What term describes diseases caused by physical injuries, genetic defects, or non-contagious factors?

The term that describes diseases caused by physical injuries, genetic defects, or non-contagious factors is non-infectious diseases. These conditions are characterized by their origins not being associated with pathogens like bacteria or viruses, distinguishing them from infectious diseases that spread from one individual to another. Non-infectious diseases can arise from various sources, including heredity, environmental exposure, lifestyle factors, and injuries. Examples include genetic disorders, certain types of cancer, and chronic conditions like cardiovascular diseases. Understanding this classification helps in recognizing how these diseases differ from infectious diseases and stresses the importance of prevention methods that are focused more on lifestyle and environmental factors rather than on exposure to infectious agents.
