[Population genetics of dengue virus and transmission of dengue fever].

The endemic behavior of dengue fever in Mexico during the past five years is of major concern to every sector related with public health and the effort to control the transmission has been focused on vector control. However, regardless of the effectiveness of the intervention measures it is important to know which elements determine dengue transmission. With regard to the molecular basis for dengue transmission, a great deal of progress has been made due to the introduction of genomic and bioinformatic approaches. The goal of this review is to describe the most recent developments in this area with emphasis on the Mexican situation.
