Abstract
We report emerging subtropical bimodal seasonality and alternating predominance of norovirus GII.4 and non-GII.4 genotypes in Hong Kong. GII.4 predominated in summer and autumn months and affected young children, whereas emergent non-GII.4 genotypes predominated in winter months and affected all age groups. This highly dynamic epidemiology should inform vaccination strategies.
摘要
我们报告了香港出现的亚热带双峰季节性以及诺如病毒GII.4和非GII.4基因型的交替主导情况。GII.4在夏季和秋季占主导地位，主要影响幼儿，而新出现的非GII.4基因型在冬季占主导地位，影响所有年龄组。这种高度动态的流行病学情况应为疫苗接种策略提供参考。
