Essay on 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. 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

The incidence is highest in late summer and early autumn, until the first hard frost does away with the mosquito population for that year. Birds and other animals (such as horses) are the usual reservoir for the infection, and they are involved in its dissemination. Initial viral symptoms may give way to high fever and neck stiffness (meningeal signs). However, as with most forms of encephalitis, it is the confusion and depressed levels of consciousness (stupor) that mark the infection as being of the brain (encephalitis) and not just the meninges. West Nile Virus is an acute central nervous disease (McCance & Huether, 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).

The Iowa Department of Public Health has confirmed a rare case of disease caused by the Jamestown Canyon virus. In addition, there are two cases has been reported to the Iowa’s Health Department about West Nile Virus, which is also an illness spread by mosquitoes, along with Jamestown Canyon virus. According to the author, people who are infected by these two viruses will experience: “fever, headache, and flulike illness.” Luckily, however, “the patients who had Jamestown Canyon virus and West Nile virus are slowly recovering.”

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.

Encephalitis is a neurological disorder that results in the inflammation of the brain and sometimes the meninges. It is usually due to a viral infection. Most often arboviruses cause encephalitis, by transference via mosquitos to humans and animals. When bitten by an infected mosquito the virus moves from the mosquito into the person’s blood, it then reaches the brain and spinal cord, it multiplies within the central nervous system thus inflaming and damaging nerve cells, this interferes with signals from the brain to the rest of the body. The herpes simplex virus type one can commonly cause encephalitis. HIV has also been noted as an increasing cause of encephalitis. Viral infections like: mumps, chicken pox and measles can also cause encephalitis, but rarely.

Case Description- A 3 month-old Boer cross buck kid was confirmed to have died from an infection of Eastern Equine Encephalitis in a rural county of North Florida. Caprine Arthritis Encephalitis and Rabies were included in the list of deferential diagnoses as possible causes of neurologic symptoms that could occur in adolescent caprine.1,5 PCR analysis of fresh brain tissue preformed at Department of Health in Tampa, Florida (via the Bronson Animal Disease Diagnostic Laboratory in Kissimmee, Florida) showed positive for Eastern Equine Encephalitis, then positive by virus isolation. The sample was negative for West Nile Virus, and the fluorescent antibody test for Rabies was negative.

In New Mexico, we started off with 47 West Nile cases in the year 2012, in the year 2013 there were 38 cases, and in the year 2014 there 24 cases were identified (CDC, n.d.). With these CDC statistics, it can be said that both Epidemiologists and Public Health Professionals are doing an adequate job of educating and preventing further West Nile cases. There are also tools such as the CDC website that give information on how to prevent people from catching West Nile. No new information has been learned about the virus and viral transmission. However, a few small amount of cases have shown human infection which consisted of the

What is the West Nile Virus? It is an illness distinguished by headaches, muscle soreness, a fever, and more. The illness’ affects vary depending on the person and the symptoms, though very few can sometimes be critical. It is diagnosed specifically as the West Nile Virus by those special symptoms. Many wonder about certain treatments for the virus and whether or not there are vaccinations for it. It can be identified by a few common effects of most flus, but what are the details that differentiates the West Nile Virus with the others? The diversity between the West Nile and flus include details such as transmission, symptoms, and treatment. What is the illness and how is it transmitted?

Mosquitoes pass malaria to humans through their salivary glands. Once the parasites have entered the blood stream, they go to the liver. In the liver they mature and undergo reproduction, forming merozoites. These merozoites enter the blood stream and inject themselves into red blood cells. Once inside the blood cells, they reproduce rapidly and within forty-eight to seventy-two hours, the blood cell bursts, releasing hemoglobin into the blood stream. It is the destruction of these blood cells and the hemoglobin released into the blood stream that actually causes most of the symptoms.

Since 1999, the West Nile virus spread geographically throughout North America, except for two states, Alaska and Hawaii, which till this day does not have occurrences of WNV statistically shown by the CDC (2014). The introduction of the WNV resulted in the United States centers of Disease Control and Prevention (CDC) to initiate what was known as the National West Nile Virus Surveillance System for 2000. These objectives include:

West Niles Virus is a virus that is transmitted from mosquito to aves and mammals via infected mosquito bites and is prevalent within most of the Continental United States. It is reported that, “40 states have recorded cases of West Nile Virus” (Jolly par. 4). The complications with mosquito bites is problematic because of the spread of disease is due to the infected mosquitos and there is a need to implement a control systems to decreased swarms of mosquitos, in particular within Maricopa County. This cause is important because I have recently been diagnosed as having West Niles Virus. There is no current vaccination for humans against the West Niles Virus, the only way to reduce chances of contracting the virus would be through prevention

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.

Some of the viruses that cause encephalitis are arboviruses, cytomegalovirus, poliovirus, herpes zoster, and herpes simplex type 1. West Nile virus has been a big

A number of studies have supported the theory that the virus had originally occurred in animals previous to human infections.5 The MERs-CoV virus is a type of coronavirus that has been known for infecting both birds and many species of mammals. These types of infections are commonly referred to as zoonotic diseases because the pathogens are able to be transferred from animals to humans. Zoonosis can happen with or without a vector in order to spread the infection. Although the exact origin of the MERs-CoV infections is unknown, there has been convincing research performed that has found related types of coronaviruses in bats and camels. According to the Center for Disease Control and Prevention, the coronavirus is found in multiple species and can cause respiratory illness and gastrointestinal upset.
