Emerging diseases have been a threat to humanity for centuries. The many technological advances have allowed scientists to discover the ways, in which these diseases can be controlled and, in some cases, eradicated. By definition, emerging diseases are those diseases that have emerged on specific geographical locations where they were not recorded previously, or diseases that already exist on a specific geographical area but are rapidly spreading throughout a population (Jorge R. Ray, 2015). There are different ways of how these diseases can be spread out. Some examples of this are inappropriate interactions between humans and animals, environmental changes, and interactions with people that have travel internationally. These are some of the …show more content…
Insects also are famous for transmitting very dangerous viruses. Dengue is an example of a disease that, sometimes, can be deadly and is transmitted by a specific type of mosquito (the Aedes mosquito) (Jorge R. Rey, 2015). There are two types of Dengue. There is the mild Dengue, which is not deadly, and the hemorrhagic Dengue, which can be deadly if not treated promptly and appropriately. Some of the symptoms of the hemorrhagic Dengue are fever, sore throat, headaches, vomiting, and abdominal pain (Centers for Disease Control and Prevention, 2015). In 2015, there have been a big number of Dengue cases registered in China, Malaysia, Singapore, The Philippines, Australia, and some islands in the Pacific Ocean (World Health Organization, 2015). One of the ways to prevent being infected with this virus is identifying the specific mosquito that transmits this virus and searching around for places where such mosquito could be incubating its offspring. This virus is very common in Latin America, so growing up in Venezuela; I had the opportunity to learn how to identify this mosquito by recognizing a body feature that this mosquito has. This type of mosquito has small white stripes around its body. In some countries, people called the “white leg mosquito”. Another way to prevent Dengue is by checking around people’s houses for stagnant water, which is the perfect place for mosquitos to incubate their offspring. By not having stagnant waters around houses, people can be safe from this disease. Therefore, based on these two examples of animal-contact diseases, it is clear to see that people should be careful of what animals or insects they interact with and how they interact with them as
In addition, overwhelming historical evidence suggests that the greatest rates of morbidity and death from infection are associated with the introduction of new diseases from one region of the world to another by processes associated with civilized transport of goods at speeds and over distances outside the range of movements common to hunting and gathering groups.

In the United States today, many aspects of health are very segregated. This form of separation is referred to as silos. Animal, human, and environmental health are separated into these silos. Experts in these fields rarely work together or collaborate. The majority of research, funding, and resources are separated in to the three disciplines. The solution to this issue is the concept of “One Health”. One Health acknowledges the connectivity of all aspects of health. By working together, it is possible to detect outbreaks of disease earlier and save many more lives. One Health has made a dramatic influence on infectious disease prevention, detection, and treatment. Although there has been some advancements, there is still much
You wouldn’t think the carrier of this disease would come from a little mosquito bite but it does.
Mosquitoes, fever and even death may be some of the things that come to mind when we're asked to think about West Nile Virus. Many of us would consider mosquitoes a small trade-off for what the summertime provides, but what if there were more at risk than a bump above your skin and an itch? In a not so distant past West Nile Virus ascended into news broadcasts all throughout the country and alarming it's residents. Today however, that all seems to be an afterthought. The intentions today are to cover the first found cases of West Nile Virus, the symptoms of West Nile Virus, and finally West Nile Virus' impact on the United States. Through the research here, the hope is that we can all have a better understanding of how West Nile Virus works.

The Ebola virus was discovered in 1976. It has four strains, each from a different geographic area, but all give their victims the same painful, often lethal symptoms.
The seventh major case of Endangered Specie. Specific species of mosquito play host to one phase of various disease organisms they are the cause of major diseases that lead to human compilation. Most people don’t find it wrong to wipe the entire mosquito species in other to prevent human diseases such as sleeping sick, malaria, and human
The human population has a high susceptibility to the contraction of new diseases and outbreaks of these diseases are of high risk. Diseases in recent times that have broken out into the human population are the H7N9 flu strain and SARS. Despite the risk, outbreaks like H7N9 and SARS have been controlled due to epidemiology and other disease control methods. Outbreaks of disease are not uncommon to the human population as they move to new areas around the world with foreign diseases that the native residents would have developed a resistance to.
Throughout history many different diseases have infected the world. Such diseases consist of measles, mumps, malaria, typhus and yellow fever. Many of these diseases are caused by different things and originated in different countries.
Diseases are everywhere in this world, in humans, animals, and even plants. It's a part of life but it's up to us to develop new technology and new techniques to take care of diseases. We should all help each other to take care of ourselves and live a better life and avoid catastrophes.
In the 1960s, doctors in the United States predicted that infectious diseases were in decline. US surgeon Dr. William H. Stewart told the nation that it had already seen most of the frontiers in the field of contagious disease. Epidemiology seemed destined to become a scientific backwater (Karlen 1995, 3). Although people thought that this particular field was gradually dying, it wasn’t. A lot more of it was destined to come. By the late 1980s, it became clear that people’s initial belief of infectious diseases declining needed to be qualified, as a host of new diseases emerged to infect human beings (Smallman & Brown, 2011).With the current trends, the epidemics and pandemics we have faced have created a very chaotic and unreliable future for mankind. As of today, it has really been difficult to prevent global epidemics and pandemics. Although the cases may be different from one state to another, the challenges we all face are all interconnected in this globalized world.
The author painted a gloomy picture that the author painted of a world ravaged with disease with no solution in sight. The author illustrated using various examples how globalization has made the disease outbreaks spread at lightning speed. The author also discussed new diseases as well as old familiar diseases that were eradicated and have made a comeback. However, the author has shown that there is light at the end of the tunnel. There is political goodwill among developed countries mitigating the global health challenge. The world is wealthier than before hence it can afford to fund health interventions. Scientists have also developed cheaper health intervention mechanisms while health economists have developed cheap health intervention plans.

The occurrence of infectious disease and epidemics has speckled the history of humanity since the first civilization established itself. Considering that a large population can help to foster infectious diseases, and humans share almost 300 communicable agents with animals, the outbreak of epidemics is inextricably intertwined with revol...
Some, such as the establishment of surveillance systems, dissemination of guidelines, implementation of research findings, or development of effective public health programs, are examples of such tools by which public health has dealt with the burden of disease for decades. However, we still continue to face new challenges, not the least, the threat to our environment through climate change, emerging and re-emerging infections such as Zika, Ebola, SARS, Elizabethkingia, the ever present threat of an influenza pandemic, high risk behaviors such as substance abuse – spiraling heroin abuse of recent and Neglected Tropical Diseases (Lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminths and trachoma.) that caused health and life expectancy loss with consequential reduced ability to
