**Core Concept**
Aseptic meningitis, also known as viral meningitis, is an inflammation of the protective membranes (meninges) covering the brain and spinal cord, not caused by bacterial infection. The condition is usually caused by viral infections, although other pathogens like fungi and parasites can also be responsible.

**Why the Correct Answer is Right**
The most common cause of aseptic meningitis is an enteroviral infection, typically transmitted through the fecal-oral route. The virus enters the body through contaminated food, water, or contact with an infected person's feces. Once inside the body, the virus replicates in the gastrointestinal tract and eventually spreads to the central nervous system (CNS), causing inflammation of the meninges.

**Clinical Pearl / High-Yield Fact**
Aseptic meningitis is often confused with bacterial meningitis, which has a more severe presentation and requires prompt antibiotic treatment. However, the two conditions have distinct differences in terms of their symptoms, laboratory findings, and treatment approaches. A key distinguishing feature is the elevated cerebrospinal fluid (CSF) glucose level in aseptic meningitis.
