Acute diarrheal disease is an important cause of morbidity and mortality in children under five years of age and is associated with about half a million deaths annually worldwide. The Korea Centers for Disease Control and Prevention, together with the Korean Institute of Health and Environmental Research, and more than 70 cooperative hospitals, examined the prevalence of the virus that causes acute diarrhea diseases in Korea. A total of 9,948 patient fecal samples were collected for one year from January to December 2018, and analyzed according to the guidelines for the management of waterborne and foodborne diseases. A total of 1,469 cases (detection rate; 14.8%) of acute diarrheal diseases were detected. Among them, 750 (7.5%) norovirus and 406 (4.1%) group A rotavirus cases were detected; accounting for 51% of the total detection rate. By age, it was detected at the age of 5 years or younger, and the highest was 37.6%. Norovirus, a pathogen that is generally understood to exhibit wintertime seasonality, measured high detection rates in January (14.7%), February (14.5%) and December (13.4%), 2018. The most prevalent genotypes of viral pathogens detected were GII.4 for norovirus and F41 for enteric adenovirus and astrovirus, and sapovirus were the most prevalent in type 1 and GI groups, respectively. According to this study’s findings, in order to prevent the spread of pathogens and reduce the number of mass outbreaks, continuous and systematic monitoring, early diagnosis and in-depth analysis are necessary.
