Hepatitis C has no alternative.
 Hepatitis C is also associated with autoimmune disorders such as Sjgren's syndrome, lichen planus, a low platelet count, porphyria cutanea tarda, necrolytic acral erythema, insulin resistance, diabetes mellitus, diabetic nephropathy, autoimmune thyroiditis, and B-cell lymphoproliferative disorders
Hepatitis C infection rates increased substantially in the 20th century due to a combination of intravenous drug abuse and the reuse of poorly sterilized medical equipment
