甲型H1N1流感pdm09病毒一直是所有国家公共卫生监测系统面临的挑战。在塔那那利佛,于2009年8月12日报告了首例输入性病例。这项工作描述了甲型H1N1流感pdm09在马达加斯加的传播情况。利用哨点网络提供的通报数据,探讨了甲型H1N1流感pdm09在马达加斯加的传播情况。临床数据被绘制成图表,以确定每个哨点的峰值,并使用病毒学数据来确认病毒的循环。从2009年8月1日至2010年2月28日,报告了7427例流感样疾病患者。大多数患者年龄在7-14岁之间。实验室检测证实在750份标本中有237份(33.2%)感染了甲型H1N1流感病毒pdm09。患者的发病率在不同地区有所不同。通过确定疫情高峰,我们追踪了疫情在马达加斯加各地点和时间的传播情况。第一个高峰出现在塔那那利佛的47-2009年流行病学周期间,最后一个高峰出现在齐罗诺马曼迪迪的07-2010周。哨兵监测数据可用于描述流行趋势,促进在地方一级制定干预措施,以减轻疾病的传播和影响。
The influenza A(H1N1)pdm09 virus has been a challenge for public health surveillance systems in all countries. In Antananarivo, the first imported case was reported on August 12, 2009. This work describes the spread of A(H1N1)pdm09 in Madagascar. The diffusion of influenza A(H1N1)pdm09 in Madagascar was explored using notification data from a sentinel network. Clinical data were charted to identify peaks at each sentinel site and virological data was used to confirm viral circulation. From August 1, 2009 to February 28, 2010, 7,427 patients with influenza-like illness were reported. Most patients were aged 7 to 14 years. Laboratory tests confirmed infection with A(H1N1)pdm09 in 237 (33.2%) of 750 specimens. The incidence of patients differed between regions. By determining the epidemic peaks we traced the diffusion of the epidemic through locations and time in Madagascar. The first peak was detected during the epidemiological week 47-2009 in Antananarivo and the last one occurred in week 07-2010 in Tsiroanomandidy. Sentinel surveillance data can be used for describing epidemic trends, facilitating the development of interventions at the local level to mitigate disease spread and impact.
