Herpes Simplex Encephalitis

Abstract
To learn more about the treatment of herpes simplex encephalitis with vidarabine, we conducted an uncontrolled study of 132 patients referred to 22 hospitals because of suspected disease. All had a brain biopsy and were started on vidarabine, but only 75 were diagnosed by isolation of virus from a brain-biopsy specimen. Cumulative mortality in the latter group was 39 per cent at one year.
