During 2009, a total of 10,844 laboratory-confirmed cases of pandemic (H1N1) 2009 were reported in Beijing, People's Republic of China. However, because most cases were not confirmed through laboratory testing, the true number is unknown. Using a multiplier model, we estimated that ≈1.46-2.30 million pandemic (H1N1) 2009 infections occurred.
2009 年期间,中华人民共和国北京市共报告实验室确诊的甲型 H1N1 流感病例 10844 例。然而,由于大多数病例未经实验室确诊,因此实际病例数尚不清楚。使用倍增模型估计,北京市发生的甲型 H1N1 流感 2009 感染人数约为 146 万至 230 万例。
