目的分析2006-2015年广州市恙虫病流行的时空分布特征,为疫情预报预警和防控提供时空线索支持。方法搜集并整理广州市2006-2015年恙虫病病例数据,对该数据进行性别、职业和年龄分组频数统计分析,并计算其发病率,描述广州市恙虫病发病时间分布和人群分布;运用ArcGIS 10.3软件将该病发病率用地图形式加以展现,描述其空间分布特征。结果 2006-2015年广州市恙虫病年平均发病率为4.42/10万,发病月份集中在6-11月,占全年发病总数的74.61%;发病人群主要集中在50~岁年龄组,广州市城市外缘地区的发病率明显高于城市中心区。结论广州市恙虫病发病率仍处于较高水平,并已形成明显的空间分布差异,应加强对高发区及高危人群的监测及防控。
Objective To analyze the spatial and temporal distribution characteristics of scrub typhus in Guangzhou from 2006 to 2015, and to provide spatial and temporal clues for the prevention and control of the epidemic. Methods The data of tsutsugamushi disease from 2006 to 2015 in Guangzhou were collected and analyzed. The data were analyzed by gender, occupation and age grouping frequency, and the incidence rate was calculated. The time and population distribution of tsutsugamushi disease in Guangzhou was described. Using ArcGIS 10.3 The software presents the incidence of the disease as a map and describes its spatial distribution. Results The average annual incidence rate of tsutsugamushi disease in Guangzhou was 4.42 / lakh from 2006 to 2015, and the incidence month was concentrated from June to November, accounting for 74.61% of the total in the whole year. The incidence was mainly in the 50 ~ age group, Guangzhou The outskirts of the city’s incidence was significantly higher than the city center. Conclusions The incidence of tsutsugamushi in Guangzhou is still at a high level, and the difference in spatial distribution has been formed. Monitoring and prevention and control of high-risk areas and high-risk populations should be strengthened.
