■近年来,中国的麻疹发病率一直保持在每10万人中1人以下,然而,这种疾病尚未消除。本研究旨在综合分析2005-2022年麻疹流行病学特征,确定高危人群和地区,提出有针对性的干预措施。
■我们利用中国疾病预防控制信息系统的数据进行综合分析。空间自相关用于检查麻疹的空间聚类,而时空扫描分析用于检测时空聚类来描述研究期间的麻疹流行病学。
■从2005年到2022年,中国报告了732218例麻疹病例。总的来说,麻疹发病率呈下降趋势,特别是在2008-2011年和2015-2022年期间。2022年,发病率达到历史最低水平,为每10万人口0.039。麻疹主要影响幼儿。自2017年以来,全球空间集群有所减少,尽管热点地区仍然存在于西部省份。时空扫描确定了2005年至2008年的高发群,包括西部15个省,中央,和中国北部地区。相反,从2016年到2022年,在南部和中部省份发现了一个低发病率集群。
■中国在预防和控制麻疹方面取得了重大进展。最近的低发病率和没有实质性的时空聚集表明中国正在接近消灭麻疹。然而,继续需要加强西部省份幼儿和历史热点地区的预防和控制工作。此外,改善疫苗相关皮疹疾病的诊断至关重要.
UNASSIGNED: In recent years, the incidence of measles in China has consistently remained below 1 per 100,000 population, yet the disease has not been eliminated. This study aims to comprehensively analyze the epidemiological characteristics of measles from 2005 to 2022, identify high-risk populations and areas, and propose targeted interventions.
UNASSIGNED: We utilized data from the China Disease Prevention and Control Information System for our comprehensive analysis. Spatial autocorrelation was employed to examine the spatial clustering of measles, while
spatiotemporal scanning analysis was used to detect
spatiotemporal clustering to describe measles epidemiology during the study period.
UNASSIGNED: Between 2005 and 2022, 732,218 measles cases were reported in China. Overall, the incidence of measles exhibited a downward trend, particularly during the periods of 2008-2011 and 2015-2022. In 2022, the incidence rate reached its historical low at 0.039 per 100,000 population. Measles predominantly affects young children. Since 2017, global spatial clustering has diminished, although hotspot areas persist in the western provinces. Spatial-temporal scanning identified a high-incidence cluster from 2005 to 2008, comprising 15 provinces in the western, central, and northern regions of China. Conversely, from 2016 to 2022, a low-incidence cluster was detected in the southern and central provinces.
UNASSIGNED: China has made significant progress in measles prevention and control. The recent low incidence and absence of substantial
spatiotemporal clustering indicate that China is nearing measles elimination. However, there is a continuing need to enhance prevention and control efforts among very young children and in historic incidence hotspots in western provinces. Additionally, improving the diagnosis of vaccine-associated rash illnesses is essential.
