ICD-11 1F00.21 — Encephalitis due to herpes simplex virus
Herpetic encephalitis is a cerebral infection caused by herpes simplex virus type 1 (HSV1). It presents as acute necrosing temporal encephalitis. Onset is rapid (less than 48 hours) with a fever of 40C, headaches, and behavioural, language and memory problems. These initial manifestations are followed by numbness and coma, which may be accompanied by convulsions and paralysis. This disease, which affects only a small minority of HSV1-infected individuals, results from a primary immune deficiency.
