Flaviviridae

Hepatitis is inflammation of the liver. There are currently five known viruses that cause can hepatitis (Microbiology, 10e). The hepatitis C virus (HCV) is transmitted through contact with the blood of an infected person; however, it is now more commonly spread among IV drug users that share needles. Healthcare workers are also at risk for contracting HCV, but with standard precautions, the risk is low. “Prior to 1992, some people acquired the HCV infection from transfusions of blood or blood products

How many cases of West Nile Virus were reported in your state based on the epidemiology data? In year 2013, CDC (Centers for Disease Control and Prevention) get report of 2605 cases as regards to noticeable arboviral disease, comprising those caused through 2469 cases of WNV (West Nile Virus), 85 cases of LACV, 22 cases of JCV, 8 cases of EEEV, and 15 cases of POWV, and cases of few other diseases. These cases were stated from 26 percent (830) among the 3141 nations of U.S., no cases were stated

Hepatitis C virus (HCV) is a small (~55 to 65 nm), spherical enveloped virus that can cause major illness. Hepatitis C was discovered after the intense investigations between 1982 and 1988 in Chiron corporation. Michael Houghton discovered the non-A and non-B hepatitis by using the molecular approach. Hepatitis C affects liver caused by the hepatitis virus; the virus can cause acute and chronic hepatitis infection ranging from a mild illness to severity, lifelong illness. Mostly patients are affected

Most people would say that there are two different versions of viruses. One version of viruses infects people's computers and completely ruins them (which personally happens to me way to often, by the way), but the other version of viruses is a lot more deadly. These viruses affect all sorts of living things and could cause them to get very sick. Viruses replicate themselves inside an organism's living cells and they then spread to other organisms. Viruses usually spread in a similar fashion to how

WEST NILE ENCEPHALITIS Serah Hinga MICROBIOLGY Instructor: Mrs. April Champa Date: 10/17/2016 West Nile Encephalitis is a West Nile Virus that causes inflammation of the brain. The viral family’s name is flaviviridae and genera flavivirus (Tortora. Funke. Case, 2010, p 376). The flavivirus genome consists of positive RNA single strand. However, the virus has acquired several mutations and research is ongoing (Tortora, Funke, Case, 2010 p 223). West Nile virus is an arthropod-borne

HCV infections are a major global health burden. HCV is a member of the Flaviviridae family where it forms the genus Hepacivirus. These viruses are enveloped and have a positive-sense single-stranded RNA genome. Initial attempts to infect cultured cell lines with HCV contained in serum of infected patients resulted in no virus replication or if any, very low and variable (4). In 2005, All 3 research teams, Charles Rice, Frank Chisari and Ralf Bartenschlager team, separately developed their cell culture

outbreak during 1827-1828.From hereon terms like Denga and Dinga were often used and hence was derived the present day nomenclature of Dengue.Dengue term was first used in 1828 during an epidemic in Cuba. Dengue virus(50nm) belongs to family Flaviviridae. The mature dengue virion consists of a positive (+)single-stranded RNA genome surrounded by an icosahedral or isometric nucleocapsid about 30 nm in diameter. This nucleocapsid is covered by a lipid envelope. The complete

West Nile fever is caused by the West Nile Virus. Describe the emergence of novel disease in the Western hemisphere. Provide some examples of sources on infection for novel disease, including the mode of transmission for WNV. Why is this a concern? West Nile Virus (WNV) has caused a global pathogen with a significant morbidity and mortality. It was first discovered in the West Nile District of Uganda in 1937 (Roehrig, 2013). It was first seen in the United States in 1999 and has been “estimated

Calender University of South Alabama The Zika Virus in Brazil Global health issues continue to embark on many challenges in the world. These challenges are perpetuated with the decrease in quality of care, morbidity, and mortality for patients. Global health is an exclusively multidisciplinary problem, effecting all society and requiring a comprehensions and collaboration between

Virus Overview      The virus was first thought about in 1883 when A. Mayer was seeking to find the cause of the tobacco mosaic disease. Though he was unable to see them with the microscopy of his day, he postulated that a small agent caused the disease. D. Ivanowsky, later tried tests as well and also concluded that it was a disease caused by something smaller than they could see. The virus was first found and discovered in 1935 by Wendell Stanly. He was able to
