What typically is the most common cause of aseptic meningitis?

• A. Bacterial infection
• B. Viral infection, particularly enteroviruses
• C. Fungal infection
• D. Parasitic infection

Answer: (B)

The most common cause of aseptic meningitis is indeed viral infection, particularly enteroviruses. Aseptic meningitis refers to inflammation of the protective membranes covering the brain and spinal cord, which is typically not caused by bacteria. Enteroviruses are the primary culprits and are responsible for the majority of cases due to their prevalence and ability to affect the central nervous system. Other viruses, such as herpes simplex virus and mumps virus, can also be associated with aseptic meningitis but are less common than enteroviruses. In contrast, bacterial infections lead to a distinct condition known as bacterial meningitis, which is typically more severe and requires urgent treatment. Fungal and parasitic infections, while they can cause central nervous system issues, are rarer causes of meningitis compared to viral origins. Therefore, the prevalence and common occurrence of enteroviruses specifically make viral infections the leading cause of aseptic meningitis.
