acute phase of hepatitis
Hepatitis C. The incubation period for hepatitis C virus (HCV) is 15-150 days, with symptoms developing anywhere from 5-12 weeks after exposure. During acute HCV infection, symptoms may appear similar to those of HBV infection.In up to 80% of cases, however, patients are asymptomatic and do not develop icterus.epatitis C. The incubation period for hepatitis C virus (HCV) is 15-150 days, with symptoms developing anywhere from 5-12 weeks after exposure. During acute HCV infection, symptoms may appear similar to those of HBV infection. 1 The first phase of disease, during the first 6 months after a person becomes infected, is called acute hepatitis B infection. 2  During this phase, many people show no symptoms at all. 3  Among those who do have symptoms, the illness is usually mild and most people don't recognize that they have liver disease.uring the acute phase (first 6 months after infection) most persons have no symptoms or might experience a mild illness. Symptoms of acute HBV infection, when present, may include: 1  Jaundice (yellowing of the skin and eyes). 2  Dark-colored urine, light-colored stools. 3  Fatigue. 4  Abdominal pain. 5  Loss of appetite. 6  Nausea. 1 In 90% of persons who become infected as adults with hepatitis B, the immune system successfully fights off the infection during the acute phase -- the virus is cleared from the body within 6 months, the liver heals completely, and the person becomes immune to hepatitis B infection for the rest of their life.uring the acute phase (first 6 months after infection) most persons have no symptoms or might experience a mild illness. Symptoms of acute HBV infection, when present, may include: 1  Jaundice (yellowing of the skin and eyes). 2  Dark-colored urine, light-colored stools. 3  Fatigue. 4  Abdominal pain. 5  Loss of appetite. 6  Nausea. In the United States, viral hepatitis is most commonly caused by hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV). These 3 viruses can all result in acute disease with symptoms of nausea, abdominal pain, fatigue, malaise, and jaundice. Additionally, HBV and HCV can lead to chronic infection.BV causes more than 4 million cases of acute hepatitis per year throughout the world, and it is estimated that approximately 350 million people are chronically infected with the virus. HBV leads to 1 million deaths annually as a result of viral hepatitis–induced liver disease. Hepatitis A (formerly known as infectious hepatitis) is an acute infectious disease of the liver caused by the hepatitis A virus (HAV).Many cases have few or no symptoms, especially in the young. The time between infection and symptoms, in those who develop them, is between two and six weeks.bout 40% of all acute viral hepatitis is caused by HAV. Infected individuals are infectious prior to onset of symptoms, roughly 10 days following infection. The virus is resistant to detergent, acid (pH 1), solvents (e.g., ether, chloroform), drying, and temperatures up to 60°C. The incubation period of hepatitis E virus (HEV) is 2-9 weeks (average, 45 days). HEV usually causes an acute self-limited disease similar to HASV infection. Fulminant disease does occur in about 10% of cases. In women who are pregnant, HEV infection has a case-fatality rate of 15-20%.epatitis C. The incubation period for hepatitis C virus (HCV) is 15-150 days, with symptoms developing anywhere from 5-12 weeks after exposure. During acute HCV infection, symptoms may appear similar to those of HBV infection. Chronic infection with HBV and HDV may lead to fulminant acute hepatitis and severe chronic active hepatitis with progression to cirrhosis. Over the long term, as many as 70-80% of these patients have evidence of chronic liver disease with cirrhosis, compared with only 15-30% of patients with chronic HBV alone.epatitis C. The incubation period for hepatitis C virus (HCV) is 15-150 days, with symptoms developing anywhere from 5-12 weeks after exposure. During acute HCV infection, symptoms may appear similar to those of HBV infection. Hepatitis B is a contagious liver infection caused by the hepatitis B virus (HBV). The natural course of hepatitis B disease is different from one person to another.1  The first phase of disease, during the first 6 months after a person becomes infected, is called acute hepatitis B infection.uring the acute phase (first 6 months after infection) most persons have no symptoms or might experience a mild illness. Symptoms of acute HBV infection, when present, may include: 1  Jaundice (yellowing of the skin and eyes). 2  Dark-colored urine, light-colored stools. 3  Fatigue. 4  Abdominal pain. 5  Loss of appetite. 6  Nausea. The incubation period for hepatitis B virus (HBV) is 30-180 days (average, approximately 75 days). Patients then enter the prodromal or preicteric phase, characterized by the gradual onset of anorexia, malaise, and fatigue.epatitis C. The incubation period for hepatitis C virus (HCV) is 15-150 days, with symptoms developing anywhere from 5-12 weeks after exposure. During acute HCV infection, symptoms may appear similar to those of HBV infection. Viral hepatitis causes fever, nausea, liver enlargement and tenderness, jaundice, pale stools and loss of appetite. Fifty percent of cases are due to hepatitis A, whereas hepatitis B is considered a sexually transmitted disease (contact with contaminated body fluids).It is important to note that hepatitis B can be transmitted in health care facilities where exposure to sharp instruments with contaminated blood is a possibility.f we are fortunate enough to catch a case of hepatitis early in the acute phase (icterus), intravenous vitamin C works exceedingly well to hasten recovery, cutting sick time in hepatitis A to two weeks and in type B to less than a month.
