Mosquitoes, fever and even death may be some of the things that come to mind when we're asked to think about West Nile Virus. Many of us would consider mosquitoes a small trade-off for what the summertime provides, but what if there were more at risk than a bump above your skin and an itch? In a not so distant past West Nile Virus ascended into news broadcasts all throughout the country and alarming it's residents. Today however, that all seems to be an afterthought. The intentions today are to cover the first found cases of West Nile Virus, the symptoms of West Nile Virus, and finally West Nile Virus' impact on the United States. Through the research here, the hope is that we can all have a better understanding of how West Nile Virus works. 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. According to (James Sejvar 2003): The patient presented in the setting of a large epidemiologic study of yellow fever virus; however, inoculations of mice with the patient's serum resulted in the isolation of a virus with physical and pathologic properties similar to those of two flaviviruses, St. Louis encephalitis virus and Japanese B encephalitis virus, and sharing immunological relationships with these viruses. (para. 3) West Nile Virus has been determined to be a flavivirus. Flavivirus has been defined as, "a type of arbovirus that causes a wide range of diseases in humans,including yellow fever, dengue, and West Nile fever. It is spread by ticks or mosquitoes". (flavi... ... middle of paper ... ...ounters with West Nile were accounted. Between the travels of Uganda where we were first introduced to West Nile, to the outbreaks in Israel, and eventually on our own shore in New York. We covered the symptoms of West Nile and explained how scary the thought that anywhere from 70%-80% of infected do not show any symptoms. Through that research we discussed how many different types of West Nile we could contract and how each played vastly different roles to the illness. Finally, we approached what the response and impact was for the United States. We covered the outbreaks of 2002 and 2012, we dealt with high concentrated areas(i.e. Texas, Louisiana, Illinois), along with preventive measures put in place for research and funding. Please remember that we still need increased funding and awareness to the public to help further the cause against West Nile Virus.
You woke up a week ago feeling odd. You were not sure what was wrong, but your body was full of aches, you felt hot to the touch, and you kept vomiting. Your mother told you to lay down and rest, hoping it was just a cold. After a few days, you began to feel better, well enough that you wanted to return to the river to watch the trade ships come in. Now, unfortunately, your symptoms have come back with a vengeance – your fever is back along with intense abdominal pain, your mouth is bleeding without being wounded, and every time you vomit, it appears black in color. Also, when you look in the mirror, your skin has changed from the sun-kissed color you have always been to a dull yellow hue. The doctor comes in to examine you; he makes many “tsk tsk” noises and hurries out of the room with a cloth over his face. The doctor mumbles to your mother that he believes you have Yellow Jack and there is nothing more he can do, you are going to die. Your mother weeps uncontrollably yet you cannot react because another horrendous pain in your head has doubled you over. Soon, as you stop shaking and begin to relax, the sounds of the doctor and your mother become white noise and your surroundings begin to dull until you prove the doctor right; another person fell victim to the infectious Yellow Fever virus.
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. The viruses are spread in many different ways in the novel, but all are due to human mistakes.
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
West Nile virus (WNV) is a single-stranded flavivirus mostly present in the eastern hemisphere that can affect humans, birds, horses, mosquitoes, and other domestic and wild animals. It has plagued the world since it was first identified in West Nile province of Uganda in 1937 (Sally Murray). Since this time, according to the South Carolina Department of Health and Environmental Control (SCDHEC), the disease has been spotted in “Africa … Europe, the Middle East, West and Central Asia … the United States … Canada,” and now Central America. Despite its discovery in the 1930’s, the western hemisphere went without the disease until 1999; the first documented case of WNV in the United States was in New York (Watson). West Nile Virus presents a near never-ending problem for the United States because of its similarities to other arboviral disease and its ability to transmit quickly.
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.
It's very helpful when doctors, especially ones as well educated as Dr. Sergio Cortes, explain imminent health threats in plain, everyday language that everyone can easily understand. Getting information out to the public regarding the Zika virus is vital; the article Find Out More About Zika Virus With Sergio Cortes, from his personal blog, gives people the tools they need to lessen their chances of contracting the virus. Since Zika is now definitely linked to microcephaly, a birth defect affecting infant’s development, it is imperative that pregnant women avoid contracting the Zika virus. The virus is not contagious; people cannot catch it from another person who has the virus, however, when a mosquito that stings a person who has the Zika
In certain places, such as North America, yellow fever has been totally eliminated and the government suggests vaccination for the disease if a citizen is leaving the country. There are many symptoms of yellow fever, and they vary depending on the severity of the disease. Some of the symptoms are basically normal and would not lead the sufferer to believe that something was seriously wrong. The first symptoms, fever, headache, nausea, and backache are common and appear soon after a patient has contracted this disease, but as stated they are also the same symptoms of the common cold or flu.... ... middle of paper ...
According to the World Health Organization (2014) “Ebola first took place in 1976 in 2 simultaneous outbreaks, one in Nzara, Sudan.., in Yambuku, Democratic Republic of Congo. [and the] latter occurred in a village near the Ebola River, from which the disease takes its name”. The disease has also started spreading through countries such as Guinea, Sierra Leone, and Liberia (which are West African countries). The United States of America had their first case of Ebola on September 30, 2014, when a man traveling back from Liberia was diagnosed with the disease in Dallas, Texas (CDC 2014). The man did not show symptoms until he reached the United States.
West Nile or WNV is a virus that is most commonly spread to people by mosquito bites. The first cases were recognized in and the Middle East, India, Australia, Africa, some parts of Asia, and Europe. It was not known to be in North America till around 1999. People can get infected with West Nile virus by getting bit by an infected mosquito. The mosquitoes become infected when they feed on infected birds. An infected mosquito can give the virus to humans and animals.
Zika virus has been gaining notoriety due to the recent Rio Olympics. It is not a new disease, in fact, it has been around for a long time. The first recorded case of Zika virus infection was in Uganda in 1947. Previous research and press coverage on the disease highlighted microcephaly in babies as the main detrimental effect of Zika virus. The speaker aimed to show the other less known facts and effects of Zika virus during the seminar.
Although viral cases of WNV usually work themselves out, the more severe cases require hospitalization.1, 2 A serology test is most successful in diagnosing when taken between the eighth and twenty-first day after the appearance of symptoms. Blood tested for IgM antibodies before or after this period will most likely be inconclusive to the presence of the virus.2 Since there has been no overly effective anti-viral treatment discovered to date, hospitalization often is for patient support and monitoring. Pain medication and intravenous fluids are administered as needed for recovery.
The West Nile Virus is a powerful disease that has made a big impact on Americans. Phillip Margulies states in his book that the West Nile Virus is a vector-borne virus, which means the virus comes from a bloodsucking insect or in this case a mosquito. The virus travels in the body of an infected bird or insect and gets into humans through mosquito bites (Margulies,41). The humans and animals that are infected can become very ill or just experience a
The West Nile Virus is a disease which is transmitted to birds from infected mosquitos. The birds are used as reservoir hosts that can pass on the disease to other birds and to humans, as well as other mammals (Lim). It is a single-stranded RNA virus of the family Flaviviridae, and the genus Flavivirus and it is responsible for the deaths of many birds and humans in both the United States and the Eastern Hemisphere (Peterson). The West Nile virus was originally found in the West Nile District of Uganda and only found in the Eastern Hemisphere, until the year 1999 when the disease appeared in New York (Peterson). Most of the West Nile epidemics
Zika virus or ZIKV, which is an Arbovirus of the flavivirus genus belonging to the flaviviridae family, is a mosquito-borne virus that was first identified in 1947 by scientists who were conducting some research in the Zika Forest, located in Uganda. The Zika forest with its luscious foliage of around “135 species
Dengue is the most common arboviral (arthropod-transmitted) disease and it also position as the most important mosquito-borne viral disease in the world. Approximately 2.5 billion people living in tropical and sub-tropical regions are at a great risk of dengue infection, which is almost equal to about two-fifths of the human population (Gubler & Clark, 1995; WHO, 2009). There is an estimated 50-100 million infections occurring globally in each year, with 500,000 cases requiring hospitalization and causing 24,000 deaths (Halstead, 1988; WHO, 1997). Furthermore, the increasing populations in tropical and sub-tropical regions, making dengue as a global threat to public health (UNEP 2009; Holden, 2009).
