Abstract:

Silicosis and tuberculosis (TB) are significant mining related illnesses in developingcoun tries. The purpose of this study was to examine annual cases of these diseases in Zambian miners including comparison of periods before (1960–1970) and after (1992–2002) the arrival of the HIV/AIDS pandemic. The Occupational Health and Safety Research Bureau of Zambia reported 2,114 cases from 1945 to 2002. Of these, 22.7% were silicosis, 65.4% TB, and the remaining 11.9% silicotuberculosis. While silicosis cases decreased from 28.6% to 12.4% with the arrival of HIV/AIDS, there was a large increase in tuberculosiscases (37.1% to 86.1%), with a corresponding decrease in silicotuberculosis cases (34.3%. to 1.6%). Although silicosis remains an occupational health issue in Zambian miners, the. Most significant problem appears to be the marked increase in cases of TB.
