What is meningitis?

Bacterial vs. Viral meningitis

It's very important for doctors to identify whether the infection is viral or bacterial; they can determine this only through analysis of the spinal fluid. Most cases of meningitis are caused by a viral infection, which is serious but only rarely fatal in people with normal immune systems.

Bacterial meningitis, on the other hand, is much more severe. It often results in brain damage, hearing loss, long-term learning disabilities or death. Early diagnosis of bacterial meningitis is key, because it progresses so rapidly and can cause such significant damage in a matter of hours. A patient experiencing the symptoms of bacterial meningitis should seek medical advice immediately.

who gets meningitis?

Meningitis doesn't discriminate; anyone of any age can contract this infection. Particularly vulnerable are pre-teens and adolescents; people who live in dorms, prisons and other community settings; and people who travel to countries where meningitis is widespread. Additionally, people who are pregnant, are immuno-compromised or work with domestic animals are at higher risk of contracting meningitis.

Prevention

Following the recommended meningitis vaccination schedule is crucial for children and other groups at high risk.

Complications of meningitis can be very severe. If you think that you or someone you know may be infected, it's crucial to get to a doctor or hospital right away. The longer the disease goes untreated, the greater risk of permanent neurological damage. Meningitis is often life threatening, so remember: Vaccination and early detection are key.
