  Globally, Hepatitis E virus (HEV) is a major cause of acute viral hepatitis (AVH). HEV has been designated as a second class legal infectious disease since July 2020 in South Korea. To investigate the causative role of HEV and its clinico-epidemiological characteristics in AVH, a prospective, nationwide multicenter study including 12 institutions was performed from Feb to Nov 2020. As a result, among the 79 confirmed AVH patients, the most common cause was HAV (n=60, 76%) followed by HEV (n=7, 9%), HCV (n=3, 4%), HBV (n=2, 3%) and others (n=7, 9%) including Epstein-Barr virus and cytomegalovirus. HEV patients showed an average 10 year-older age, higher male proportion, and higher rate of intake history of animal blood or bile and raw meat or fish than HAV patients. For the diagnosis of HEV infection, 2 anti-HEV IgM tests were simultaneously performed for each sample, which showed a low concordance rate (60%) of positive result. The HEV RNA PCR test in serum was positive in only 1 of the 6 available HEV samples. Therefore, this study concluded that standardization of diagnostic tests is urgently needed.

  Acute gastroenteritis is a global public health concern. This study aimed to analyze the trend and characteristics of acute viral gastroenteritis through a national surveillance network. Enteric viruses were detected in 9,510 of 31,750 (30.1%) cases assessed in 2013-2019 by EnterNet. The most prevalent pathogens were norovirus (15.2%) and group A rotavirus (9.7%); most infections were reported in 2017 (34.0%). Norovirus and rotavirus co-infections were the most common. Norovirus infections were prevalent among 1-year-old children (1,835 out of 9,510 cases) and most prevalent during winter; group A rotavirus were common during spring. Seasonality was not observed among enteric adenovirus, astrovirus, and sapovirus. The prevalent viral genotypes detected included-norovirus GII.4, enteric adenovirus F41, astrovirus genotype 1 and sapovirus GI.1. However, changes in enteric virus trends were noted during the study period. Norovirus prevalence extended into spring and new genotypes of enteric adenovirus, astrovirus, and sapovirus were identified. These surveillance data elucidate enteric virus epidemiological characteristics.
