To investigate the relative risk of occupational HIV transmission for surgeons practising in tropical Africa compared with their western colleagues.
From June to November 1993, a prospective study was performed at St Francis'Hospital, Katete, Zambia (350-bed hospital which serves a community of 300 000 people).
The HIV seroprevalence among consecutive surgical patients and the incidence of occupational parenteral exposures to blood during surgery were prospectively studied in a Zambian district hospital.
HIV seroprevalence was determined by taking blood from the surgical patients on admission into the operating theatre.
Serum was stored at - 20°C and transported to the Academic Medical Centre of the University of Amsterdam, where the presence of HIV antibodies was tested by enzyme immunoassay and seropositive samples confirmed by Western blot.
Although occupational exposure rate was relatively low, the HIV seroprevalence was so high that the relative cumulated seroconversion risk for surgeons in tropical Africa is estimated to be 1 5 times higher than in western countries.
This implies that health-care organizations should bear in mind that each year one out of 300 employees working in tropical Africa may become occupationally infected with HIV.
