报告人简介：阮士贵教授于1992年在加拿大阿尔伯特（Alberta）大学获得应用数学博士学位。1994-2002在加拿大道尔豪斯(Dalhousie)大学数学与统计系工作，先后任助理教授和副教授。从2002年起至今在美国迈阿密大学(University of Miami)数学系工作，并于2005年起任教授至今。阮士贵教授的主要研究领域是动力系统和微分方程及其在生物和医学中的应用，发表的论文的多达近两百篇，受到了国内外同行的关注与大量引用。阮教授对一些在传染病（如非典、乙型肝炎、血吸虫感染、狂犬病、疟疾、院内感染等）的数学建模、数据模拟和理论分析作了一系列开创性工作，这些工作不但填补了该领域的科研空白，而且对理解和控制这些传染病在我国的流行和传播有着非常重要的现实意义。阮教授担任生物数学领域重要期刊《Mathematical Biosciences》、《Discrete and Continuous Dynamical Systems - Series B》、《Mathematical Biosciences and Engineering》等重要期刊编委。

报告摘要：The ongoing Zika virus (ZIKV) epidemic poses a major global public health emergency as it has been reported in more than 60 countries worldwide, including ChinaandUSA. It is well-known that ZIKV is spread by Aedes mosquitoes, recent studies show that ZIKV can also be transmitted via sexual contact and cases of sexually transmitted ZIKV of the current outbreak have been confirmed in several countries. In this talk we first present a mathematical model to investigate the impact of mosquito-borne transmission and sexual transmission on prevention and control of ZIKV and use the model to fit the ZIKV data up to February2016 inBrazil,Colombia, andEl Salvador. Our result indicates that sexual transmission increases the risk of infection and epidemic size and prolongs the outbreak. Then we will introduce a second model to describe how Zika virus can be imported, established and spread in new territories by international travel. In order to prevent and control the transmission of ZIKV, it must be treated as not only a mosquito-borne disease but also a sexually transmitted disease.
