Abstract

The clinical spectrum of dengue fever ranges from asymptomatic infection to dengue shock syndrome. Although dengue is non-neurotropic virus, there is increasing evidence for dengue viral neurotropism suggesting there may be an element of direct viral encephalitis. Encephalopathy has been thought to result from the multisystem derangement that occurs in severe dengue infection, with liver failure, shock and coagulopathy causing a cerebral insult.  Dengue encephalitis is a rare disease. We report an interesting case of dengue encephalitis from Southern India. A 55 year male presented with headache, vomiting and altered sensorium. Dengue IgG/ IgM was positive. RTPCR for COVID was negative. Dengue encephalitis should be considered for differential diagnosis of fever with altered sensorium, especially in countries like India where dengue is rampant.

Keywords: Dengue fever, dengue encephalitis, neurological manifestations.
