Hepatitis is an inflammation of the liver that is most often caused by a virus, though infections, diseases, and toxins may also contribute.[i] The five predominant viruses are Hepatitis A, B, C, D, and E, with B and C leading to chronic disease for hundreds of millions of people. Hepatitis A and E are generally caused by consuming infected food or beverages, whereas B, C, and D involve contact with infected bodily fluids. Hepatitis D only affects people with Hepatitis B.[ii] Vaccines exist for every one of these viruses except for Hepatitis C,[iii] and as such it constitutes a greater risk for many people.
