, different levels of disease prevention - Answer Primary
-aims to prevent disease or injury before it ever occurs. This is done by preventing exposures to
hazards that cause disease or injury, altering unhealthy or unsafe behaviors that can lead to
disease or injury, and increasing resistance to disease or injury should exposure occur
Secondary
-aims to reduce the impact of a disease or injury that has already occurred. This is done by
detecting and treating disease or injury as soon as possible to halt or slow its progress,
encouraging personal strategies to prevent re-injury or recurrence, and implementing programs
to return people to their original health and function to prevent long-term problems.

seatbelts and bike helmets)
-education about healthy and safe habits (e.g. eating well, exercising regularly, not smoking)
-immunization against infectious diseases.
example of secondary prevention - Answer -regular exams and screening tests to detect
disease in its earliest stages (e.g. mammograms to detect breast cancer)
-daily, low-dose aspirins and/or diet and exercise programs to prevent further heart attacks or
strokes
-suitably modified work so injured or ill workers can return safely to their jobs.
example of tertiary prevention - Answer -cardiac or stroke rehabilitation programs, chronic
disease management programs (e.g. for diabetes, arthritis, depression, etc.)
