title: Survival from rabies encephalitis.
abstract: Rabies is a major public health problem in Asia and Africa, with nearly 60,000 deaths every year, and represents a substantial economic burden. Neurologists frequently encounter atypical cases, and need to make informed decisions regarding diagnosis and management. No therapy has been shown to unequivocally improve survival in rabies till date. Despite the overwhelmingly fatal nature of this disease, a small number of patients have been reported to survive acute rabies encephalitis with varying degrees of neurological sequelae. This paper presents the eleventh documented case of survival from rabies, which developed after being bitten by a stray dog, albeit with severe neurological residua. Similar to patients in previous reports, this man demonstrated a robust immune response as indicated by peripheral viral clearance and very high serum and cerebrospinal fluid antibody titres. Immunologically-mediated virus clearance therefore appears to be a prerequisite for survival. A detailed review of previously reported survivors, as well as descriptions of the host response and viral clearance in human rabies, current therapy for this disease and future directions in improving the currently dismal prognosis are provided.
