## **Core Concept**
Enteroviruses are a group of viruses that belong to the **Picornaviridae** family. They are commonly associated with a variety of clinical syndromes, including **aseptic meningitis**, **encephalitis**, **myocarditis**, **pericarditis**, and **hand, foot, and mouth disease**. These viruses are highly contagious and spread primarily through the fecal-oral route.

## **Why the Correct Answer is Right**
The correct answer, **D. Rabies**, is not caused by an enterovirus. Rabies is caused by a virus from the **Lyssavirus** genus, which is a distinct viral family separate from the **Picornaviridae** family to which enteroviruses belong. Enteroviruses are known to cause a range of diseases, but rabies is not among them.

## **Why Each Wrong Option is Incorrect**
- **Option A:** **Poliomyelitis** is indeed caused by an enterovirus, specifically **poliovirus**, which is a type of enterovirus. Therefore, this option is incorrect as an "except" answer.
- **Option B:** **Hand, foot, and mouth disease** can be caused by several types of enteroviruses, including **coxsackievirus A** and **enterovirus 71**. This makes it an incorrect choice for an "except" question.
- **Option C:** **Aseptic meningitis** can also be caused by enteroviruses, among other viruses. Enteroviruses are a common cause of viral (aseptic) meningitis, especially in children. This option is therefore incorrect.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that enteroviruses are a common cause of **viral myocarditis** and **pericarditis**, particularly in young adults. They are also notable for causing outbreaks of **hand, foot, and mouth disease** in children.

## **Correct Answer:** D. Rabies
