How many levels are there in infection control?

1. 2

2. 3

3. 4

4. 5

The correct answer is: 3

There are 3 levels in infection control, which are known as the "Hierarchy of Controls." These levels include administrative controls, engineering controls, and personal protective equipment. Option A, which suggests there are only 2 levels, is incorrect because it does not account for the important role of personal protective equipment in preventing the spread of infection. Option C, which suggests there are 4 levels, is incorrect because it adds an additional level that is not commonly recognized in the Hierarchy of Controls. Option D, which suggests there are 5 levels, is incorrect because it adds not one, but two additional levels that are not recognized in the standard Hierarchy of Controls. This makes option B the most accurate answer, as it correctly identifies the three established levels of infection control.
