Abstract

Ecuador in the northwestern edge of South America is struggling by vector-borne diseases with an endemic-epidemic behavior leading to an enormous public health problem. Malaria, which has a cyclicality in its dynamics, is closely related to climatic, ecological and socio-economic phenomena. The main objective of this research has been to compare three different prediction species models, the so-called Maxent, logistic regression and multi criteria evaluation with fuzzy logic, in order to determine the model which best describes the ecological niche of the Anopheles spp species, which transmits malaria within Ecuador. After performing a detailed data collection and data processing, we applied the mentioned models and validated them with a statistical analysis in order to discover that the Maxent model has been the model that best defines the distribution of Anopheles spp within the territory. The determined sites, which are of high strategic value and important for the increasing national development, will now be able to initiate preventive countermeasures based on this study.

摘要

位于南美洲西北边缘的厄瓜多尔正饱受媒介传播疾病之苦,这些疾病呈现地方病-流行病特征,导致了巨大的公共卫生问题。疟疾在其动态变化上具有周期性,与气候、生态和社会经济现象密切相关。本研究的主要目的是比较三种不同的预测物种模型,即所谓的最大熵模型(Maxent)、逻辑回归模型和基于模糊逻辑的多标准评价模型,以确定最能描述在厄瓜多尔传播疟疾的按蚊属物种生态位的模型。在进行详细的数据收集和数据处理后,我们应用了上述模型并用统计分析进行验证,结果发现最大熵模型是最能界定按蚊属在该地区分布的模型。这些具有高度战略价值且对国家发展日益重要的已确定地点,现在将能够基于本研究启动预防对策。
