human diseases

Human diseases are medical conditions that affect the body's normal functions, often resulting from infections, genetic factors, environmental influences, or lifestyle choices. They can be classified into infectious diseases, caused by pathogens like bacteria and viruses, and non-infectious diseases, which include chronic conditions like diabetes and heart disease. Symptoms can vary widely, from mild discomfort to severe illness. Prevention often involves healthy living practices, vaccinations, and hygiene, while treatment may include medications, therapies, or lifestyle changes. Understanding diseases helps us maintain health and manage illness effectively.
