(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".

Section 1 Malaria General Information Malaria is a common infectious disease found mainly in the tropics but in rare circumstances can be found in temperate areas. Depending on the circumstances malaria can be either life threatening cause serious illness. It is caused by parasites of the Plasmodium species(in text reference). These parasites are carried by mosquitoes which become infected after biting someone who has malaria. Malaria is then passed on to others when the infected mosquito bites another

dengue virus type 2 (DENV-2), dengue virus type 3 (DENV-3) and dengue virus type 4 (DENV-4). 1. 8. 1. Taxonomy There are three genera in the Flaviviridae family (formerly known as group B arboviruses) namely Flavivirus, Pestivirus and Hepacivirus. The dengue virus is a member of the genus Flavivirus which consists of 55 identified virus species (ICTVdB, 2006). The word Flavi is a derivation from the Latin “flavus” which means “yellow” and the type species of the genus is a yellow fever virus (YFV). The
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

What is yellow fever? Yellow Fever is a virus that is found in tropical areas of both Africa and South America (Monath 160). It is found in 47 countries in both those areas (WHO 1). It is generally called “Yellow Fever” because of its medical symptoms such as the yellowing of skin and eyes that affect many people (WHO 1). While Yellow Fever had existed in the 1690s, the first serious known case of Yellow Fever is in the breakout in Philadelphia in America of the year 1793 where black refugees

between it and congenital malformations seen in newborns and other brain involved ailments which have been compared with the demyelization as it is seen in Multiple Sclerosis. Discovery 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
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
Introduction What is dengue fever? Dengue fever is caused from a transfer of misquotes bite to human that contains the Aedes aegypti virus. The disease affects people that live in countries such as South Asia Pacific, Caribbean and South America. There has been a major outbreak in India due to large demand to live urban area. One major problem these countries have is their drainage system when rain falls. When it rains, it leave a large body of water that become unclean which is a target site
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
DEFINITION (1) Cirrhosis can be simply defined as diffuse fibrosis associated with parenchymal nodules. It involves the whole liver rather than a small part even though on occasion the fibrosis may be more severe in one or other lobe. Fibrosis results partially from collapse of the new fibre formation and is usually regarded as a consequence of liver-cell necrosis. The nodules of a cirrhotic liver are the surviving parenchyma. But they are strutually altered. They vary greatly in size and appearance
