Diagnosis of Human Rabies by the Cornea Test

Abstract

The second death due to rabies encephalitis occurring among American servicemen stationed in the Republic of Vietnam is reported. The clinical diagnosis was confirmed by performing the direct fluorescent antibody test for rabies on smears of corneal epithelial cells obtained on the second day of hospitalization. The reliability of various laboratory procedures in confirming the diagnosis of human rabies early in the course of clinical illness is discussed. The cornea test is a useful and rapid method of diagnosing human rabies prior to the development of significant serum antibody titers.
