Health and Diseases
Understanding health and diseases, including causes and prevention, helps us maintain wellness and protect against illness effectively.
Core concept
Diseases can be classified as communicable (spread between people, like flu) or non-communicable (not spread, like diabetes).
How it works
Pathogens like bacteria, viruses, fungi, and parasites cause communicable diseases, spreading through various means like air, water, or contact.
Why it matters
Non-communicable diseases often result from lifestyle factors, genetics, or environmental factors, like heart disease or diabetes.
Key detail
Prevention strategies, including vaccination, hygiene, healthy diet, and exercise, help reduce the risk of both types of diseases.
