title: Early central nervous system involvement in a young patient with dengue encephalitis.
abstract: A previously well 13-year-old boy presented with a short history of fever and altered mental status. His mother was admitted for dengue fever and there had been a recent dengue outbreak in their neighbourhood. He was diagnosed with dengue encephalitis as both his dengue non-structural protein 1 (NS-1) antigen and cerebrospinal fluid (CSF) dengue polymerase chain reaction (PCR) were positive. He did not have haemoconcentration, thrombocytopenia or any warning signs associated with severe dengue. He recovered fully with supportive treatment. This case highlights the importance of considering the diagnosis of dengue encephalitis in patients from dengue endemic areas presenting with an acute febrile illness and neurological symptoms.
