BACKGROUND
Influenza B is often regarded as the milder form of the disease. The early 2012-2013 season in Wales saw the highest rate of influenza B-associated primary care consultations since 1994-1995 and considerable hospitalisations.
OBJECTIVES
This report summarises features of the first 100 confirmed cases during 2012-2013 in Wales.
METHODS
Case information was sourced from routine laboratory testing and virological surveillance.
RESULTS AND CONCLUSIONS
Influenza B (Yamagata lineage) viruses dominated, mainly affecting younger adults, admission to critical care was unexpectedly common. Low vaccine uptake amongst at-risk patients may have contributed to the burden of influenza in secondary care in Wales.
背景
乙型流感通常被认为是一种较轻的疾病。在威尔士，2012-2013 年早期的流感 B 型相关初级保健咨询量达到了自 1994-1995 年以来的最高水平，并且有相当数量的住院治疗。
目的
本报告总结了 2012-2013 年威尔士前 100 例确诊病例的特征。
方法
病例信息来自常规实验室检测和病毒学监测。
结果和结论
乙型流感（山形系）病毒占主导地位，主要影响年轻成年人，进入重症监护病房的情况出人意料地常见。高危患者的疫苗接种率低可能导致威尔士二级保健机构流感负担加重。
