Hepatitis A 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.

Hepatitis A 1 Hepatitis A is a viral liver disease that can cause mild to severe illness. 2  The hepatitis A virus is transmitted through ingestion of contaminated food and water or through direct contact with an infectious person.he incubation period of hepatitis A is usually 14–28 days. Symptoms of hepatitis A range from mild to severe, and can include fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, dark-coloured urine and jaundice (a yellowing of the skin and whites of the eyes).

Hepatitis A Antibody, IgM Hepatitis A virus is a picornavirus, and antibody is made to capsid proteins. Fecal excretion of HAV peaks before symptoms develop. If hepatitis A antibody is IgM, the hepatitis A infection is probably acute. IgM antibody develops within a week of symptom onset, peaks in three months, and is usually gone after six months. Hepatitis A antibody of IgG type is indicative of old infection, is found in almost 50% of adults, and is not usually clinically relevant. Many cases of hepatitis A are subclinical, particularly in children.

History The incubation period of hepatitis A virus (HAV) is 2-7 weeks (average, 28 days). Clinical symptoms then develop, often with a presentation similar to that of gastroenteritis or a viral respiratory infection.he 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%.

Overview Acute hepatitis B infection lasts less than six months. Your immune system likely can clear acute hepatitis B from your body, and you should recover completely within a few months. Most people who get hepatitis B as adults have an acute infection, but it can lead to chronic infection. Chronic hepatitis B infection lasts six months or longer. It lingers because your immune system can't fight off the infection. Chronic hepatitis B infection may last a lifetime, possibly leading to serious illnesses such as cirrhosis and liver cancer.

- Hepatitis B accounts for 15-30 per cent of the cases of acute hepatitis seen in India (20-27), while HCV is an infrequent cause of acute icteric hepatitis (28,29) though it is responsible for most of the cases of post-transfusion hepatitis.

History Hepatitis A. The incubation period of hepatitis A virus (HAV) is 2-7 weeks (average, 28 days). Clinical symptoms then develop, often with a presentation similar to that of gastroenteritis or a viral respiratory infection.he 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.

Hepatitis (Viral Hepatitis, A, B, C, D, E, G) 1 All hepatitis viruses can cause acute hepatitis. 2  Viral hepatitis types B and C can cause chronic hepatitis. 3  Symptoms of acute viral hepatitis include fatigue, flu-like symptoms, dark urine, light-colored stools, fever, and jaundice; however, acute viral hepatitis may occur with minimal symptoms that go unrecognized.

Which is worse- Hepatitis A, B, or C? Acute hepatitis lasts under six months, while chronic hepatitis lasts longer. Most liver damage is caused by 3 hepatitis viruses, called hepatitis A, B and C. However, hepatitis can also be caused by alcohol and some other toxins and infections, as well as from our own autoimmune process (the body attacks itself).

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.

What Happens What Happens. Most people who have hepatitis B have an acute (short-term) infection. 1  They start to feel better after 2 to 3 weeks and recover completely after 4 to 8 weeks. 2  They develop antibodies to hepatitis B. These antibodies provide lifelong protection against future infection.

Hepatitis C (Hep C, HCV) In the acute stage, more than two thirds of people who become infected have no symptoms. For those who develop symptoms (2 to 26 weeks after infection), the symptoms last for 2 to 12 weeks. The symptoms are: 1  Upper abdominal pain, especially on the right.  Dark urine.

Hepatitis Hepatitis is inflammation of the liver tissue. Some people have no symptoms whereas others develop yellow discoloration of the skin and whites of the eyes, poor appetite, vomiting, tiredness, abdominal pain, or diarrhea. Hepatitis may be temporary (acute) or long term (chronic) depending on whether it lasts for less than or more than six months.

- Acute hepatitis B — After a person is first infected with hepatitis B, they are said to have acute hepatitis. Most people with acute hepatitis B recover uneventfully. However, in about 5 percent of adults (1 in 20) the virus makes itself at home in the liver, where it continues to make copies of itself for many years.his protein shows up in the blood 1 to 10 weeks after exposure to the hepatitis B virus and before a person starts to show symptoms of the infection. In people who recover, this protein usually disappears after 4 to 6 months. Its continued presence suggests that chronic infection has developed.

- approximately one week intervals will distinguish rapidly rising IgM anti-HAV levels associated with early acute hepatitis A infection from gradually decreasing or unchanging IgM anti-HAV levels often associated with late acute stage of HAV infection.

- Acute infection may cause nonspecific symptoms, such as fatigue, poor appetite, nausea, vomiting, abdominal pain, low-grade fever, jaundice, and dark urine; and clinical signs, such as hepatomeg-aly and splenomegaly. Fewer than 5 percent of adults acutely infected with hepatitis B virus progress to chronic infection. The diagnosis of hepatitis B virus infection requires the evaluation of the patient’s blood for hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B core antibody.

Viral Hepatitis 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 E Typical signs and symptoms of hepatitis include: an initial phase of mild fever, reduced appetite (anorexia), nausea and vomiting, lasting for a few days; some persons may also have abdominal pain, itching (without skin lesions), skin rash, or joint pain.

UNDERSTANDING HEPATITIS C Hep C can either be acute or chronic: Acute Hep C lasts a short time and occurs within the first 6 months of exposure to the Hep C virus. In some cases, the body can get rid of the virus on its own. If not, the infection will become chronic. Chronic Hep C is serious and long lasting. For 75%–85% of people with Hep C, an acute infection becomes chronic.

- An acute viral hepatitis panel may be ordered when a person has had blood tests done as part of a health checkup that show abnormal results on liver tests or when someone has acute symptoms associated with liver damage such as: 1  Fever, fatigue. 2  Loss of appetite.

Step 4: Conduct Descriptive Epidemiology The illustration above shows a point source epidemic of hepatitis A in which all of the cases occur within a one month period consistent with hepatitis A's average incubation period of about 30 days. The source is prolonged over an extended period of time and may occur over more than one incubation period.
