Hepatitis B News, Articles and Research.

Hepatitis B. Hepatitis B is caused by the hepatitis B virus, which is spread in the blood of an infected person. It's a common infection worldwide and is usually spread from infected pregnant women to their babies, or from child-to-child contact. In rare cases, it can be spread through unprotected sex and injecting drugs. Hepatitis B is.

Acute hepatitis B is the period of illness that occurs during the first one to four months after acquiring the virus.Most healthy adults do not develop significant symptoms during acute infection. Early symptoms may be non-specific, including fever, a flu-like illness, and joint pains. Symptoms of acute hepatitis may include: loss of appetite.

Nucleic acid polymers: Broad spectrum antiviral activity, antiviral mechanisms and optimization for the treatment of hepatitis B and hepatitis D infection (open access) Antiviral Research, Available online 9 July 2016 Andrew Vaillant. A historical perspective on the discovery and elucidation of the hepatitis B virus.

Hepatitis C is a blood-borne virus (BBV); it lives mainly in the liver and moves around the body in the blood. It is spread by blood to blood contact. The hepatitis C virus is highly infectious; this means you can get the virus even if you have only been in contact with a very small amount of it. It can be passed on through open cuts, wounds or.

Hepatitis B virus is a human hepatotropic DNA virus that can cause a lifelong chronic infection and progressive liver disease. This Primer discusses the epidemiology, mechanisms, diagnosis.

Hepatitis D, which is transmitted through contact with infectious blood, occurs only among people with hepatitis B infection. Why Is the Study of Hepatitis a Priority for NIAID? Hepatitis B, C, and D afflict more than half a billion people worldwide and are responsible for more than a million deaths a year. Chronic infection with these viruses.

Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer.

People with hepatitis C often worry about giving it to others that they live with. However, it would be very hard to transmit HCV unless there is direct blood to blood contact. Things like razors, toothbrushes, nail clippers and other personal hygiene items can spread hepatitis C, but it is difficult to do so.

Hepatitis C was first discovered in the 1980s when it became apparent that there was a new virus (not hepatitis A or B) causing liver damage. Before being properly identified in 1989 it was originally known as non-A non-B hepatitis. In 1991 a screening process was developed making it possible to detect HCV in blood samples. As a relatively new.

Hepatitis B (HBV) is 50 to 100 times easier to transmit sexually than HIV ( the virus that causes AIDS). HBV has been found in vaginal secretions, saliva, and semen. Oral sex and especially anal.

Hepatitis B Although a vaccine to prevent hepatitis B infection is available, hepatitis B-induced liver cirrhosis and liver cancer kill about 3,000 people in the United States and roughly 620,000 people worldwide each year. The virus can be spread. From mother to child during childbirth; Through sex with an infected partner.

Chronic hepatitis B virus infection is a global public health threat that causes considerable liver-related morbidity and mortality. It is acquired at birth or later via person-to-person transmission. Vaccination effectively prevents infection and chronic hepatitis B virus carriage. In chronically infected patients, an elevated serum hepatitis B virus DNA concentration is the main risk factor.
