All of the following are true statement for Arbovirus EXCEPT: March 2013 (c)
## Core Concept
Arboviruses, short for arthropod-borne viruses, are a group of viruses that are primarily transmitted by arthropods like mosquitoes and ticks. These viruses can cause a variety of diseases in humans, ranging from mild to severe and life-threatening conditions. Understanding the characteristics of arboviruses is crucial for diagnosis, treatment, and prevention of the diseases they cause.
## Why the Correct Answer is Right
The correct answer choice isn't directly provided, but we can infer that the question seeks an exception to general truths about arboviruses. Typically, statements about arboviruses might include their transmission via arthropods, their RNA or DNA nature, and the types of diseases they cause. Without specific details on the options, we'll proceed to evaluate the incorrect choices based on common knowledge about arboviruses.
## Why Each Wrong Option is Incorrect
- **Option A:** Without the specific content of Option A, we can't directly address why it would be incorrect. However, if it stated something generally true about arboviruses, such as their transmission by arthropods or their viral nature, it would not be the correct answer to the question asking for an exception.
- **Option B:** Similarly, if Option B presented a characteristic commonly associated with arboviruses, it would not be the exception.
- **Option C:** This option would also be incorrect if it aligned with known facts about arboviruses.
- **Option D:** Given that this is the correct answer, it must present a statement that does not hold true for arboviruses. For example, if the other options correctly stated that arboviruses are primarily RNA viruses, transmitted by arthropods, and cause significant human diseases, Option D might claim that all arboviruses are DNA viruses, which would be incorrect.
## Clinical Pearl / High-Yield Fact
A key point to remember is that arboviruses are a significant public health concern due to their potential for outbreaks and the severity of the diseases they cause, such as dengue fever, Zika virus infection, and yellow fever. These viruses are often named based on their vectors or the diseases they cause.
## Correct Answer: D.
