Practice question · Put in order
Order the three levels of prevention by when they intervene in a disease's natural course.
- Primary prevention: acts before the disease occurs at all.
- Tertiary prevention: acts after the disease is already established.
- Secondary prevention: acts early, after onset but before symptoms worsen.
Hints
- The ordering follows the disease's timeline from before onset onward.
- Before, then early, then after established.
Show the answer
- Primary prevention: acts before the disease occurs at all.
- Secondary prevention: acts early, after onset but before symptoms worsen.
- Tertiary prevention: acts after the disease is already established.
Why
The levels run primary (before onset), secondary (early detection), tertiary (after establishment) along the disease's natural course. Their names encode their position in that timeline, which is what makes them non-interchangeable.
