One of the key ways to classify diseases is through the lens of their causes and impacts on health. For example, congenital and hereditary diseases often stem from genetic factors and can manifest at birth or develop later, leading to long-term health implications. Meanwhile, infectious diseases are caused by pathogens like bacteria, viruses, or parasites, and can spread from person to person or through environmental exposure.

When it comes to real-world applications, understanding these classifications is vital for healthcare professionals. For example, tracking infectious diseases has been crucial in managing public health responses during outbreaks, while knowing about degenerative diseases can inform treatment approaches for chronic conditions. This knowledge not only helps in patient care but also plays a crucial role in research and policy-making.
