title: Outbreak of poliomyelitis in South Africa investigated by oligonucleotide mapping.
abstract: An outbreak of paralytic poliomyelitis, due to polio type 1 virus, occurred in the Gazankulu region of the Transvaal in the Republic of South Africa in 1982. Thirty-four different isolates from this epidemic were characterized by oligonucleotide mapping. None of the isolates were shown to be vaccine related. Results suggest the existence of a number of apparently different wild-type viruses present in the area. The introduction of a single wild-type strain could not be clearly demonstrated. These findings have important implications for the management and control of future outbreaks.
