The recent increase in the number of cases of indigenous hepatitis E virus (HEV) infection highlights the importance of identifying the transmission routes for the prevention of such infections. Presented herein is the first case of acute HEV infection after ingesting wild roe deer meat in South Korea. A 43-year-old male presented with abdominal discomfort and jaundice. He had not recently traveled abroad, but had eaten raw roe-deer meat 6-8 weeks before the presentation. On the 7th day of hospitalization the patient was diagnosed with acute viral hepatitis E. Phylogenetic analysis of his serum revealed genotype-4 HEV. This case supports the possibility of zoonotic transmission of HEV because the patient appears to have been infected with genotype-4 HEV after ingesting raw deer meat.

BACKGROUND/AIMS: The distribution of hepatitis C virus (HCV) genotypes varies geographically. In Korea, genotypes 1 and 2 comprise more than 90% of HCV infections, while genotype 6 is very rare. This study compared the clinical and epidemiological characteristics of patients with genotype 6 HCV infection with those infected with HCV genotypes 1 and 2. METHODS: This was a prospective, multicenter HCV cohort study that enrolled 1,173 adult patients, of which 930 underwent HCV genotype analysis, and only 9 (1.0%) were found to be infected with genotype 6 HCV. The clinical and epidemiological parameters of the genotypes were compared. RESULTS: The patients with genotype 6 HCV had a mean age of 41.5 years, 77.8% were male, and they had no distinct laboratory features. A sustained virologic response (SVR) was observed in four (67%) of six patients who received antiviral therapy. Risk factors such as the presence of a tattoo (n=6, 66.7%), more than three sexual partners (n=3, 33.3%), and injection drug use (n=3, 33.3%) were more common among genotype 6 patients than among genotypes 1 or 2. CONCLUSIONS: The epidemiology and treatment response of patients infected with genotype 6 HCV differed significantly from those with genotypes 1 or 2, warranting continuous monitoring.
