RESUMO
The concern in all countries of occupational health has led to the study of occupational risk factors and their impact on health. But maintaining the health of workers is increasingly complex, especially in occupational allergic diseases, which have increased in parallel with the increased use in industries of potentially irritating chemicals or allergens, leading to skin or respiratory sensitization. Diseases arising from these immunological substances are classified by Spanish Legislation as occupational diseases, as set out in Royal Decree 1299/2006, of November 10, 2006 (Group 1, Group 4 and Group 5). The most important ones in occupational medicine are allergic respiratory diseases and dermatological allergic diseases, although there are other allergies of interest, such as those involving mucous membranes (allergic eye diseases). A joint collaboration between the different medical disciplines involved to improve prevention at work is highly desirable.
