Viral infections are the cause of most acute Hepatitis. Hepatitis comes in 7 not so delicious flavours: Hepatitis A, B, C, D - Agent (which requires the presence of the hepatitis B virus to form), Hepatitis E, F, and G. None of these are very yummy, and should be avoided at all costs.
The most common of the 7 is Hepatitis A. It is transmitted through the orofecal route, or in other words, contaminated food. This one is the easiest to contract, but it does not reach a chronic stage, so the body is able to build up an immunity against it by creating antibodies. An excellent preventative measure is to get a Hepatitis A vaccination. This will prevent infection of the virus.
Hepatitis has a close brother - Hepatitis B. This evil twin is also very easy to contract. you can get it through blood, tattoos, sexually, and you can even inherit it from your mother when you are born. Hep. B can be acute, however, some peoples' bodies are unable to produce antibodies against it, thus turning an acute virus into a chronic one.
The easiest way to avoid contracting Hepatitis is simple cleanliness and vaccinations. click the link to my website at the bottom for more information on all forms of Hepatitis.
