All are caused by common vectors, except
**Core Concept**
The question pertains to the identification of diseases caused by common vectors. Vectors are organisms that transmit disease-causing pathogens to humans. Common vectors include mosquitoes, ticks, and sandflies.
**Why the Correct Answer is Right**
The correct answer is determined by identifying diseases that are not typically transmitted by the same vectors. For example, diseases like malaria and dengue fever are transmitted by mosquitoes, while tick-borne illnesses like Lyme disease and Rocky Mountain spotted fever are transmitted by ticks. Sandflies are responsible for transmitting leishmaniasis.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a disease caused by a vector.
**Option B:** This option is incorrect because it is not a disease caused by a common vector, or it is a disease caused by a vector that is not typically associated with the other options.
**Option C:** This option is incorrect because it is a disease caused by a common vector.
**Option D:** This option is incorrect because it is a disease caused by a common vector.
**Clinical Pearl / High-Yield Fact**
It's essential to recognize the primary vectors associated with various diseases to implement effective prevention and control measures. Understanding the vectors responsible for disease transmission can help public health officials target interventions and educate the public about risk reduction strategies.
**Correct Answer:** D.
