In April 2009, the World Health Organization (WHO) declared pandemic influenza A (H1N1) "public health emergency of international concern". On June 11, 2009, WHO raised the pandemic alert level to phase 6, indicating a global pandemic. By December 2009, more than 208 countries and territories had reported swine flu cases. The descriptive epidemiology of the first reported 100 cases of this virus in Saudi Arabia are summarized in this report.
Data were collected from 1 June to 3 July, 2009 using a predesigned questionnaire. Questionnaires were filled by Field Epidemiology Training Program residents. Data for the first 100 complete cases of confirmed pandemic influenza A (H1N1) were compiled and analyzed.
The age of reported cases was in the range of 1 to 56 years. The highest percentage of cases was in the age group of 20 to 30 years followed by the age group of 1 to 10 years. Females represented 55% of the cases; imported cases represented 47%, 58% of whom had come via the King Khaled Airport. The most common nationalities most were from Saudi Arabia and the Philippines. The main symptoms were fever (56%), cough (54%), and sore throat and the number of cases was seen to peak from the 27 to 29 June.
Pandemic influenza A (H1N1) is still a threat to Saudi Arabia. Thus, comprehensive and effective measures for surveillance and prevention of the disease are needed to control its spread.
2009年4月，世界卫生组织（WHO）宣布甲型H1N1流感为“国际关注的突发公共卫生事件”。2009年6月11日，WHO将大流行警戒级别提升至6级，表明已出现全球大流行。截至2009年12月，超过208个国家和地区报告了猪流感病例。本报告总结了沙特阿拉伯首次报告的100例该病毒病例的描述性流行病学情况。
采用预先设计的问卷收集2009年6月1日至7月3日的数据。问卷由现场流行病学培训项目的学员填写。对确诊的甲型H1N1流感大流行的前100例完整病例的数据进行汇总和分析。
报告病例的年龄在1至56岁之间。病例数占比最高的年龄组为20至30岁，其次是1至10岁年龄组。女性占病例的55%；输入性病例占47%，其中58%经由哈立德国王机场入境。最常见的国籍是沙特阿拉伯和菲律宾。主要症状为发热（56%）、咳嗽（54%）和咽痛，病例数在6月27日至29日达到峰值。
甲型H1N1流感大流行对沙特阿拉伯仍是一种威胁。因此，需要采取全面有效的监测和预防措施来控制其传播。
