is more interdependent and connected than ever in the era of globalization. This is because inexpensive and efficient transportation allows access to almost everywhere and the increase of global trade of agricultural products brought an increasing number of people into contact with animal disease. Trade routes had long been established between Europe and Asia along which diseases were unintentionally transmitted. The management of malaria is a global role (Carter). Global institutions support the

“The rodents spread the plague from China to Europe and it hit Britain in 1348.”(Bates, Claire) So if the world is so populated more people will be homeless, and the disease could spread easier wiping out millions. The black death was also spread by people getting bites from infected rats, the disease travels through the body into the lungs, and when the person coughs or sneezes, the disease is transmitted into the air and can infect people who breath in that same air. So if the world becomes too over populated and there aren’t enough houses people will be living on the streets where disease could spread easier and faster just like the black death. “Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air.”(DIRECT…) So if everyone if coughing and sneezing then anyone who breathes in that contaminated air could get the disease. “Last year, it called dengue the “most rapidly spreading mosquito-borne viral disease” in the world—faster than West Nile virus or malaria.”(The deadly…) If this disease was to break out when the world is overpopulated a disease could take out almost half the entire human race.There are hundreds of diseases that can be spread by animals, some examples are all types of Influenza, Bubonic Plague, zoonotic diseases, HIV/AIDS, Ebola, and Polio. One disease is the Zika virus, it is spread by mosquito bites who bite women and when if the infected women gets pregnant the Zika virus transfers the virus to the child, once the child is born the child could be born with a fatal brain defect. When the world becomes more populated more people could get bit with more mosquitos and get the Zika virus and a whole new generation of kids could be born with a brain

Global warming may increase the risk of some infectious diseases, like malaria, dengue fever, yellow fever, and encephalitis. These diseases are spread by mosquitoes and other insects, and could become more common if a rise in temperature allows those insects to live farther north. Also, the increase in rainfall that is likely to occur with an increase in global temperature would serve to help increase the reproduction of the vectors. In February 1999, Britain's Institute of Animal Health linked outbreaks of the lethal horse fever virus in Africa to the El Nino phenomenon. The warming and increase in rainfall in Africa caused by El Nino led to many more horses being bitten by infected vectors. The scientists said their research shows this pattern is likely to happen with other vector-borne diseases when global warming occurs. Increased temperatures could also reduce the gestation periods of disease vectors, which could aid the breeding of strains resistant to pesticides. Scientists also hypothesize that algae
