The objectives of the occupational disease surveillance program (MCP) are to estimate the prevalence rates of occupational diseases, describe the occupational exposure agents associated with these conditions, and contribute to the assessment of underreporting of occupational diseases. For the 2013–2014 period, 29 physicians from the Lorraine region participated, representing 11% of the region’s occupational physicians. A total of 5,337 employees were seen during the 2013–2014 two-week reporting periods.
