What is hepatitis A?
Hepatitis A is a potentially serious disease caused by a virus which attacks the liver. Anyone can get it. The virus is transmitted through contaminated food, such as raw or insufficiently cooked seafood and shellfish, and contaminated water. It can be passed by someone infected with the virus who doesn't wash his/her hands properly after a bowel movement and
then touches something you eat.
Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). Hepatitis A is primarily spread by fecal-oral transmission. Consumption of food and drink that have been contaminated with hepA virus should be avoided. People should be especially careful with shellfish, fruits, vegetables, water, and ice that have not been properly cleaned or handled. Although not usually as serious as other types of viral hepatitis, hepatitis A causes inflammation that affects your liver's ability to function. This is significant because the liver performs hundreds of tasks that are essential for health and life.
The virus that causes hepatitis A (hepA) is 27 nanometers in diameter. It contains a single strand of positive sense RNA, surrounded by an icosahedral protein coat. The hepA virus is a member of the picornaviridae family and has recently been reassigned to the genus Hepatovirus. The virus multiples inside the intestinal epithelium. On rare occasions, the hepA virus enters the bloodstream, and replicates in the liver where it is spread to the small intestines through bile secretions.
More information on hepatitis
What is hepatitis? - Hepatitis is inflammation of the liver. Hepatitis is characterized by jaundice, enlarged liver, fever, fatigue and abnormal liver function tests.

What's the treatment for autoimmune hepatitis? - Not all patients with autoimmune hepatitis require treatment. Patients are treated with Prednisone including 6 mercaptopurine with or without steroids.
What is alcoholic hepatitis? - Alcoholic hepatitis is a precursor to chronic liver disease and cirrhosis. Alcoholic hepatitis is distinct from cirrhosis caused by long term alcohol consumption.
What causes alcoholic hepatitis? - Alcoholic hepatitis usually occurs after years of excessive drinking. Malnutrition contributes to liver disease.
What are the symptoms of alcoholic hepatitis? - Symptoms of alcoholic hepatitis include abdominal tenderness, spider-like blood vessels in the skin, ascites, poor appetite.
How is alcoholic hepatitis diagnosed? - Diagnostic procedures for alcoholic hepatitis may include specific laboratory blood tests, ultrasound (sonography), and liver biopsy.
What is the treatment for alcoholic hepatitis? - Cessation or marked reduction in alcohol intake is critical in the treatment for alcoholic hepatitis. A multidisciplinary therapy is adopted.
What're complications of alcoholic hepatitis? - Complications of alcoholic hepatitis include variceal bleeding, hepatic encephalopathy, coagulopathy and thrombocytopenia, ascites.
What is hepatitis A? - Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus (HAV). Hepatitis A is primarily spread by fecal-oral transmission.
What causes hepatitis A? - The hepatitis A virus is found in the stools (feces) of people with hepatitis A. Hepatitis A is primarily spread by fecal-oral transmission.
Who is at risk of hepatitis A? - The highest rates of hepatitis A are among children and young adults. Infected people can transmit it to others if they do not take strict sanitary precautions.
What are the symptoms of hepatitis A? - Symptoms of hepatitis A may include fever, nausea, vomiting, jaundice, diarrhea, fatigue, abdominal pain, dark urine and appetite loss.
How is type A hepatitis diagnosed? - The patient will have to have blood tests to confirm the diagnosis of hepatitis A and to see whether your liver has been damaged.
What's the treatment for hepatitis A? - No specific treatment exists for hepatitis A. Initial therapy often consists of bed rest. Gammaglobulin may reduce the severity of the disease.
How to prevent hepatitis A? - Hepatitis A can be prevented by good hygiene and sanitation. Good hygiene in handling food and avoiding contamination of water supplies is important.
Who needs to be vaccinated against hepatitis A? - A vaccine to protect against hepatitis A is available for people who are at high risk of being infected, and for those with existing liver disease.
What is hepatitis B? - Hepatitis B is an inflammation of the liver caused by the hepatitis B virus. The virus that causes hepatitis B is a member of the Hepadnavirus family.
What causes hepatitis B? - Hepatitis B virus is easily spread by direct contact with the blood or body fluids of an infected person. Hepatitis can interfere with normal liver functions.
Who is at the risk of hepatitis B? - Anyone of any age, race, nationality, sex or sexual orientation can be infected with HBV. Sexual activity is an important route for viral transmission of hepatitis B.
What're the symptoms of hepatitis B infection? - Symptoms of hepatitis B infection include nausea (upset stomach), loss of appetite, vomiting, fatigue, and abdominal cramps.
How is hepatitis B diagnosed? - Hepatitis B is diagnosed from the results of specific HBV blood tests (serologies) that reflect the various components of the HBV.
What's the treatment for hepatitis B? - There is no treatment for acute hepatitis B. Treatment of chronic hepatitis B may involve the use of medications such as the antiviral medication.
What's the treatment for chronic hepatitis B? - Treatment of chronic hepatitis B may involve the use of medications such as the antiviral medication alpha interferon.
How to prevent hepatitis B? - Hepatitis B is a preventable disease. Protective practices should be promoted to avoid the risk of transmitting the virus sexually or by contaminated blood.
What about the vaccinations for hepatitis B? - Vaccination against hepatitis B stimulates the body's immune defenses and protects most people. Vaccination reduces the risk for liver cancer.
What is Hepatitis B immune globulin (HBIG)? - Hepatitis B immune globulin (HBIG) is a blood plasma product that can prevent hepatitis B if given within 14 days of an exposure to an infected individual.
What is hepatitis C? - Hepatitis C is a form of hepatitis (liver inflammation). Hepatitis C virus infects the liver and can cause hepatitis.
What causes hepatitis C? - Hepatitis C virus (HCV) is one of the viruses, which together account for the vast majority of cases of viral hepatitis.
