Urbanization drives the epidemiology of infectious diseases to many threats and new challenges. In this research, we study the interplay between human mobility and dengue outbreaks in the complex urban environment of the city-state of Singapore. We integrate both stylized and mobile phone data-driven mobility patterns in an agent-based transmission model in which humans and mosquitoes are represented as agents that go through the epidemic states of dengue. We monitor with numerical simulations the system-level response to the epidemic by comparing our results with the observed cases reported during the 2013 and 2014 outbreaks. Our results show that human mobility is a major factor in the spread of vector-borne diseases such as dengue even on the short scale corresponding to intra-city distances. We finally discuss the advantages and the limits of mobile phone data and potential alternatives for assessing valuable mobility patterns for modeling vector-borne diseases outbreaks in cities.
城市化推动传染病的流行病学面临诸多威胁和新挑战。在这项研究中,我们研究了人类流动与新加坡城邦复杂城市环境中登革热爆发之间的相互作用。我们将刻板的和基于移动电话数据的移动模式集成到基于主体的传播模型中,在该模型中,人类和蚊子都被表示为经历登革热流行状态的主体。我们通过将结果与 2013 年和 2014 年爆发期间报告的实际病例进行比较,通过数值模拟监测系统对疫情的反应。我们的结果表明,即使在与城市内距离相对应的短期范围内,人类流动也是蚊媒传染病(如登革热)传播的主要因素。最后,我们讨论了移动电话数据的优势和局限性,以及评估城市中蚊媒传染病爆发建模的有价值的移动模式的潜在替代方法。
