Progress in the diagnosis of dengue virus infections and importance of point of care test: A Review

It is an urgent need of highly sensitive, specific and economical diagnostic tools for early and fast diagnosis of highly challenging dengue virus infections. Many laboratory methods including virus detection, genome detection, antigen detection and serological detection of such short-lived viremia were explored but promising outcomes for economical immunochromatographic tests have been reported in this review. With the trend of fast, easy operation, rapid diagnostic tests (RDT) based on immunochromatographic assays are of great importance due to point of care test (POCT) in the dengue endemic regions where it is short of laboratory equipments and cold storage conditions. Such kind of point of care diagnosis is more efficient, fast and user friendly. Moreover, the development of highly advance RDT is dependent on the use of anti-dengue monoclonal antibodies highly specific for particular analyte/antigen.
