The risk of pulmonary tuberculosis in underground copper

20151229&ensp·&enspPulmonary tuberculosis (PTB) among underground miners exposed to silica remains a global problem. Although well described in gold and coal mining, risk in other mining entities are not as well documented. This study aims to determine dustrelated dose response risk for PTB among underground miners exposed to silica dust in Zambia's copper mines.
