  1. Chapter 18 Noninfectious Diseases

  2. Chapter 18 Lesson 1 Disease and Disease Prevention Bellringer Explain the difference between infectious diseases and noninfectious diseases.

  3. Chapter 18 Lesson 1 Disease and Disease Prevention Objectives • Explainwhat a noninfectious disease is. • Explain the relationship between risk factors and noninfectious diseases. • Identify three strategies for preventing noninfectious diseases.

  4. Chapter 18 Lesson 1 Disease and Disease Prevention Start Off Write How might you get a disease that cannot be passed from person to person?

  5. Chapter 18 Lesson 1 Disease and Disease Prevention Noninfectious Diseases and Injuries • What Is a Noninfectious Disease?A noninfectious disease is a disease that is not caused by a virus or a living organism. • Types of Noninfectious Diseases Noninfectious diseases include immune system disorders, diseases of organs or systems, and nutrition disorders.

A risk factor is a characteristic or behavior that raises a person’s chances of getting a noninfectious disease. • Risk Factors You Can Control There are some risk factors, such as how much food you eat, that you can control. And in some cases, the risk factors you can control are the most important ones.
