Essay On West Nile Virus

West Nile Virus is known as an arthropod-born virus, or an arbovirus, and are transmitted and sustained within blood feeding arthropods, such as the mosquito. The disease, while having no apparent effect on the host, is then transmitted as the mosquito takes a blood meal. As the source of infection, the mosquito or other blood feeding arthropod is known as a primary vector. However, because the life cycle of the mosquito is reletively short an additional host is needed to maintain the life cycle of the virus.

West Nile Virus has many effects on the human body as well as on the bodies of other animals. West Nile is an extremely dangerous virus that attacks the Central Nervous System. It can cause inflammation of tissues in and around the brain and spinal cord. In humans, there are three levels of West Nile Virus, which have different symptoms. Humans can also get specific diseases such as encephalitis from West Nile Virus. West Nile Virus also affects animals. Wild birds and horses are the most susceptible to the virus and most animal deaths occur in these species. Dogs and cats are much less likely to contract the disease. The only way for a human or animal to get the disease is to be bitten by a mosquito

West Nile Virus (WNV) was originally detected from a woman in Uganda in 1937. WNV first appeared in the United States in 1999 in New York which was the first incident in the Western Hemisphere. WNV is a mosquito-borne virus (arbovirus). It is in the flavivirus family. WNV is a neurotropic virus. WNV is a member of the Japanese encephalitis virus. Severe encephalitis outbreaks in humans have been escalating. The means by which the virus gains access to the brain (also known as neuroinvasion) seems inadequately understood. Suggestions of the hypothesis of WNV leans towards the concept of blood-brain barrier disruption and retrograde axonal transport (Suen et al., 2014)

The West Nile Virus is a virus that people can get from an infected mosquito bite. This virus disappeared and no one heard much of many people getting the virus for about 20 years. In the 1990´s there was a big comeback on the rise for the West Nile Virus. That also consisted of the infected bugs slowly but surely making their way to America from Africa, the Native country to this virus (Phillip).

Infectious epidemics and pandemics have happened all through mankind's history. “They remain the prime cause of death worldwide and will not be conquered during our lifetimes.” The flu of 1918 was one of the deadliest epidemics in history. “It infected an estimated 500 million people worldwide–about one-third of the planet’s population at the time–and killed an estimated 20 million to 50 million victims. More than 25 percent of the U.S. population became sick, and some 675,000 Americans died during the pandemic.” No one knew how the virus spread, there were no antibiotics to fight it, and no flu shots to prevent it. In the final year of World War I, it struck terror in the hearts of people all across Europe and left more death in its wake than the combined military actions of the combatants. “It killed more Americans in a few months than World War I, World War II, the Korean War, and the

Lower return crops such as corn, wheat, cotton and rice will bear the brunt of this whereas the higher return crops such as nuts, citrus and vine crops will be least affected (Kowalski, 2015).

The main point of the press release is to notify the public that the West Nile Virus has surfaced and is active. One of the sub-points is to inform the public of the current case and the number of cases over the years of people who have been infected with the West Nile Virus. Another sub-point is to give the description and signs of the West Nile Virus. Another sub-point is to notify the public where the West Nile Virus is coming from. Another sub-point what is causing the mosquitoes to breed and how to prevent the breeding of the mosquitoes to notify the public that there are two types of West Nile Virus. The West Nile encephalitis and the West Nile poliomyelitis are the two viruses the press release also notified the public of the signs and symptoms of the west Nile virus. What to do and who to contact once bitten the press release gives a statistic of number of cases from 2002 to 2011 (2012). The press release also notifies the public who is at the highest risk to becoming ill with this type of virus. The press release also gives other website to seek out more information regarding the West Nile Virus.

This disease can kill someone and mosquitoes are the ones that carry it. Lots and lots of people were getting it, but George said that if we don’t think about it that maybe, just maybe, nobody in our family will get it. We know that there is always a chance, but we can always hope for the best.

In conclusion, the West Nile Virus is not that dangerous to our society today. Even if someone does get bitten by a mosquito that is carrying the virus, only about 20 percent of people will get the disease. Even if they do get the disease it is usually just a little sickness that you will overcome. The most dangerous part of this disease is when it affects the brain, but this is a 1 percent chance. There has been various incidents in the U.S. There has been about 44,000 cases of West Nile virus have been reported in the United States since

What is West Nile Fever? West Nile fever also known as West Nile virus is a mosquito borne disease transferred from mosquito to person. Encephalitis is a disease that West nile virus can cause. What encephalitis does is it causes inflammation of the brain which in some cases can be fatal. The west Nile virus wasn’t discovered until 1937 in Africa. The disease didn’t make its way into the United States until 1999. The Virus is most common during the summer months (July- September) which is when mosquitos the carrier of the disease are most active. But in some states it is at risk all year round. Most people who are bitten and infected even receive the virus.

The Yellow Fever virus came from Central or East Africa. With transmission between primates and humans, the virus has been spread from there to West Africa. The virus was probably brought to the Americas with the slave trade ships from 1492 after the first European exploration. The first case of Yellow fever was recorded in Mexico by Spanish colonists in 1648. Consequently, the virus started to spread also in North America. In Philadelphia in 1793, more than the 9% of the population die. The American government had to escape from the city that was the temporary capital. One of the most famous outbreaks happen in Europe in Barcelona in 1821.How explains the article "The 'plague' of Barcelona. Yellow Fever epidemic of 1821", the outbreak of

The Ebola Virus is an extremely deadly virus found in Africa. There have been multiple outbreaks across Africa and one in the United States. The Ebola virus basically causes uncontrollable bleeding externally and internally. Then your organs become liquefied. This usually results in death(www.encyclopedia.com). The following report contains info on the characteristics and history of the Ebola Virus.

Another short story of the article tells about the deputy director of the Centers for Disease Control and Prevention, Stephen Ostroff, warning that there will be malaria in America in the next decade. Moreover, the Surgeon General, David Satcher, says that America is in danger by the presence of disease in Africa. Satcher describes Africa as hot, wet, unsanitary and impoverished. At the end of the story, he states that a global system of disease surveillance and public health should be established. Goldberg’s 1999 article “Microbes on the Move” was published in response to the first case of exotic West Nile virus in New York, and it is applicable today because most people in America or other countries still do not feel threatened by the presence of viruses in Africa.

The Ebola Haemorrahagic Fever, or Ebola for short, was first recognized as a virus in 1967. The first breakout that caused the Ebola virus to be recognized was in Zaire with 318 people infected and 280 killed. There are five subtypes of the Ebola virus, but only four of them affect humans. There are the Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast and the Ebola-Bundibugyo. The fifth one, the Ebola-Reston, only affects nonhuman primates. The Ebola-Zaire was recognized on August 26, 1976 with a 44 year old schoolteacher as the first reported case. The Ebola-Sudan virus was also recognized in 1976 and was thought to be that same as Ebola-Zaire and it is thought to have broken out in a cotton factory in the Sudan. The Ebola-Ivory Coast was

Severe Acute respiratory syndrome (SARS) is a respiratory illness that had recently been reported in Asia, North America, and Europe. SARS was first reported is Asia in February of 2003, over the next few months it spread to more than a dozen countries. By late July 2003, no new cases were being reported and the global outbreak was declared over by the World Health Organization. During this time period 8,098 people worldwide became infected with SARS and out of these 774 died. In the United States a total of 192 SARS cases had been reported, including 159 suspect and 33 probable cases. Of the probable only 8 had laboratory evidence of SARS-CoV infection. Luckily, no SARS relate deaths occurred in the US.
