The diagnosis of occupational diseases should be made by specialist physicians in occupational medicine with systematic professional assessment to determine whether there is a causal relationship between the diseases suffered by the workers and their work, with reference to the Guideline of Identification and Recognition of Occupational Diseases and the Principles for Diagnosis of Occupational Diseases.
