An estimated 49·5 million small-scale miners worldwide are exposed to high concentrations of silica during their work. The substantial morbidity and mortality of silicosis and tuberculosis among workers exposed to such intensities have been documented. This Viewpoint raises concern at the failure to respond to a growing epidemic of lung disease (predominantly silicosis and tuberculosis) among small-scale miners.

Occupational exposures are a common and preventable cause of lung disease. About 1 in 6 cases of COPD and asthma worldwide are related to work.

Early recognition of occupational lung disease improves outcomes. Doctors should ask about work history in patients with respiratory symptoms. This educational review article briefly outlines key clinical features, relevant to the general physician, of common occupational lung diseases seen in the UK. These conditions include work-related asthma, pneumoconioses, hypersensitivity pneumonitis and COPD.
