Herpes simplex encephalitis: analysis of a cluster of cases by restriction endonuclease mapping of virus isolates.
In December 1979, there were three deaths from culture-proven herpes encephalitis in 3 weeks in the New Haven area, and a nurse caring for one of these patients developed a herpetic lesion on her nose. The three brain isolates, the isolate from the nurse, and several epidemiologically unrelated strains were analyzed by restriction endonuclease mapping. All were determined to be distinct strains of herpes simplex virus. The possibility that a single strain of virus caused this cluster of cases was therefore examined directly and disproved.
