BACKGROUND
Dengue remains a major public health problem in the Philippines, particularly in urban areas of the National Capital Region. Thematic mapping using geographic information systems complemented by spatial analysis such as cluster analysis and hot spot detection can provide useful information to guide preventive measures and control strategies against dengue. Hence, this study was aimed to describe the spatiotemporal distribution of dengue incidence and identify dengue hot spots by barangay using reported cases from Quezon City, the Philippines from 2010 to 2017.
METHODS
Reported dengue case data at barangay level from January 1, 2010 to December 31, 2017 were obtained from the Quezon City Epidemiology and Surveillance Unit. The annual incidence rate of dengue from 2010 to 2017, expressed as the total number of dengue cases per 10,000 population in each year, was calculated for each barangay. Thematic mapping, global cluster analysis, and hot spot analysis were performed using ArcGIS 10.3.1.
RESULTS
The number of reported dengue cases and their spatial distribution varied highly between years. Local clusters were evident during the study period. Eighteen barangays were identified as hot spots.
CONCLUSIONS
Considering the spatial heterogeneity and instability of hot spots in Quezon City across years, efforts towards the containment of dengue can be made more targeted, and efficient with the application of hot spot analysis in routine surveillance. This may be useful not only for the control of dengue but also for other diseases, and for public health planning, monitoring, and evaluation.
背景
登革热仍是菲律宾的一个主要公共卫生问题，尤其是在国家首都地区的城市。利用地理信息系统进行专题绘图，并辅以聚类分析和热点检测等空间分析，可以提供有用信息，以指导登革热的预防措施和控制策略。因此，本研究旨在利用菲律宾奎松市2010年至2017年的报告病例，描述登革热发病率的时空分布，并按行政区识别登革热热点。
方法
从奎松市流行病学和监测部门获取2010年1月1日至2017年12月31日行政区一级的登革热报告病例数据。计算每个行政区2010年至2017年登革热的年发病率，以每年每10000人口中的登革热病例总数表示。使用ArcGIS 10.3.1进行专题绘图、全局聚类分析和热点分析。
结果
各年份报告的登革热病例数及其空间分布差异很大。在研究期间，局部聚类明显。18个行政区被确定为热点。
结论
考虑到奎松市各年份热点的空间异质性和不稳定性，在常规监测中应用热点分析，可使登革热防控工作更具针对性和高效性。这不仅可能对登革热的控制有用，对其他疾病以及公共卫生规划、监测和评估也可能有用。
