Description
Introduction: Silica exposure is a substantial risk factor for TB disease: a recent systematic review1 found a pooled relative risk for TB in those with silicosis of 4.01 (95% CI 2.88 e 5.58). The TB risk was lower when silicosis was excluded. Infected workers can spread the disease to the general population; silica associated TB is thus a public health issue. This paper aimed to describe the burden of TB due to silica.
Materials and Methods: Literature was searched on excess TB burden due to silica exposure and on dust controls sufficient to reduce the TB risk to that of the general population.
Results: There is scant data on excess in TB cases due to silica. Reasons may be that numerator data are difficult to find as cases accumulate over the lifetime of the exposed subjects. The link to silica exposure may be missed and cases that arise in the community through contact with silica-associated patients are difficult to measure. The duration, nature and intensity of silica exposure that materially increases TB risk is unknown: for example, is cumulative exposure or short duration of intense exposure important, or both? Does the physical or chemical form of the silica moderate risk? No occupational exposure limits have formally considered TB in determining safe workplace concentrations.
Conclusions: The silica TB case burden is unknown. Numerous research questions exist, but the duration, nature and intensity of silica exposure that materially increases TB risk is key.
