Several diseases of the liver, collectively known as hepatitis, are caused by viruses. The viruses involved, five of which have been reasonably well characterized, come from a wide range of virus families. Hepatitis A virus is a picornavirus, a small single strand RNA virus; hepatitis B virus belongs to the hepadnavirus family of double stranded DNA viruses; hepatitis C virus is a flavivirus, a single stand RNA virus; hepatitis E, also an RNA virus, is similar to a calicivirus. Hepatitis D which is also known as Delta agent is a circular RNA that is more similar to a plant a viroid than a complete virus.
Hepatitis D requires co-infection with the B type.
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).
Hepatitis A is a type of RNA virus belonging to the Picornaviridae family. It primarily infects the liver and is transmitted through oral-fecal route, contaminated food or water, or close personal contact with an infected person.
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 C and hepatitis E have no vaccine to prevent the disease. Although there is no vaccine to prevent hepatitis D, you can only get this type if you're also infected with type B. Therefore, hepatitis B vaccine indirectly prevents hepatitis D.

The hepatitis B illness is caused by the hepatitis B virus, a species of the genus Orthohepadnavirus.
Hepatitis can be detected in the blood typically within 1 to 10 weeks after exposure, depending on the type of hepatitis virus. For example, hepatitis A antibodies usually appear within 2 to 6 weeks, while hepatitis B can be detected in as little as 4 weeks. Hepatitis C antibodies may take 4 to 10 weeks to become detectable. Testing methods vary, so the exact timing can differ based on the specific virus and the type of test used.
Hepatitis D, also known as delta hepatitis, can only exist as a co-infection with hepatitis B. It requires the presence of the hepatitis B virus to replicate and cause infection. Individuals can become infected with hepatitis D simultaneously with hepatitis B or can acquire it later, but it is dependent on hepatitis B for its existence.
I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the liver already present. I started on antiviral medications which reduced the viral load initially. After a couple of years the virus became resistant. I started on HEPATITIS B Herbal treatment from ULTIMATE LIFE CLINIC (ww w.ultimatelifeclinic .com) in March, 2020. Their treatment totally reversed the virus. I did another blood test after the 6 months long treatment and tested negative to the virus. Amazing treatment! This treatment is a breakthrough for all HBV carriers.
Hepatitis C is caused by the hepatitis C virus (HCV), which is an RNA virus belonging to the Flaviviridae family. It primarily infects the liver and can lead to chronic liver disease, including cirrhosis and liver cancer. HCV is transmitted through blood-to-blood contact, often via shared needles or inadequate medical practices.
It is called infective hepatitis or hepatitis A
