Hepatitis

Hepatitis is an inflammation of the liver, which causes liver damage. Hapatitis can be caused by alcoholism, INH, but many kinds are caused by viruses.
== Common Symptoms ==
Fever, Jaundice, Brown urine
== Hepatitis A - RNA virus ==
Infectious Hepatitis (Fecal/oral route), often found in uncooked or undercooked food. It is acute, 2-3 weeks, so no significant liver damage is done.
== Hepatitis B - DNA virus ==
Serum Hepatitis, blood associated
Transmission: through blood: blood transfusion, needles, dry blood or through placenta.
Chronic – in 6% of cases. Causes more significant liver damage. It has a 2% mortality rate, and causes a type of cancer called Hepatoma. 
Vaccine is main method of prevention, and treatment is done with Alpha Interferon with Tenofovir. 
In at least 1/3 of individuals were "cured", in that virus replication has been suppressed below detection levels.
== Hepatitis C- RNA virus ==
Classic Non-A Non-B Hepatitis transmitted through blood transfusions. It is the main cause of post-transfusion hepatitis, and occurs in 1/100k transfusions because it is hard to detect. Remains in you for 10-30 years and causes a chronic infection in up to 80% of all individuals 
There is no vaccine, but the treatment with Peg Interferon, Ribavirin, and Telaprevir can cure 80% of the individuals. 
== Hepatitis D - RNA virus ==
Called Delta Agent, and it’s not a complete virus. Not infectious alone but when transmitted with Hepatitis B; Hepatitis B gains an envelope and increases damage to the liver.
Prevention: Vaccine for Hepatitis B protects you from damages of Hepatitis D as well.
== Hepatitis E - RNA virus ==
Infectious Non-A Non-B Hepatitis 
Symptoms: Similar to Hepatitis A but higher mortality rate in pregnant women. 
== Hepatitis F ==
is really just Hepatitis C. So it's not really a thing.
== Hepatitis G – RNA virus ==
Transmission: Blood borne. Symptoms vary from flu-like syndrome to death.
Co-infection with Hepatitis G slows down progression of Hepatitis C and HIV.
