摘要: In 2012, a new norovirus GII.4 variant (GII.4 Sydney) emerged and caused the majority of acute gastroenteritis outbreaks in Australia, Asia, Europe, North America. We examined epidemiologic molecular virologic characteristics reported determined to be by Taiwan from January 2012 December 2013. A total 253 (45.7%) 552 tested positive for norovirus, which 165 (65.5%) were typed as Sydney. Sydney all geographic areas occurred most frequently schools (35.8%) long-term care facilities (24.2%). Person-to-person transmission was identified 116 (70.3%) outbreaks. Phylogenetic analyses full-length ORF2 eight specimens indicated that strains detected closely related globally. Continued outbreak surveillance strain typing are needed provide information on trends novel strains. J. Med. Virol. 87:1462–1470, 2015. © 2015 Wiley Periodicals, Inc.
