Abstract
Through July 2009, a total of 43,677 laboratory-confirmed cases of influenza A pandemic (H1N1) 2009 were reported in the United States, which is likely a substantial underestimate of the true number. Correcting for under-ascertainment using a multiplier model, we estimate that 1.8 million-5.7 million cases occurred, including 9,000-21,000 hospitalizations.
摘要
截至 2009 年 7 月，美国共报告了 43677 例经实验室确诊的甲型 H1N1 流感大流行病例，这很可能大大低估了实际病例数。我们使用倍增模型校正漏报情况后估计，有 180 万至 570 万例病例发生，包括 9000 至 21000 例住院病例。
