英文摘要：

Dengue virus （DENV） is the pathogen of Dengue fever （DF）, which is a major public health prob- lem in tropical and sub-tropical regions and the most important arboviral disease of humans. In 2012, DF ranks as the most important mosquito-borne viral disease in the world. Fast and accurate diagnosis for DENV infection can effectively control the outbreak of DF and reduce death cases. Methods used for diagnosis of dengue infections include virus isolation, serology and molecular techniques. Each of three methods has its advantages and disadvantages, the suitable choice of methods in clinical practice should based on the clini- cal condition of patients.
