Introduction For my final paper, I will do research on Hepatitis C for recognition targeted towards technical publications as JAMA, New England Journal Of Medicine etc. Hepatitis C (HCV) causes inflammation of the liver and can cause liver damage leading to cirrhosis. Occasionally, liver cancer may develop. First called non-A non-B hepatitis, hepatitis C was discovered in the early 1970 s, but it wasnt until 1989 that testing for specific antibodies to the virus began. Each year, 15, 000 Americans contract hepatitis C, which is a more frequent cause of chronic liver disease than hepatitis B. While at least half of the patients with acute hepatitis C become chronic, some estimate the rate as high as 80%.
Who is at risk People at risk include anyone who has had a blood transfusion, health care workers (which we intend to be in the near future), I. V. (intravenous) drug users, and hemodialysis patients. How is HCV transmitted The virus is found in blood, semen, vaginal secretions and saliva. It may be transmitted via transfusion, sex, sharing razors, needles, toothbrushes, nail files or even a barbers scissors. All people with HCV are potentially infectious.

As many as 3. 5 million people are believed to be carriers which means that they have the virus in their system and whether they have symptoms or not, they can infect others. Unlike hepatitis A and B, previous infection does not produce immunity. Is there a vaccine for hepatitis C There is no vaccine for HCV and vaccines of other forms of hepatitis do not provide immunity against hepatitis C. What are the symptoms Most people infected with HCV do not have symptoms. Even if they have normal liver function tests, they are called carriers.
The virus is in their blood and can cause damage to the liver Carriers can transmit the virus to others. If symptoms are present, they are usually mild and flu-like: nausea, fatigue, loss of appetite, fever, headaches, and abdominal pain. Most do not have jaundice (yellowing of the eyes), however, it can occur along with dark urine. Is there a cure Few people are able to clear the virus from their blood, which is necessary, to be completely recovered.
Over half of the cases reported each year become chronic, which means liver enzyme levels remain elevated for at least six months after the acute infection. What does chronic hepatitis mean Chronic HCV indicates a gradual progression of the disease over 10-40 years. A liver biopsy can identify the type and degree and is the best method of determining the severity of the disease. Patients with Chronic HCV have increased risk for developing primary liver cancer. It is believed that 20% of these patients will develop cirrhosis of the liver (damage to the liver), and another 25% will develop liver failure after which death may occur. Is there a treatment Treatment for chronic hepatitis C is limited.
Currently, the only FDA approved treatment is interferon alpha-2 b. The treatment must be given by injection and it may have a number of side-effects. Interferon may also interfere with the production of white blood cells and platelets by depressing the bone marrow. Bibliography Murray, P. R.

The Essay on Hepatitis B Virus Hbv Protein Symptoms
The Hepatitis B Virus (HBV) HBV is a mostly double-stranded DNA virus in the Hepadnaviridae family. HBV causes hepatitis in human and related virus in this family cause hepatitis in ducks, ground squirrels and woodchucks. The HBV genome has four genes: pol, env, pre-core and X that respectively encode the viral DNA-polymerase, envelope protein, pre-core protein (which is processed to viral capsid) ...
Chronic Hepatitis. Disease-a-Month, Masters in Medicine. 39 (2): 53-126. February 1993. This monograph presents an overview of chronic hepatitis. Topics include a classification of chronic hepatitis based on histologic manifestations: I will use this to understand further the causes of the major disorder, its management and treatment.
