West Nile Virus has emerged in recent years throughout the temporate zones of Europe and North America. Causing a variety of conditions in its hosts, the most serious manifestation of WN virus infection is fatal encephalitis (inflammation of the brain) in humans and horses, and many birds.
History
While many forms of encephalitis exist, West Nile Virus was first isolated and identified in the West Nile District of Uganda in 1937. The virus, which was seemingly isolated to North Eastern Africa, became recognized as a cause of severe human meningoencephalitis (inflammation of the spinal cord and brain) in elderly patients during an outbreak in Israel in 1957. In addition to the human victims of this disease, the virus was found Egypt and France during 1960s to have fatal effects within horses. While this disease spread through Northern African and Southern Europe, 1999 marked the first appearance of West Nile Virus in North America, with encephalitis reported in both humans and horses.
West Nile in the United States
The West Nile Virus first came to the U.S. public's attention following an outbreak in New York in August 1999 where eight patients has contracted ecephalitis from the virus. In the following four years the virus spread to almost all 48 contiguous states. In the United States cases were initially infrequent until 2002, when a massive outbreak occurred in the Mississippi River basin during August and September. As it has spread through the country, nearly 8,500 people have been diagnosed with the virus, which has lead to 189 deaths. The emergence of the new disease has been followed closely by the media and the government. Many areas that have experienced significant outbreaks of the Virus have occured have implem...

* Step Three:Help Your Community Control the Disease.
While it is relatively easy to control what happens around your home, it takes community effort to help curb West Nile on a city wide level. Help authories by reporting any dead birds that you see, see if your city/town has a mosquito control program that you can help with, or even get together with your neighborhood to clean the local park and remove mosquito breeding areas in public spaces.
West Nile Virus is nothing to be afraid of, but it must be taken seriously. The process by which these goals are met are simple, but require you to take proactive measures in your day to day life.
In the article “When Mosquitoes Were Killers in America” by Lauren Tarshis, She makes the statement “Yet mosquitoes are far more than a nuisance.” What she means is that mosquitoes aren't a little bug that just sucks a little blood and can be annoying, but instead it uses all that and more. Mosquitoes have killed millions upon millions of people by spreading disease like malaria. An example of how she supports this claim is in the article, she says “ In this way, bite by itchy bite, 212 million people are infected with malaria every year” (Tarshis 13). And that is only a year with bug spray, shots, and all the other things that help stop mosquitoes. So when the U.S. government tried to save people from these murders little insects. So they
This virus is similar to Ebola, because it started in the same place. Lab workers in Germany, in 1967, contracted the new virus while working with African Green Monkeys, which had the virus. The virus is described as a hemorrhagic fever. It has a fatality rate up to 90% and spreads through human to human contact. The first symptoms can be as simple as a fever and a headache, then can progress to organ failure, and fatal internal bleeding.
The Asian Tiger Mosquito commonly thrives in residential areas with shade and anything that can hold water. Cans, buckets, flower vases and other water holding containers (like tires), are suitable breeding sites for this invasive species. The male of this species feeds on nectar from plants, whereas the females feed and depend on blood to help them with the development of their eggs. Females may also feed on nectar also....
The medical field is a vast land of beauty, but with great beauty comes immense horror. There are many deadly viruses and diseases found in the medical field. In the novel, The Hot Zone by Richard Preston, the author discusses the many deadly viruses found in the field. The viruses are widespread due to the errors that occur when the viruses are in the presence of human beings. The effects of the errors performed by the human race include a decrease in population and wildlife.
Chester M. Southam, MD, was an American virologist who worked on curing cancer. “Studies had shown that a pathogen called the Russian spring-summer encephalitis virus could eradicate tumors in mice. Because that virus was considered too dangerous for people, Southam searched for something milder, settling on the newly discovered West Nile virus.” He had already spent some time in Africa injecting an assortment of viruses including mumps, dengue, West Nile, and Semliki Forest virus in severely ill cancer patients. The West Nile Virus usually
Chikungunya virus (CHIKV) is a member of the family Togaviridae and genus Alphavirus that have been associated with large sporadic epidemics (Schwartz & Albert, 2010) (Suhrbier, Jaffar-Bandjee, & Gasque, 2012). CHIKV is transmitted to humans by infected mosquitos of the genus Aedes, Aedes aegypti and Aedes albopticus (Torres, et al., 2015). This virus was first identified in 1952 in East Africa and later caused large outbreaks in tropical Asia and Africa (Sissoko, et al., 2009). Chikungunya fever is a re-emerging disease; appearing again in an outbreak in India, 2005, after being silent approximately 32 years (Mohan, Kiran, Manohar, & Kumar, 2010). International travels helps in the introduction of CHIK to different areas. In late 2013, the
An animal infected with CWD will have neural loss, astrogliosis, which is an abnormal increase in the number of astrocytes in the brain, and spongiform lesions (Abrams et al., 2011). The infected particles are spread all throughout the body including the brain, spinal cord, eyes, peripheral nerves, and lymphoreticular tissues (Belay et al., 2004). Most of the infection, however, is located in the Central Nervous System.

BSE has been seen to progress very slowly in relation to other diseases, however is very contagious and fatal for not only cattle, but humans as well. While many diseases that are transmittable from animals to humans will affect the young or older humans, the median age of those infected with Mad Cow Disease is 26 (2). BSE has been linked to a fatal brain disease in humans referred to as variant Creutzfeldt-Jakob disease or vCJD. Eating meat from an infected cow is what many presume to be the cause of vCJD in humans (3). Symptoms include movement deficits, memory disturbances and cognitive impairments, all of which lead to an eventual death. The majority of the BSE cases reported have primarily been outside of the United States; from 2003 to 2012 23 cases were identified in North America, 4 of which in the United States (1). This may seem to be a small amount, however because it is believed to be transmitted through the meat of cattle it can be extremely dangerous and be shipped all over the United States before it is ever identified.
