Which viral agent is commonly associated with meningitis?

Enteroviruses are a group of viruses that are well-known for causing viral meningitis, particularly in children. They primarily spread through the fecal-oral route and can lead to gastrointestinal symptoms, respiratory illnesses, and eventually, aseptic meningitis. This type of meningitis is characterized by an inflammatory response in the protective membranes covering the brain and spinal cord, often resulting in symptoms such as fever, headache, and neck stiffness.

While other viral agents like HIV and the influenza virus can cause neurological complications and affect the central nervous system, they are not the most common cause of viral meningitis. Rubella virus, primarily known for causing congenital defects and rashes, also does not typically present with meningitis. In the context of viral meningitis, enteroviruses are the predominant viral agents identified in epidemiological studies, making them the correct answer to the question.
