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
Stopping The West Nile Virus In 2002 the West Nile Virus was found in 38 states and killed 188 people before the year was over. The West Nile Virus has existed in Africa for thousands of years infecting wildlife and people, but it has been affecting people more than ever these past few decades. The West Nile virus is transmitted into humans and wildlife through mosquito bites. In the past vaccines and pesticides have been used to control these types of issues, but this virus isn’t as simple. In order
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
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
The epidemiology of both dengue and West Nile Virus (WNV) are based on mosquito patterns and their interaction with human. Dengue has plagued nearly every continent and continues to be a major public health problem. WNV, on the other hand, is a relatively new human public health problem, especially in the US. It might be possible to model control efforts found effective against the globally distributed dengue for control of West Nile Virus right here in the US. I was in high school when WNV hit my
disease transfer are horizontal and vertical, in which horizontal transmission passes on a disease or virus from individual to individual, whereas vertical transmission passes on a disease from parent to offspring. The ability of any infectious disease to invade a population or transfer to new areas is one of the most important concerns regarding wildlife ecology (van den Driessche). The West Nile Virus is a disease which is transmitted to birds from infected mosquitos. The birds are used as reservoir
their audience and their purpose draw on that information to create strong thesis. For example, if the student knows that his audiences are young children, that his purpose is to get children informed about how to protect themselves from the West Nile virus in a language that would be easy for them to understand so they can get the full message about the topic, furthermore, he wants to prove that by applying DEET repellent and wearing long sleeve shirts and pants kids will be protected against mosquito
heightened in concentrated populations like New York. Some of the alleged pollution problems are water contamination, excessive noise and the presence of smog. Several diseases have spread throughout the city in recent years including the flu, West Nile Virus and meningitis. Another biological contaminant that has been found in NYC recently is Anthrax. This substance being sent through the postal system and other crimes endanger the well being of the citizens of this famous city. Anything from a car
Herpesviral encephalitis Herpesviral encephalitis is encephalitis due to herpes simplex virus. Herpes simplex encephalitis is a viral infection of the human central nervous system. It is estimated to affect at least 1 in 500,000 individuals per century and some studies suggest an incidence rate of 5.9 cases per 100,000 live births. The majority of cases of herpes encephalitis are caused by herpes simplex virus-1, the same virus that causes cold sores. 57% of American adults are infected with HSV-1, which is
Fredonia There is a little remnant of a town in south central North Dakota named Fredonia. The locals there tell of a time 40 or so years ago when there were 400 people living in town but if you go there today you will be lucky to find 50 hardy souls still clinging to the land of their ancestors. Most of the people that remain were alive at the end of the last world war but there are a few still in their prime, unable to break their bond with the land in favor of brighter prospects in Fargo or
Dear Goodwell Nzou, I am writing this letter to contend in contradiction of your article that was published on 5th August, 2015 in The New York Times titled, “In Zimbabwe, We don’t cry for lions”, in which you disapproved of the American Doctor being portrayed as the villain. Your article speaks about how the lions are at fault and how the lions are a ‘menace’ to villagers like you, but the real problem is not the lions but some of the people only. Your article on The New York Times did get a lot
thought it was West Nile, but it took her a month to convince the doctors to run the test. Coincidentally, the first symptom my dad had was the same rash and flu-like symptoms, so my mom immediately suspected West Nile. Over a period of two weeks my dad saw three different emergency room physicians who all said it was not West Nile, even though they had not tested him for it. Eventually our family doctor was convinced to run the test and seven days later we had the diagnosis of West Nile Virus. After getting
pregnant women with the Zika virus in Puerto Rico and other U.S. territories between Jan. 1, 2016 and April 25, 2017” (Harris par. 4). Many people have been identified as carrying Zika and this is worrisome as Zika causes birth defects – like microcephaly – in young children and raises the average risk of pregnancy up by eight percent. Both the expecting parents and the newborns should avoid being exposed to the risks coming with mosquitoes transmitting the Zika virus. Also, studies from the American
Currently, America is faced with a new issue called the Zika Virus. Like malaria, this virus is carried by a vector, the mosquito, and is directly transmitted to a human. The population that is at a high risk of being infected with this disease is pregnant women. Yet there have been current cases that say Zika can be transmitted through sexual contact. This is currently a health policy issue because there is the lack of funding towards the Zika virus. Also, lawmakers need to address this issue in order to
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
DNA vaccines have been researched, and scientists are trying to find ways to put them into use and cure diseases in humans and animals. Vaccines activate the protective immunity that is an effect natural infection, without having to become sick with an infection (Paul Offit, 2014). Vaccines reduced the probability of people today to get diseases like the measles, and other major infectious diseases (Anonymous, 2011). Vaccines are not always safe, and also lots of vaccines are not always as effective
1. 8. Dengue Virus The causative agent of the dengue disease is the dengue virus (DENV), a group of four flaviviruses that are closely related but antigenically distinct. They are hypothesised to have evolved independently from ancestral sylvatic viruses between 100-1,500 years ago (Wang et al., 2000). The four groups are known as serotypes and denoted as dengue virus type 1 (DENV-1), dengue virus type 2 (DENV-2), dengue virus type 3 (DENV-3) and dengue virus type 4 (DENV-4). 1. 8. 1. Taxonomy There
Criminal Activity Blighted homes have become a breeding ground for criminal mischief and drug activity. Drugs are being sold, hidden, and prepared in the blighted properties across the city. Criminals use the abandoned homes as a hideaway from local law enforcement and the FBI. The sharing of needles by drug users can spread diseases like HIV/AIDS and even hepatitis to the community. A local resident of the 7th ward of New Orleans says that, "It's a problem because me and a neighbor, we get out
How can Animals kill us? There are many diseases people catch from animals and insects known as Zoonose. Whether they are food, pet or just naturally flying. People are getting sick off of animals directly, indirectly or from the environment. For centuries people always had a close relationship with animals. Whether they are house pet, farm animals or food on a plate. People and animals go hand and hand. Animals and insects are important to nature just as humans. For many years people have discovered
I believe mosquitos should be extinct. Mosquitos don't have any purpose on this world. They’re only destructive and create deadly viruses worldwide. Zika, Malaria, Dengue fever, and West Nile are only a few of the dangerous illness that come from mosquitos. I believe mosquitos should be extinct. These creatures may look cute or welcoming to some, but mosquitos have the definition to be one of the most deadly insects. The Aedes Aegypti and Aedes Albopictus mosquitoes cause destruction in their
