The public health nurse understands that which of the following is an example of a vector borne disease?
Correct answer
B
Rationale
The correct answer is B: Rocky Mountain spotted fever. This is a vector-borne disease because it is transmitted to humans through the bite of an infected tick. Ticks act as vectors by carrying and transmitting the bacteria that causes the disease. Hepatitis B, E. coli 0157:H7, and Anthrax are not vector-borne diseases; they are transmitted through other means such as contaminated food or water, bodily fluids, or spores respectively. Therefore, B is the only choice that fits the definition of a vector-borne disease.
