For employees whose types of infectious diseases do not belong to the Classification and Catalogue of Occupational Diseases, as there is no explicit provision in the law, whether it is determined that there is a dispute over the issue of work injury makes it difficult for relevant employees to obtain work injury insurance relief The Work Injury Insurance Regulations protect employees who suffer accidental injuries or occupational diseases due to work. Occupational diseases, however, are listed by law in the Classification and Catalogue of Occupational Diseases, and there is very little room for legal interpretation. Meanwhile accident injuries are an uncertain legal concept, and there is considerable room for legal interpretation. The court's judgment on the case of disputes over the identification of work-related injuries among employees suffering from infectious diseases presents a path of thinking that includes employees suffering from infectious diseases as being injured by accidents. This study, through the implementation of the constitutional norms and values, combining the purpose of work-related injury insurance and the nature of work- related injury identification, and for the unified use of legal concepts and the resolution of conflicts between administrative legal norms, strongly argues that, by employing legal interpretation methods, infectious diseases can be included in the scope of interpretation of accident injuries, so as to resolve the dilemma of workers suffering from infectious diseases that work injuries cannot be relied upon.
