Dengue virus can produce a wide spectrum of illnesses which include Dengue Fever (DF), Dengue Haemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS).This study is a retrospective analysis of various clinical manifestations of dengue fever with respect to its severity. The study was conducted in MVJ Medical College and Research Hospital, Hoskote from Aug. 2012 to Oct. 2012. An attempt was made to establish the role of serology and ultrasound in assessing the severity of dengue fever. Out of the 471 dengue patients, 141 had severe DF (88 had DHF, 53 had DSS) and 3 succumbed to death. The common clinical presentations were fever (100%), headache (95.7%), myalgia/arthralgia (92.1%), retro-orbital pain (78%), haemorrhagic manifestations (29.7%), respiratory distress (12.7%) and altered sensorium (4.5%) in that order. Only 50% of the patients with severe dengue showed positive serology. USG abdomen showing GB wall edema is a useful marker for early diagnosis of severe DF when associated with severe thrombocytopenia.
