(1) It is estimated that about 0.2 to 26% of the general population in different countries are chronically infected by HCV. (2)(3) The hepatitis C virus is an enveloped RNA virus.

The only known reservoir for this virus is the human, although experiments have been conducted where it was transmitted to chimpanzees. The primary mode of transmission is parenterally, meaning that the virus is not taken into the body via the digestive tract, but via blood transfusions or uptake of blood products coming from unscreened donors.
