Disease and Pathology
West Nile virus is an emerging infectious disease because it keeps re-emerging; showing an increase in incidence and it has spread to different geographic areas by modern transportation. This virus was first identified in 1937 in Uganda, Africa and it has existed in Africa and the Middle East for decades, if not centuries. But in 1999, it landed in Queens, New York, via an unknown route. The infection then proceeded to move across the country and since then has spread to 48 states, Canada, Mexico, and many other countries.
Encephalitis is a severe symptom and the most common symptom in hospitalized West Nile Virus patients, affecting 50% to 84% of patients; it manifests with behavioral or personality changes such as irritability, confusion, or disorientation that can evolve into stupor and even a coma, with mental status changes persisting for up to several weeks. Although very serious symptoms rarely occur in infected people, about 20% of infected people do have milder symptoms, which include, fever, headache, body aches, nausea, vomiting and sometimes swollen lymph glands. The majority (80%) of infected people have no symptoms. Symptoms of W...

- The West Nile Virus **Let it be known that I am writing this account in the hope that it may someday benefit future generations, although I hope for their sake that the world has by then tamed the West Nile Virus. First and foremost, mosquitoes are the human beings' enemy in the battle against West Nile Virus. This is not to say that we as humans should declare an all out war on the creatures, but rather that people need to be especially aware during the months of August and September of avoiding those areas (such as those near standing water) which attract mosquitoes....

- Introduction: West Nile Virus, belong to family Flaviridae is a virus transferred by mosquitoes which was first identified in Uganda in 1937 (2). It was perceived as public health threat with epidemics of fever and encephalitis in the Middle East in the 1950’s (3). Since then there has been many sporadic outbreak in Asia, Europe, Africa, and Middle East (3). The first human cases of WNV disease in the Western Hemisphere were detected in New York City in 1999(1 ). By the end of 2005, virus has a very wide established sustained transmission geographical foci from central Canada to southern Argentina making it the most widely distributed Arbovirus in the world....

- This first discovered virus was identified in 1937 in Uganda in eastern Africa named West Nile Virus. West Nile virus is a single stranded RNA virus that lies within the family of flavivrus, which is part of the Japanese encephalitis antigenic complex of viruses. It is found in both tropical and temperate regions. It is known to infect vertebrates and certain insects. The most common route in which it infects humans is through the bite of an infected mosquito. West Nile Virus hit the United States the summer of 1999 in New York.... [tags: Disease]

- Introduction: West Nile virus and Zika virus belong to Arbovirus group which are usually transmitted by mosquito, ticks or some other vectors. The growing concern regarding West Nile virus is not unexpected as people has seen the worst consequences of Zika virus. But as an Epidemiologist, any conclusion should be made in a systemic way base on previous data and background knowledge about the investigation. Being the same group member does not always make them equal deleterious. As we all know that not all the hepatitis virus causes hepatocellular carcinoma, few of them are very mild that they persist few days without leaving any long-term effect....

- Emerging Infectious Diseases are diseases that are new, re-emerging, or drug-resistant and the incidence in humans has increased within the past two decades or whose incidence threatens to increase in the near future. Factors that contribute to the emergence of new infectious diseases are microbial adaptation and change, widespread usage of antibiotics, economic development and land use, international travel and commerce, human demographics and behavior, and technology and industry. One emerging infectious disease that has been re-emerging is the West Nile Virus.... [tags: Disease/Disorders]

- History of the West Nile Virus Abstract West Nile virus (WNV) is a virus that is transmitted by mosquitoes. It has been found in humans, birds, and other animals, typically in Africa, Eastern Europe, and the Middle East. In 1999, WNV was detected in the United States for the first time, and since then it has spread across the U.S. According to the U.S. Centers for Disease Control and Prevention (CDC), over 15,000 people in the U.S. have tested positive for the WNV infection since 1999, including over 500 deaths....

- Risks and Effects of West Nile 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.... [tags: Biology Medical Biomedical Disease]

- 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....

It was first found to cause meningitis and encephalitis during an outbreak amongst elderly people in Israel in 1957. It was first found to infect other vertebrates (equine species) in France in the early 1960's. It did not cross over to the US until 1999 and has now spread to 44 states.

- The Impact of West Nile Virus on Humans (or Why We Should Worry) West Nile virus can infect humans, but there are more drastic ways that it affects our lives. The virus normally lives in birds and is transmitted among them and other animals by mosquitoes. There is no other definite method of transmission, and people do not have to worry about contracting the virus through contact with infected humans or animals. Hundreds of species of birds and many mammals, including several endangered species, are vulnerable to the virus.... [tags: Biology Medical Biomedical Disease]
