The global incidence of dengue fever is on the rise, especially in southeast Asia and the Americas. New research suggests much of this spread is caused by aeroplane travel. Researchers did a phylogenetic analysis of 2202 viral sequences from dengue virus samples collected in 20 countries between 1956 and 2015. They also assessed air travel, maritime mobility, migration, and socioeconomic factors for associated trends. Spread of dengue serotypes 1, 2, and 3 was associated with air travel more than any other factor.

研究简报

全球登革热的发病率正在上升，特别是在东南亚和美洲。新的研究表明，这种传播很大程度上是由飞机旅行引起的。研究人员对1956年至2015年间在20个国家/地区收集的登革热病毒样本中的2202个病毒序列进行了系统发育分析。他们还评估了航空旅行，海上机动性，迁移和社会经济因素的相关趋势。登革热血清型1、2和3的传播与航空旅行的关系比其他任何因素都多。
