Abstract：
Measles is a rapidly growing disease in the world with 869,770 cases and 207,500 deaths recorded in 2019. Niger continues to record epidemic outbreaks despite the actions taken. This study aims to analyze the national database from 2010 to 2019 to characterize the epidemiology of measles in Niger. This is a descriptive retrospective study. Our sample is exhaustive of suspected and positive measles cases from the database of the department of surveillance and response to epidemics for 10 years. Data extraction and analysis was done using Epi Info 7.2.3.1 software. In our study we found n=11,784 suspected measles cases notified from 2010 to 2019 with 37.2% of positive cases (IgM+). All regions are concerned. The female/male sex ratio was 1.1. The 1-to-5-year age group was the most representative (44.44%); 28.3% received at least one dose of vaccine; 62.22% lived in urban areas. The number of deaths was 225 (1.9%). The proportion of samples received at the laboratory within 3 days is 70.38%. The baseline analysis allowed us to find that all regions recorded cases and deaths with a low vaccination rate of 28.3%. Improved response and immunization strategies are recommended.
摘要：
麻疹是世界上一种快速增长的疾病，2019年记录了869,770例病例和207,500例死亡。尽管采取了行动，尼日尔仍继续记录疫情爆发。本研究旨在分析2010年至2019年的国家数据库，以描述尼日尔麻疹的流行病学特征。这是一项描述性回顾性研究。我们的样本从监测和流行病应对部门的数据库中穷尽了10年的疑似和阳性麻疹病例。使用EpiInfo7.2.3.1软件进行数据提取和分析。在我们的研究中，我们发现从2010年至2019年通报的n=11,784例疑似麻疹病例，其中37.2%的阳性病例(IgM+)。所有地区都受到关注。男女比例为1.1。1至5岁年龄组最具代表性（44.44%）；28.3%接种了至少一剂疫苗；62.22%生活在城市地区。死亡人数为225人（1.9％）。3天内实验室收到的样品比例为70.38%。基线分析使我们发现，所有地区都记录了28.3％的低接种率的病例和死亡。建议改善反应和免疫策略。
