摘要:
The present invention provides a method of predicting potential severity of hepatitis, includes determining that hepatitis in a subject is potentially severe when it is detected that any amino acid is mutated to an amino acid of genotype-4, the any amino acid being amino acid of an amino acid sequence in a region encoded by ORF1 of an HEV genome RNA of genotype 3, and the HEV genome RNA being contained in a specimen nucleic acid taken from the subject infected with genotype-3 HEV.
