Who are more prone to meningitis?

Children between the ages of 1 month and 2 years are the most susceptible to bacterial meningitis. Adults with certain risk factors are also susceptible. You are at higher risk if you abuse alcohol, have chronic nose and ear infections, sustain a head injury or get pneumococcal pneumonia.

What drugs can cause non infectious meningitis?
