The smoothed map of standardised incidence rates of dengue using kriging (Panel A) and a semi-variogram model (Panel B)

Dengue has been a major public health concern in Australia since it re-emerged in Queensland in 1992–1993. We explored spatio-temporal characteristics of locally-acquired dengue cases in northern tropical Queensland, Australia during the period 1993–2012.

Locally-acquired notified cases of dengue were collected for northern tropical Queensland from 1993 to 2012. Descriptive spatial and temporal analyses were conducted using geographic information system tools and geostatistical techniques.

登革热（Dengue）自1992—1993年在澳大利亚昆士兰州（Queensland）复现以来，始终是该国面临的重大公共卫生问题。本研究针对1993—2012年澳大利亚昆士兰州北部热带地区的本地感染登革热病例，探究其时空分布特征。
研究收集了1993至2012年昆士兰州北部热带地区的登革热本地感染报告病例数据，并采用地理信息系统（Geographic Information System，GIS）工具与地统计学技术开展描述性时空分析。
