What is there to Know about WNV and WNE? West Nile Virus (WNV) is an arbovirus that causes West Nile Encephalitis (WNE), an inflammation of the brain. The virus was first found in an Ugandan woman, and spread throughout all areas of the world, from Europe to Oceania. WNV is virus carried by mosquitoes and birds. Other organisms are the secondary carriers of the virus. The first outbreak resulted in victims of WNE. Since then the U.S has been alert and cautious about the virus for public health. The virus is known to affect animals as well. Up to now there is no special treatment or vaccine for WNV and its symptoms. However, there are ways to preclude you from getting the virus. Though the chances of getting WNV and a fatal case are slim, the symptoms aren’t worth risking. West Nile Encephalitis is a brain inflammation that is caused by mosquitoes. WNE is new to the U.S.A and broke out less than a decade ago in one of the states. So far there aren’t any vaccines for WNV, but there are methods of prevention. Up to this day, WNE isn’t common; however, it is a brutal enemy to those who are infected. The first outbreak of WNE was in New York City in 1999. Four deaths occurred in 1999 due to WNE (Illinois Department of Public Health). Studies show that there was less involvement with their cortex, thalamus, and cerebellum. Their microglial modules that carried histiocytes and lymphocytes were dispersed and they also developed leptomeningitis. Two years later, in the autumn of 2001, the infection spread to Iowa and Missouri. There were 54 infected people in Illinois and a death in 2003 (Illinois Department of Public Health). By now, WNE has spread to the West Coast. Researchers aren’t sure how WNV or WNE was introduced to the U.S.A.... ... middle of paper ... ...tious of areas that are reported to have infected mosquitoes. If anyone is going outside during the times of day or the places where they are prone to get infected, being cautious and careful can prevent a severe case of WNE.

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.
An animal infected with CWD will have neural loss, astrogliosis, which is an abnormal increase in the number of astrocytes in the brain, and spongiform lesions (Abrams et al., 2011). The infected particles are spread all throughout the body including the brain, spinal cord, eyes, peripheral nerves, and lymphoreticular tissues (Belay et al., 2004). Most of the infection, however, is located in the Central Nervous System.
The article ‘Zika Virus and Microcephaly’ has broadly discussed the Zika virus. Zika virus has spread uncontrollably through South and Central America. There has been many cases reported of infants getting affected by the by the disease while they are in their mother’s womb; and also their has been increase in reports of infants born with microcephaly. Microcephaly is a congenital condition in which the child’s brain is not developed completely and their head is abnormally small.
Rift Valley Fever is a viral zoonotic disease that is arthropod-borne.1, 2, 3, 4 This viral disease primarily affects domestic animals but has the ability to affect humans.1, 3, 4 The severity of the disease can range from mild to severe and can be potentially fatal.1 An epidemic in the animal population, also known as an epizootic, could result in increased economic loss as the disease leads to livestock death and spontaneous abortion among pregnant animals .1, 2, 3, 4 A reduction in trade could also result contributing to further economic loss.1, 2, 3, 4 The virus which causes Rift Valley Fever is in the family Bunyaviridae and the genus Phlebovirus.1, 2, 3, 4, 5
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...
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.
It is believed that this virus has been in hiding since ancient times. The lack of knowledge about it’s natural history and reservoirs keeps researchers seeking out the mysterious virus that has no treatment or cure. Based on the available evidence and comparisons of similar viruses, researchers believed the virus to be animal-borne and that the host animal is native to Africa. Their attempts have been unsuccessful, and the source of the virus or where it circulates in between outbreaks is unknown.
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.
The first symptom my uncle experienced was a rash that covered his whole body, followed by flu-like symptoms. I recall my aunt saying she 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 the diagnosis, my mom returned to all three of the emergency room physicians with a copy of my dad’s
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.
There is a chance that Zika virus could become established in North American wildlife because of the rapid increase in the two invasive species of mosquito, Aedes aegypti and Aedes albopictus, which are mainly accountable for the spread of zika virus in the Americas. However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects. Also, A pregnant woman can pass Zika to her fetus during pregnancy or around the time of birth. Additionally, a person with Zika can pass it to his or her sex partners. People who have traveled to or live in places with Zika should be encouraged to protect themselves by preventing mosquito bites and sexual transmission of Zika.
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.
West Nile Virus (WNV) is an enveloped RNA virus that is transmitted from mosquitoes. The first case in North America was discovered in 1999 and it has been discovered that both birds and mosquitoes are carriers of this neuropathogen. Upon biting an infected bird, the mosquito is then infected. When the infected mosquito bites the human, the virus is transferred. Since West Nile Virus’ method of pathogenicity is zoonotic, it is not known to be transferrable from person to person.2 This flavivirus has been known to differentiate into the less serious West Nile Fever and the more severe West Nile Meningitis and West Nile Encephalitis.1
The Zika virus is a mosquito-borne infection which studies say is the cause of microcephaly. This condition leads to babies being born with very small heads and incomplete brain development. The Zika virus is spread from one person to another by a mosquito called Aedes aegypti. Some people who are infected have symptoms such a mild fever, joint pain, and a rash. The Zika virus was first discovered in 1947 in Uganda, Africa. The virus hadn't been spread to the Americas until May of 2015 when scientists diagnosed the first case of Zika in Brazil. Since then, Brazil found more than 4,700 newborn babies were diagnosed with microcephaly. Many scientists believe getting a Zika infection during pregnancy might cause the microcephaly. Some South American
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.
