The 1992 foot-and-mouth disease epizootic in the Kruger National Park.

The monitoring of a foot-and-mouth disease epizootic amongst impala (Aepyceros melampus) in the Kruger National Park is described. Infection rates of different sex and age classes of impala within the outbreak focus were determined. Seroprevalence rates in other clovenhoofed species were also determined. RNA sequencing of a portion of the 1D gene of viruses isolated from SAT-2 viruses obtained from diseased impala showed that they were unrelated to previous SAT-2 isolates made from animals in the Kruger National Park.
