The MCP surveillance program relies on the voluntary participation of occupational physicians in the region and their teams, who report all MCPs encountered during their consultations with employees twice a year, over two consecutive two-week periods known as "MCP fortnights." The MCP surveillance program, launched in Guadeloupe and Martinique in 2018, continued in 2019. This brochure presents the cumulative results of the two-week periods conducted in 2018 and 2019 in Guadeloupe and Martinique.
