A survey of zoonotic diseases contracted by South African veterinarians.
A survey of 88 veterinarians employed at the Faculty of Veterinary Science, University of Pretoria, South Africa, was carried out to investigate the occurrence of zoonotic diseases among South African veterinarians. The survey found that 63.6% of veterinarians interviewed had suffered from a zoonotic disease. Veterinarians predominantly involved in farm animal practice were 3 times more likely to have contracted a zoonotic disease than those working in other veterinary fields. Fifty-six percent of disease incidents were initially diagnosed by the veterinarians themselves. Fifty-three percent of incidents required treatment by a medical practitioner, but the majority (61%) of incidents did not require absence from work. The incidence density rate for contracting a zoonotic disease was 0.06 per person year of exposure. Kaplan-Meier survival analysis estimated that the probability of having contracted a zoonotic disease was 50% after 11 years in practice. The risk of contracting a zoonotic disease appeared to be higher early in practice. The most common mode of transmission was by direct contact. Approximately 46% of South Africans still live in rural areas and regularly come into close contact with farm animals. The implications of this in the light of this survey's results are discussed.
