- Abstract: Dengue is the fastest spreading,mosquito-borne viral infectious disease worldwide,with remarkable morbidity and mortality.In the past decades,profound contributions have been made towards understanding its epidemiology,including disease burden and distributions,risk factors,and control and prevention practices.Dengue continues to disseminate to new areas,including high latitude regions,and a new serotype (dengue virus serotype 5) has been identified.Vaccine research has made new progress,in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment.In disease surveillance,because of its operational simplicity,rapidity,capability,and utility as an indicator of disease severity,dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions.Vector control progress has driven new breakthroughs in biotechnology,including Wolbachia-infected Aedes and genetically modified Aedes.Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression.In the future,vector control should still be pursued as a key measure to prevent transmission,along with anti-viral drug and vaccine research.
