登革热传播影响因素的研究进展

Advances in the study of the factors influencing dengue fever transmission

登革热是由登革病毒引起的、在全球范围广泛传播的急性蚊媒传染病。随着气候变暖,经济、贸易和旅游业的发展,近几十年全球登革热发病率大幅上升。每年登革热暴发流行给世界各国造成巨大的经济负担和公众健康威胁,这已成为全球重要公共卫生问题。本文系统地综述了蚊虫的种群密度、遗传因素、体内共生菌,登革病毒的血清型、株系、滴度,气候和社会环境等多种因素对登革热传播流行的影响,以期为登革热疫情的预测和防控提供理论参考。

Dengue fever is an acute mosquito-borne infectious disease caused by dengue virus that is found around the world. With global warming and the development of economics, trade, and tourism, the incidence of dengue fever has increased sharply in recent decades. Every year, outbreaks of dengue fever cause a huge economic burden and public health threat to most countries around the world, so dengue fever has become an important global public health issue. This paper systematically reviews the effects of mosquito population density, genetic factors, symbiotic bacteria, dengue virus serotype, strain, titer, climate, and social conditions on the prevalence of dengue fever in order to provide a theoretical reference to predict and prevent outbreaks.
