Question

Which of the following is not a factor influencing preventive measures used to combat the spread of disease? A. Antibiotics B. Sanitation C. Behavior D. Cleanliness of food

Answer 1

C. Behavior

Although it does have some impact on the spread of disease, it is not a preventive measure to combat the spread of disease because it cannot be easily controlled.

EDIT: As my comment on the other answer states, this is incorrect. It is supposed to be a preventive measure, and antibiotics are not preventive, but behavior is.

Answer 2

The answer is A. Antibiotics. The reason is antibiotics is used to treat disease, not a preventative measure.
