Background: As discussed previously, influenza (flu) is a common respiratory disease that causes significant morbidity and mortality worldwide (see pearl from October 1. 2014). We are now in the midst of the current flu season.
背景：正如之前所讨论的，流感作为一个呼吸系统常见病在世界范围内有着很高的发病率和死亡率（参考2014年10月的文章），我们现在正处在流感流行季节。

Current Update: This year’s vaccine was only a partial match (<50%) for the current influenza A (H3N2) circulating virus, so there is a significant potential for a “bad” flu season with widespread disease and severe illness. Currently, influenza is now widespread throughout the US, with some states reporting more activity than others. The CDC has a weekly surveillance map that highlights current disease spread.
目前更新：今年的疫苗仅部分匹配（小于50%）当前的A型流感病毒，所以很可能形成传播广泛和病情严重的恶性流感季节。目前，流感在美国广泛传播，在某些州更加严重，疾控中心每周发布调查报告强调目前的疾病传播情况。

Bottom Line 要点:
• Remember that influenza annually causes between 250,000 and 500,000 deaths worldwide.
• Your emergency department will likely see many individuals with influenza this year, even if the patient received the vaccination.
• Know your emergency department protocols and policies for cohorting influenza patients and addressing droplet isolation precautions.
流感每年导致世界范围内250,000 到 500,000人的死亡。
今年急诊可能看到更多的流感患者，即使患者接收了疫苗接种。
熟悉应对群发流感人群的急诊流程和政策，加强隔离切断飞沫传播。
