【摘要】：目的通過時空聚集性分析方法,掌握2011-2015年陜西省腎綜合征出血熱(HFRS)發(fā)病情況的時空分布特征。方法收集"中國疾病控制信息系統(tǒng)"中2011-2015年陜西省各個縣(區(qū))HFRS報告數(shù)據(jù),采用Geoda1.6.7軟件進行空間全局和局部自相關分析,SatScan9.4.2軟件進行時空掃描,同時將相關分析結果使用ArcGIS 10.2軟件進行可視化地圖展示。結果 2011-2015年陜西省累計報告HFRS 10 026例,年均發(fā)病率為5.35/10萬,發(fā)病季節(jié)性呈現(xiàn)出明顯的雙峰特征(秋冬峰為10月至次年1月;夏季峰為6-7月),高發(fā)縣區(qū)集中在關中地區(qū);空間自相關結果顯示區(qū)域內(nèi)存在"高-高"(或熱點區(qū)域,主要分布于西安、寶雞和和咸陽)、"低-低"(或冷點區(qū)域,分布于延安、漢中、榆林和安康)等關聯(lián)模式的縣(區(qū));時空掃描分析探測到時間維度為2012年10月-2013年1月,空間維度覆蓋寶雞、咸陽和西安部分縣區(qū)的聚集區(qū)(RR=12.68,P0.001),聚集區(qū)在5年中位置相對固定。結論陜西省HFRS發(fā)病具有明顯的時空分布特征,關中地區(qū)為發(fā)病聚集區(qū)域,是HFRS的重點防控地區(qū)。
[Abstract]:Objective to study the spatial and temporal distribution of HFRS in hemorrhagic fever with renal syndrome (HFRS) from 2011 to 2015 in Shaanxi Province by means of spatio-temporal aggregation analysis. Methods the data of HFRS reports from counties (districts) in Shaanxi Province from 2011 to 2015 were collected from China Disease Control Information system. The spatial global and local autocorrelation analysis was carried out by Geoda1.6.7 software, and the results of correlation analysis were displayed using ArcGIS 10.2 software. Results 10,026 cases of HFRS were reported in Shaanxi Province from 2011 to 2015. The average annual incidence rate was 5.35 / 100 thousand. The seasonal incidence showed two peaks (from October to January in autumn and winter, June to July in summer, and concentrated in Guanzhong area in the county of high incidence. The spatial autocorrelation results show that there are "high and high" (or hot spots) in the region, mainly distributed in Xi'an, Baoji and Xianyang, "low-low" (or cold-point area, distributed in Yan'an, Hanzhong), Counties (regions) with associated models such as Yulin and Ankang; Spatio-temporal scanning analysis showed that the time dimension was from October 2012 to January 2013, and the spatial dimension covered Baoji. In Xianyang and some counties in Xi'an, the RRN 12.68 P0.001 was relatively fixed in the five years. Conclusion the incidence of HFRS in Shaanxi Province has obvious space-time distribution characteristics, Guanzhong area is the focus area of HFRS prevention and control.
