Their median age was 33 (range 7–65) years; of the 45 patients, 39 were adults (87%) and only 6 were below 18 years of age. Twenty-three (51%) had DF, 15 (33%) had DHF and 7 (16 %) had DSS.All the patients had fever as the presenting complaint; the median duration of fever was 6 (range 1–13) days.

On examination, 11 (24%) patients had hepatomegaly, 9 (20%) had clinically detectable ascites and 7 (16%) had jaundice.The median platelet count was 34x109/L (range 9–99x109/L). Liver function tests revealed ALT and AST elevation in 43 patients (96%) each, hyperbilirubinaemia (>2 mg/dl) in 12 of 40 patients (30%) and hypoalbuminaemia (32 seconds) was prolonged in 2 of 29 patients (7%).
