Which of the following group of virus is most likely involved in viral meningitis –
**Core Concept**
Viral meningitis is an inflammation of the protective membranes covering the brain and spinal cord, known as the meninges, caused by a viral infection. The most common causes of viral meningitis are enteroviruses, which include **coxsackieviruses**, **echoviruses**, and **polioviruses**. These viruses are highly contagious and typically spread through the fecal-oral route.
**Why the Correct Answer is Right**
The correct answer is related to enteroviruses, which are a common cause of viral meningitis, especially in children. These viruses can infect the meninges, leading to inflammation and the symptoms associated with meningitis. The mechanism involves the virus replicating in the gastrointestinal tract before spreading to the central nervous system.
**Why Each Wrong Option is Incorrect**
**Option A:** Is incorrect because it does not specify the correct group of viruses associated with viral meningitis.
**Option B:** Incorrect as it is not directly linked to the most common cause of viral meningitis.
**Option C:** This option is incorrect as it is less commonly associated with viral meningitis compared to the correct answer.
**Option D:** Incorrect because, although it could be a cause of meningitis, it is not the most likely group involved in viral meningitis.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that enteroviruses are the most common cause of viral meningitis, and their diagnosis is often clinical, with treatment being largely supportive.
**Correct Answer:** D. Enteroviruses.
