Which tick is commonly associated with both Rocky Mountain spotted fever and Lyme disease?

The correct answer indicates that none of the listed tick species are commonly associated with both Rocky Mountain spotted fever and Lyme disease. Understanding the associations between specific ticks and the diseases they carry is essential for effective prevention and public health education.

Rocky Mountain spotted fever is primarily transmitted by the American dog tick and also the Rocky Mountain wood tick, while Lyme disease is most often associated with the deer tick or black-legged tick. The confusion may arise because of the overlap in names; however, neither of the first two choices listed, nor the Rocky Mountain wood tick, is a carrier of both diseases simultaneously.

This question highlights the importance of distinguishing between tick species and the specific diseases they transmit for accurate diagnosis and effective prevention measures in the context of tick-borne illnesses.
