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).
Hepatitis is inflammation in the liver caused by the virus hepatitis B.
Hepatitis A or B or C involves an infection of the liver caused by a virus.
The causative agent for Hepatitis B is Hepatitis B virus.
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.)
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.
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.
The scientific name of hepatitis B is Hepatitis B virus (HBV).
Usually caused by hepatitis B virus.
The hepatitis B illness is caused by the hepatitis B virus, a species of the genus Orthohepadnavirus.
Chronic hepatitis B is a liver disease caused by a virus. Being a carrier of hepatitis B means that you are infected with the virus and can transmit it to others, but you may not have the disease
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.
No it is not. It is a virus.
