Define prevention and give two examples of behaviors that prevent illness or injury?

Prevention is an action taken as a precautionary measure to remain free of illness, injury or something bad happening. An example of prevention could be using helmets while riding bikes so that it prevents major injuries from happening. Secondly, maintaining a healthy diet can help you balance your hormones and save you from becoming obese.

Explanation:

Prevention has three stages, primary, secondary and tertiary. Primary prevention is an act of measures taken before the process of disease instigates. An example could be vaccination that is given to children to strengthen their immune system so they are capable enough to fight infectious diseases. Secondary prevention is done after early diagnosis of a disease, for instance examining breasts for breast cancer. Tertiary prevention is the rehabilitation process, it is the kind of prevention that does its best to cure a properly established disease. For instance chemotherapy is done to ensure cancer cells can be killed.
