The first factor was transport related, which is primarily a measure of the rapidity of sending samples to the national laboratory. However, this factor is also a measure of internal movement control, active and passive surveillance and effectiveness of contacting the contiguous provinces and the national veterinary services in an outbreak situation. As one variable increases, the other variables tend to increase correspondingly; thus, a failure in any one of the factors Note: It should be noted that differential capacities exist between the provinces and certain provinces have significant strength in animal disease surveillance compared with others. The outcomes of the survey represent the overall mix of all opinions amongst the provinces, based on the subjects' willingness to participate. Regularity of abattoir visits varies amongst provinces. Certain provinces have organised the veterinary services in a way to separate the Veterinary Public Health Section/Unit, who pay more regular visits to the abattoir within such provinces. Important endemic diseases in certain locations include: ASF, erysipelosis, sarcoptic mange, leptospirosis, bacteria septicaemia, production and management diseases and Taenia solium, in that order. It should be noted that ASF is not endemic in all parts of South Africa, but is restricted to the control zones within KwaZulu Natal, Mpumalanga, Limpopo and the North West. Mid p-exact percentages and ranges were calculated at 95% confidence interval (95% CI).
