1. Disease etiology, prevention practices, treatment, and management
Etiology is the study of causes and origins of disease. Understanding why a disease develops helps guide prevention and treatment. Diseases may be caused by pathogens such as bacteria, viruses, parasites, or fungi; by environmental factors such as pollution, poor sanitation, and exposure to toxins; or by genetic predispositions that increase susceptibility. Lifestyle choices such as smoking, lack of exercise, and poor diet are also significant contributors.
Prevention practices operate on three levels. Primary prevention includes vaccinations, health education, sanitation, safe water supplies, and regular exercise to prevent diseases before they occur. Secondary prevention emphasizes early detection, such as cancer screenings or school vision and hearing tests, which allow for early intervention. Tertiary prevention focuses on managing chronic conditions to prevent complications, for example, teaching asthmatic students how to use inhalers properly or providing diabetic students with guidance on blood sugar monitoring.
