Hepatitis caused by hepatitis B virus; one method of transmission is by transfusion of contaminated blood or blood products.

INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.

Hepatitis is inflammation of the liver. Inflammation is swelling that happens when tissues of the body are injured or infected. It can damage your liver. This swelling and damage can affect how well your liver functions. Hepatitis B is a type of viral hepatitis. It can cause an acute (short-term) or chronic (long-term) infection. People with an acute infection usually get better on their own without treatment. Some people with chronic hepatitis B will need treatment. Thanks to a vaccine, hepatitis B is not very common in the United States. It is more common in certain parts of the world, such as sub-Saharan Africa and parts of Asia. Hepatitis B is caused by the hepatitis B virus. The virus spreads through contact with blood, semen, or other body fluids from a person who has the virus. Anyone can get hepatitis B, but the risk is higher in: Infants born to mothers who have hepatitis B; People who inject drugs or share needles, syringes, and other types of drug equipment; Sex partners of people with hepatitis B, especially if they are not using latex or polyurethane condoms during sex; Men who have sex with men; People who live with someone who has hepatitis B, especially if they use the same razor, toothbrush, or nail clippers; Health care and public-safety workers who are exposed to blood on the job; Hemodialysis patients; People who have lived in or traveled often to parts of the world where hepatitis B is common; Have diabetes, hepatitis C, or HIV. Often, people with hepatitis B don't have symptoms. Adults and children over 5 are more likely to have symptoms than younger children. Some people with acute hepatitis B have symptoms 2 to 5 months after infection. These symptoms can include: Dark yellow urine; Diarrhea; Fatigue; Fever; Gray- or clay-colored stools; Joint pain; Loss of appetite; Nausea and/or vomiting; Abdominal pain; Yellowish eyes and skin, called jaundice. If you have chronic hepatitis B, you may not have symptoms until complications develop. This could be decades after you were infected. For this reason, hepatitis B screening is important, even if you have no symptoms. Screening means that you are tested for a disease even though you don't have symptoms. If you are at high risk, your health care provider may suggest screening. In rare cases, acute hepatitis B can cause liver failure. Chronic hepatitis B can develop into a serious disease that causes long-term health problems such as cirrhosis (scarring of the liver), liver cancer, and liver failure. If you have ever had hepatitis B, the virus may become active again, or reactivated, later in life. This could start to damage the liver and cause symptoms. To diagnose hepatitis B, your health care provider may use many tools to make a diagnosis: A medical history, which includes asking about your symptoms; A physical exam; Blood tests, including tests for viral hepatitis. If you have acute hepatitis B, you probably don't need treatment. Some people with chronic hepatitis B don't need treatment. But if you have a chronic infection and blood tests show that hepatitis B could be damaging your liver, you may need to take antiviral medicines. The best way to prevent hepatitis B is to get the hepatitis B vaccine. You can also reduce your chance of hepatitis B infection by: Not sharing drug needles or other drug materials; Wearing gloves if you have to touch another person's blood or open sores; Making sure your tattoo artist or body piercer uses sterile tools; Not sharing personal items, such as...

(hepatitis b infection) A viral infection caused by the hepatitis B virus.

Hepatitis B is a worldwide healthcare problem, especially in developing areas. An estimated one third of the global population has been infected with the hepatitis B virus (HBV).

Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months. Having chronic hepatitis B increases your risk of developing liver failure, liver cancer or cirrhosis - a condition that permanently scars of the liver.

Hepatitis B virus (HBV) is a DNA virus transmitted by percutaneous and permucosal routes. HBV infection is also a sexually transmitted disease. Infection may result in a self-limited disease requiring no treatment, particularly in adult-acquired infection, but it may also result in a chronically infected state, particularly if it is...

Hepatitis B, infectious disease of the liver, the causative agent of which is known as hepatitis B virus (HBV). The course and severity of illness associated with HBV infection varies widely. Some persons are asymptomatic, for example, whereas others experience acute illness and eliminate the virus...
