The first laboratory-confirmed cases of infection with pandemic influenza A(H1N1) 2009 in the Western Pacific Region were reported on 28 April 2009. By 11 June 2009, the day the pandemic was declared by the World Health Organization, nine Western Pacific Region countries and areas had reported laboratory confirmed pandemic influenza A(H1N1) 2009 cases. From April 2009 to July 2010, more than 250 000 cases and 1800 deaths from laboratory-confirmed pandemic influenza A(H1N1) 2009 were reported from 34 countries and areas in the Region. By age group region-wide, 8.6%, 41.9%, 48.3%, and 1.2% of cases were in the < 5 years, 5-14 years, 15-64 years, and 65+ years age groups, respectively; the overall crude case fatality ratio in the Western Pacific Region was 0.5%. The pandemic demonstrated that region-wide disease reporting was possible. Countries and areas of the Western Pacific Region should take this opportunity to strengthen the systems established during the pandemic to develop routine disease reporting.
2009年4月28日，西太平洋区域报告了首例实验室确诊的2009年甲型H1N1大流行性流感感染病例。截至2009年6月11日世界卫生组织宣布大流行之日，西太平洋区域9个国家和地区报告了实验室确诊的2009年甲型H1N1大流行性流感病例。2009年4月至2010年7月，该区域34个国家和地区报告了超过25万例实验室确诊的2009年甲型H1N1大流行性流感病例和1800例死亡病例。按年龄组分，全区域<5岁、5-14岁、15-64岁和65岁以上年龄组的病例分别占8.6%、41.9%、48.3%和1.2%；西太平洋区域的总体粗病死率为0.5%。此次大流行表明全区域疾病报告是可行的。西太平洋区域各国和地区应借此机会加强在大流行期间建立的系统，以开展常规疾病报告。
