Chronic viral hepatitis is seen with all of the following viruses, except?

Chronic hepatitis is defined as symptomatic, biochemical, or serologic evidence of continuing or relapsing hepatic disease for more than 6 months. Etiology rather than the histologic pattern is the most impoant determinant of the probability of developing progressive chronic hepatitis. Chronic viral hepatitis is seen in HBV, HCV, HDV. Hepatitis A virus (HAV) infection is a self-limited disease and does not lead to chronic hepatitis or a carrier state. HAV and HEV (in immunocompetent hosts) do not cause chronic hepatitis.
