What might cause meningitis?

Meningitis is an inflammatory condition affecting the protective membranes covering the brain and spinal cord, and it can be caused by various pathogens. Meningococcal disease, caused by Neisseria meningitidis, is a well-known bacterial cause of meningitis. It can lead to severe infections, including meningitis, characterized by sudden onset of fever, headache, and stiff neck, instrumental in diagnosing the condition.

Pneumococcal disease, associated with Streptococcus pneumoniae, is another leading cause of bacterial meningitis. This bacterium can also cause pneumonia and bloodstream infections, but its role in meningitis is significant and well-documented.

While the flu virus primarily causes respiratory illness, it can also lead to viral meningitis, although this is less common than bacterial causes. The inclusion of both meningococcal and pneumococcal diseases in the answer underscores the recognition of these two predominant bacterial pathogens responsible for a majority of meningitis cases.

Choosing the option that includes both meningococcal and pneumococcal diseases acknowledges the serious nature of bacterial meningitis and highlights the importance of vaccination and public health efforts aimed at these infections.
