Hepatitis A or B or C involves an infection of the liver caused by a virus.
Hepatitis B is an infectious disease caused by the Hepatitis B virus (HBV) of the Hepadnavirus family. It only has tropism for humans (only infects humans).
Perhaps. But usually hepatitis is caused by a virus or a bacteria.
Hepatitis B is a viral infection. It is a virus. Only one virus causes Hepatitis B. It infects the liver. A vaccine exists to prevent it. It is blood borne. If you are in the same room with someone who has it, you will not catch it. Do not share needles, razors, or anything that could move their body fluids to you. Hepatitis B can be treated. Other liver infections exist. Hepatitis A generally results when an infected person prepares your food. Hepatitis C is blood borne. Anything one person does that gets body fluids from one person into another spreads the virus. Hepatitis D, E, F, G, H, I, J, K, L, and M also exist. Those liver infections are caused by different pathogens. (I do not have the first idea about any of those diseases. Someone came back from Atlanta and passed on that information.)
Hepatitis is actually quite a general term which means inflammation of the liver and so has many causes for example drug-induced, alcoholic, autoimmune or infectious. On the whole when most people refer to hepatitis they refer to infectious hepatitis often caused by the hepatitis viruses types B & C which have the potential to cause long term (chronic) hepatitis. There are other forms of the hepatitis virus family including types A, D & E and there are other forms of virus which can cause hepatitis. There are non-viral infectious causes of hepatitis including toxoplasma and Q fever (which is a bacteria) but these are rare.
The hepatitis virus is actually named that particular virus for which it refers to. For example, the virus for hepatitis B is called the hepatitis B virus (HBV), and the virus for hepatitis C is called hepatitis C virus (HCV), and so on.
The causative agent for Hepatitis B is Hepatitis B virus.
Hepatitis B is caused by the Hepatitis B virus (HBV). Hepatitis C is caused by the Hepatitis C virus (HCV). Hepatitis B virus belongs to the family Hepadnaviridae, and the genus Orthohepadnavirus. Hepatitis C virus belongs to the family Flaviviridae, and the genus Hepacivirus.
Hepatitis D requires co-infection with the B type.
Hepatitis A.
Hepatitis is caused by blood borne pathogens. The pathogens themselves conveniently share similar names to the type of hepatitis they cause: The pathogen that causes Hepatitus A is known as the Hepatitis A Virus (HAV), the pathogen that causes Hepatitus B is known as the Hepatitis B Virus (HBV) and the pathogen that causes Hepatitus C is known as the Hepatitis C Virus (HCV).
