The objective of this study was to define the clinical, immunological, and virological profiles of patients admitted to the General Hospital, Kandy with clinically apparent dengue. Demographic, clinical, hematological parameters, liver enzymes (ALT and AST), and blood samples were collected from 292 patients with fever &lt;5 days post onset and fulfilling the WHO criteria for the diagnosis of dengue fever\/dengue hemorrhagic fever (DF\/DHF). Samples were analyzed for, anti\u2010DENV IgM, IgG, and DENV nucleic acid. Myalgia was the commonest complaint by 65% of the patients. Packed cell volume was &gt;45% in 27% of the patients while 42.12% had reduced platelets and 62.67% had reduced white blood cell counts. In contrast to other studies, positive tourniquet test (PTT) and petechiae were not major indicators of DENV infection or severity of the disease. Clinical profiles were significantly different between DF and DHF\/DSS and showed many similarities to that reported elsewhere. Altogether, 43 patients (14.73%) were viremic as detected by RT\u2010PCR; 181 patients (62%) were positive for anti\u2010DENV IgM, and 245 (84%) patients were positive for anti\u2010DENV IgG. In combination, anti\u2010DENV IgM and RT\u2010PCR assays detected 224 (77.5%) of DENV infected cases, thus improving the DENV diagnosis rate. Hence, the diagnostic utility of PTT, anti\u2010DENV IgM\/IgG serology, or RT\u2010PCR used alone in the early phase of illness is low in Sri Lanka but the diagnostic value can be improved by a combination of serology and RT\u2010PCR. <jats:bold><jats:italic>J.
