What kind of diseases are labor diseases caused by occupational hazards?

Labor diseases caused by occupational hazards are specifically referred to as occupational diseases. These diseases are a direct result of exposure to harmful conditions or substances in the workplace. For instance, workers exposed to asbestos may develop asbestosis or lung cancer, while those who frequently work with chemicals may suffer from respiratory issues or skin conditions due to prolonged exposure.

Chronic diseases, while they may develop over time and can be related to workplace hazards, encompass a broader range of health issues that are not solely linked to occupational environments. Contagious diseases are infectious and spread from person to person, and they are unrelated to occupational exposure. Genetic disorders arise from inherited traits and are not caused by environmental factors in the workplace.

Thus, the term "occupational diseases" precisely captures the essence of health issues that are a direct result of specific occupational hazards, which is why it is the correct answer.
