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. Many more people have likely been infected with WNV, but have experienced mild or no symptoms.
What is the history of the West Nile virus? West Nile virus is an emerging infectious disease that can cause encephalitis (inflammation of brain tissue) and or meningitis (swelling of the tissue that encloses the brain and spinal cord). West Nile virus is a newly emergent virus of the family Flaviviridae, found in both tropical and temperate regions. Its group is classified in Group IV (gram(+) single stranded, RNA). Its genus is Flavivirus. It?s commonly found in Africa, West Asia, the Middle East, and more recently; North America. It may result to serious illnesses if not reported to the hospital in time. Knowing its history, how it?s transmitted, symptoms, treatment, and prevention will probably keep one from getting it.
In 1937, West Nile virus was first discovered in a feverish woman in the West Nile district of Uganda in Central Africa. The virus 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 the early 1960?s, Eastern Equine Encephalitis (affecting horses) was first found in Egypt and France (We...

... people may need to go to the hospital where they can receive supportive treatment including intravenous fluids, help with breathing, and nursing care.
To help prevent WNV: Empty plastic wading pools at least once a week or store in a position that water will drain. Make sure your backyard pool is maintained properly.
It is though that once a person has recovered from WNV, they are immune for life to future infections with WNV. This immunity may decrease over time or with health conditions that compromise the immune system. As long as people get older or immune system is weak you may end up getting it again. This is very important because just to know if people can get it again when there immunity isn?t work very good. The U.S. government and its citizens should care

because there is no vaccine to cure it or it can mutate and get even harder to fight it off.
Although nurses do not wield the power of doctors in hospital settings, they are still able to effectively compensate for a doctor’s deficits in a variety of ways to assure patient recovery. Nurses meet a patient’s physical needs, which assures comfort and dignity Nurses explain and translate unfamiliar procedures and treatments to patients which makes the patient a partner in his own care and aids in patient compliance. Nurses communicate patient symptoms and concerns to physicians so treatment can be altered if necessary and most importantly, nurses provide emotional support to patients in distress.
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
Almost no one on Earth has any immunity at all to this virus, which makes ordinary vaccines useless against it. The sudden spread of the virus into Europe foreshadows an epidemic development that could be worldwide. Ultimately, there is no way to protect ourselves against epidemics. They will keep disappearing and coming back in new forms.
The nursing discipline embodies a whole range of skills and abilities that are aimed at maximizing one’s wellness by minimizing harm. As one of the most trusted professions, we literally are some’s last hope and last chance to thrive in life; however, in some cases we may be the last person they see on earth. Many individuals dream of slipping away in a peaceful death, but many others leave this world abruptly at unexpected times. I feel that is a crucial part to pay attention to individuals during their most critical and even for some their last moments and that is why I have peaked an interest in the critical care field. It is hard to care for someone who many others have given up on and how critical care nurses go above and beyond the call
There is no vaccine to protect against it and, in the most severe cases, no cure. The population of Phoenix has grown by ten per cent in the past deca...
Rift Valley Fever was first reported around 1910, but was not identified until a Kenyan sheep farm was investigated after an epidemic in 1931.1, 2, 3, 5 The common name of the virus was derived from the area which it was identified, the Rift Valley of Kenya.1 A majority of the reported outbreaks of Rift Valley Fever have been contained to Sub-Saharan and Northern Africa.1, 3, 4 The most notable animal outbreak of Rift Valley Fever occurred in Kenya from 1950 to 1951.3, 4 This outbreak resulted in the death of approximately 100,000 sheep.3, 4 An outbreak in Egypt resulted in approximately 600 human deaths and a significant number of animal deaths in 1977.3, 4 In September of 2000, the first cases of Rift Valley Fever outside of Africa were confirmed in Saudi Arabia and later in Yemen.1, 2, 3, 4 Since the confirmation of the disease outside of Africa, Rift Valley Fever has been identified as a priority disease that has the potential to emerge geographically.2
West Nile Virus gets its name from its birthplace in the West Nile District. According to (Gubler, Duane, Marfin, Anthony & Petersen, Lyle, 2003) it was in 1937 that Uganda had its first isolated case of West Nile Virus (para. 4). This first case was found in the blood of a woman determined to be febrile.
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.
Ebola Zaire was identified in 1976 in Northern Zaire and was the first documented appearance of the virus.
At this point one is put on a ventilator. A ventilator is a machine which maintains the circulation of blood, oxygen and nutrients to organs around the body. Putting a patient on life support is very costly to the family of the patient and even the hospital. Once a person is brain dead, they are said to be legally dead and the time and date of death is reflected on their death certificate. In South Africa it is not stated that doctors can withdraw life support once a patient is declared brain dead due to ethical debates (Fleischer, 2003).
Nobody is perfect. We all make mistakes. Some of the best lessons in life are learned from making a mistake. But in the healthcare world making mistakes means losing lives. This has started to happen so frequently there has been a term coined – Failure to Rescue or FTR. Failure to rescue is a situation in which a patient was starting to deteriorate and it wasn’t noticed or it wasn’t properly addressed and the patient dies. The idea is that doctors or nurses could’ve had the opportunity to save the life of the patient but because of a variety of reasons, didn’t. This paper discusses the concept of FTR, describes ways to prevent it from happening; especially in relation to strokes or cerebrovascular accidents, and discusses the nursing implications involved in all of these factors.
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.
...at is required, give him/her something to eat or drink and get medical help. Always remain calm, help the person to remain calm (as much as possible), and stay with the person until medical help arrives.
Naturally you'd hope and expect the hospital to have enough resources to facilitate the return to health, or to prolong their lives,
Immunisation is the only effective way of protection for children against these diseases because children’s immune systems are defenceless ageist them because they are not fully developed yet, and once infected in most cases there is no cure or at least a very low chance of one. Minor side effects of immunisation, like redness at the injection site, or occasionally a mild fever, which can easily be reduced with a paracetamol. But why would any one rather let your child be able to catch and spread these deadly diseases then get them immunised because of these rare and very minor risks.
