BACKGROUND AND PURPOSE: Rotavirus was the most common virus in benign @entity410 with mild @entity1902 (CwG), with an incidence of 40-50%. As @entity1902 has decreased since introduction of rotavirus vaccine, we investigated the incidence of CwG and rotavirus positivity after introduction of the vaccine. METHODS: We retrospectively reviewed the medical records of 987 @entity1 aged between 3months and 3years who were admitted to the Chonnam National University Hospital between March 2005 and February 2014 due to their first @entity410 and enrolled 102 @entity1 with CwG. The incidences of CwG among @entity410 @entity1 and stool rotavirus positivity in CwG @entity1 were compared between two periods: period I (March 2005-February 2010) and period II (March 2010-February 2014). Other viruses in stools were also reviewed. RESULTS: The incidence of CwG were 8.47% (45 among 531 @entity1 ) in period I and 12.50% (57 among 456 @entity1 ) in period II (P=0.018). Stool rotavirus was checked in 85.29% (87 @entity1 ): 82.22% (37 @entity1 ) in period I and 87.72% (50 @entity1 ) in period II (P=0.166). The positivity of rotavirus was 40.54% (15 @entity1 ) in period I and 16.00% (8 @entity1 ) in period II (P=0.01). In the @entity1 without @entity1902 , 30 @entity1 were test for other viruses. Norovirus was the most common (56.67%, 17 @entity1 ) and was more frequent in period II than I (71.43% versus 22.22%, P=0.018). CONCLUSION: After introduction of rotavirus vaccine, rotavirus-associated CwG has decreased but the incidence of CwG has increased due to an increase of norovirus.
