US: 80,000 Flu Deaths Last Winter
United States health officials say an estimated 80,000 people died of influenza and problems resulting from the flu last winter.
The director for the U.S. Centers for Disease Control and Prevention (CDC) reported the number to The Associated Press. It represents the largest number of flu deaths nationwide in at least 40 years.
Health experts were expecting the winter of 2017-2018 to be a bad year for flu deaths, but not that bad.
Doctor William Schaffner is an expert on vaccines. He works at Vanderbilt University in Tennessee. Schaffner noted that 80,000 deaths is nearly two times as much as what health officials once considered a "bad year."
CDC officials say that between 12,000 and 56,000 Americans die every year from flu-related causes.
While 80,000 deaths seems high, the exact number could be even higher.
CDC officials do not have an exact count of how many people die from the flu each year. Influenza is a relatively common disease and not all flu cases are reported. Also, flu is not always listed on death records as the official cause of death. For that reason, the CDC must estimate the number of dead based on statistical models.
While last winter was a bad flu season in the U.S., it was not the worst.
The 1918 flu pandemic lasted nearly two years. Historians estimate that the disease was to blame for between 500,000 to 700,000 deaths during that period. The exact number is still not known.
One thing that made the 2017-2018 flu season so bad was that the strain of the flu virus was strong. Usually the disease kills the very young, the very old or those who are already sick. However, last winter, the flu killed many healthy Americans.
Another thing that made the flu season so deadly was that the flu vaccine was not as effective as experts had predicted.
In a 2017 statement to the press, the World Health Organization said that every year up to 650,000 deaths are connected with influenza or influenza-related illnesses. This is a new estimate by the U.S. CDC, the WHO and global health partners. This is more than the global estimate from ten years ago. At that time, experts estimated that between 250,000 to 500,000 people died from influenza or influenza-related illnesses.
Back in the U.S., health officials are predicting a weaker strain of flu virus this coming winter. Drug makers have made changes to the vaccine. Even though the vaccine did not work well last year, health experts still strongly suggest getting vaccinated.

威廉·沙夫纳（William Schaffner）博士是一名疫苗专家 。他在田纳西州的范德比尔特大学任职 。沙夫纳指出，8万人死亡的数据几乎是卫生官员预测的“糟糕的一年”的两倍 。
美国疾病控制和预防中心官员没有准确地统计出每年死于流感的人数 。流感是一种相对常见的疾病，并非所有流感病例都有报告 。另外，流感并不总能作为官方死亡原因列入死亡纪录 。因此，疾控中心必须根据统计模型估算死亡人数 。
1918年的流感大流行持续了近两年 。历史学家估计，那段时间，流感导致近50到70万人死亡，确切数字还不清楚 。
流感病毒的毒株很强也是导致2017到2018年流感季如此严重的原因之一 。通常这种疾病对老幼病弱是致命的 。然而，去年冬天的流感导致很多健康的美国人死亡 。
世界卫生组织在2017年向媒体发表的声明中称，每年多达65万人死于流感或流感相关疾病 。这是美国疾病控制和预防中心、世界卫生组织以及全球卫生合作伙伴的最新估计 。该数据比10年前的全球估计还要高 。当时，专家估计每年有25万到50万人死于流感或流感相关疾病 。
再回顾一下美国，卫生官员预测今年冬季将出现一次较弱的流感病毒 。制药商已经对疫苗进行了改良 。尽管去年流感疫苗效果不佳，但是卫生专家仍然强烈建议接种疫苗 。
