Data from: The impact of weather and storm water management ponds on the transmission of West Nile virus

West Nile virus (WNV) is the most widely distributed arbovirus in the world and the spread is influenced by complex factors including weather conditions and urban environmental settings like storm water management ponds (SWMP). The purpose of this work was to develop an ordinary differential equation model to explore the impacts of SWMP, temperature and precipitation on WNV vector abundance and the transmission of WNV between mosquito and bird populations. The model was used to analyse how weather conditions and SWMP can influence the basic reproduction number. The results found that an excess of precipitation and fiercer intraspecific competition will reduce vector population and the peak value of infectious vectors and birds. This information can be used to identify measures that would be useful to control larval abundance in SWMP and the transmission of WNV.

西尼罗河病毒（West Nile virus, WNV）是全球分布最为广泛的虫媒病毒（arbovirus），其传播受到气象条件、雨水管理塘（storm water management ponds, SWMP）这类城市环境在内的多种复杂因素影响。本研究旨在构建常微分方程（ordinary differential equation）模型，以探究雨水管理塘（SWMP）、气温与降水对西尼罗河病毒媒介种群丰度，以及蚊、鸟种群间西尼罗河病毒传播的影响。该模型被用于分析气象条件与SWMP对基本再生数（basic reproduction number）的调控作用。研究结果显示，过量降水与更剧烈的种内竞争会降低媒介种群规模，以及感染性媒介与鸟类的种群峰值。本研究成果可用于识别可有效管控SWMP中幼虫丰度与西尼罗河病毒传播的防控措施。
