SEN virus (SENV) was discovered in 1999 as a DNA virus with hepatotropic properties. Nine genotypes (A-I) have been identified with genotypes D and H being more prevalent in cases of chronic hepatitis. Attempts to determine whether SENV causes liver disease have been hampered by limited diagnostic testing.
