Hepatitis B is what we used to originally known as just simply serum hepatitis. Hep B has been recognized as this new name since World War II. The virus is responsible for current epidemics in parts of Asia and Africa. Recognized as endemic in China and various other parts of Asia, the Hepatitis B virus has infected over one third of the world's current population.
Hepatitis B is in the Hepadnavirus family. Meaning that it consists of a proteinaceous core particle that has the viral genome inside of it in the form of double stranded DNA. It also has an outside lipid-based envelope that contains embedded proteins. These envelope proteins on the outside are involved in viral binding and release into susceptible cells. Where as the inner capsid refinds the DNA genome to a cell's nucleus where it transcribes viral mRNAs. Although HIV, the virus that causes AIDS, and Hepatitus are not related they are both viruses that use reverse transcription process. This also include HTLV. Hepatitis B's genome is DNA, and reverse transcription is one of the latter steps of the entire process which results in making new viral particles. HIV on the other hand has an RNA genome and reverse transcription is one of the first steps in replication of the virus.
Hepatitis B is most commonly transmitted through direct exposure to bodily fluids that contain the virus. This is a wide category but in most cases includes: - Re-using contaminated needles and syringes - Uncleanly Blood transfusions - Unprotected sexual contact - Direct transmission from mother to child during childbirth
The dominant mode of transmission depends largely on the prevalence of the disease in a given area. For example if areas such as North America drug abuse and unprotected sex are the primary mode of infection. Where as in areas such as such as China where Hepatitis B is very prevalent, the vertical transmission(mother to child) is the most common. A mother who is positive for the Hepatitis B surface virus has a 20% risk of passing the infection to her offspring during birth. That percentage can rise to as high as 90% if the mother is also infected with the hepatitis B e antigen.
The older a person is at the time of infection, the greater the risk that their body will not clear the infection. Hepatitis B infection can lead to a permanent inflammation of the liver, the result of this inflammation leads cirrhosis. These affects largely increase the likelyhood of developing liver cancer.

A Quick Note From The Publisher... If you like the article above, you may be interested in the following article which is also related to Hepatitis... Hepatitis C Are you experiencing jaundice, fatigue, dark urine, abdominal pain, loss of appetite, and nausea? If you experience all these, you can be suffering from hepatitis C, a disease of the liver, which is caused by the hepatitis C virus or HCV. This disease is transmitted when the blood from an infected person enters the body of an uninfected person. It can be spread through sharing needles. It can also be transmitted from an infected mother to her baby during birth. The long-term effects of this disease include chronic infection, chronic liver disease, and death. Unlike other diseases, hepatitis C has no vaccine, but there are blood tests that are available to check for this disease, especially if you were notified that you received blood from an infected donor or if you have ever injected illegal drugs. You should also contact your medical provider for a blood test if you have ever been on long-term kidney dialysis or if you have evidence of liver disease. The blood tests that will be conducted are anti-HCV, qualitative tests to detect presence or absence of virus, and quantitative tests to detect amount of virus. These tests can determine if you have been infected with HCV. Your doctor can recommend you to undergo one or a combination of these tests. Since there is no vaccine to hepatitis C, prevention is one of the best things that a person can do to avoid the risk factors. You should never shoot drugs, or if you can’t stop, at least never share needles. Also do not share personal care items that might have blood on them, like razors. If you are thinking about getting a tattoo or ear piercing, you might as well think twice because there is risk of getting infected if the tools have someone else’s blood on them. Keep all these preventive measures in mind because...
