Liver Diseases
Viral Hepatitis occurs in five types A, B, C, D, E
Hepatitis A: benign; spread by oral-fecal contact
Hepatitis B: formerly called “serum hepatitis” spread by blood, urine, feces, saliva, and semen

Liver Diseases
Hepatitis C: spread by blood or sex Hepatitis D: “delta virus” requires
presence of hepatitis B to replicate Hepatitis E: spread through fecal-oral
contact, commonly due to water contamination
