The BMJ predicted a rise in the number of asbestos related diseases.. teachers

Sunderland Echo, 11 Sep:The British Medical Journal recently predicted a rise in the number of asbestos-related diseases, likely to peak around 2020. The deadliest such disease is mesothelioma, for which there is no cure. Mesothelioma has mostly affected those who have worked in heavy industry without protection against the asbestos dust they were exposed to,” said Mr Hall. However, more recently cases have appeared where teachers and office workers have developed this disease.
These occupations were not previously considered at risk, but the evidence shows low level exposure to the dust is sufficient to cause disease.
