2EPIDEMOLOGY OF DENGUE VIRUS INFECTIONDiagnosis of the dengue virus in the plasma serum, blood, CSF of brain and other bodyfluids by using polymerase chain reaction.Isolation of the DENV by the cell culture of the plasma of the serum or the specimen ofCSF.Identification of the IgM anti DENV by immunoassay of the serum specimen.Identification of the DENV antigen in the immune fluorescence assay. Identification of IgM anti-DENV by the immunoassay in the serum or CSF in a personwho stays in an area that is dengue endemic or non-endemic or recent vaccination againsta flavivirus.2010 Case definition of dengue virus infectionsClinical DescriptionIt is an acute feverish illness that is characterized by retro-ocular pain, frontal headache, pain inmuscles and joints, followed by rashes.
