摘要
目的分析重庆市甲型H1N1流感疫情特征，提出防控措施建议。方法运用描述性流行病学方法，对重庆市2009年6～10月甲型H1N1流感疫情特征进行分析。结果6～10月共确诊甲型H1N1流感病例1531例，其中6～8月确诊22例，以散发的输入性病例为主，9～10月确诊1509例，以本土聚集性病例为主。疫情分布在除城口之外的39个区县，病例数居前几位的集中在主城区。10-20岁年龄组占病例总数的82．36％，性别比男：女=1．52：1，学生占病例总数的94．70％。6～10月哨点医院送检的3397份流感样病例标本中，流感阳性标本463份，其中甲型H1N1流感256份，占55．29％。结论进入9月份之后，尤其是国庆长假后，重庆市甲型H1N1流感疫情呈增速发展趋势，且由散发的输入性病例为主转为以本土聚集性病例为主。疫情从城市向农村逐渐扩散，城乡差距越来越小，未来一段时间农村地区甲型H1N1流感的防控形势严峻。随着疫情形势的不断加重，甲型H1N1流感防控存在两个重点，一是加强学校重点场所的防控力度，减少暴发疫情的发生；二是加强院内感染和高危人群的防控工作，防止重症和死亡病例的发生。
