Meningitis: Infections
built 633 days ago
Meningitis is an infection that occurs in the spinal fluid, and it can be caused by a virus or bacterium, according to the U.S. Centers for Disease Control and Prevention. The bacterial forms of meningitis tend to be more serious, potentially causing brain damage, hearing loss and learning disabilities. Two vaccines -- the Haemophilus influenza (Hib) and pneumococcal -- can protect youngsters, including babies, against certain strains of bacterial meningitis, but not all. Two other vaccines offer protection against four strains of the Neisseria meningitidis bacteria -- one for children aged 2 to 10 and the other for those aged 11 and up -- but neither offers protection to babies.

Meningitis and encephalitis are usually caused by viruses or bacteria. Most often, the body’s immune system is able to contain and defeat an infection. But if the infection passes into the blood stream and then into the cerebrospinal fluid that surrounds the brain and spinal cord, it can affect the nerves and travel to the brain and/or surrounding membranes, causing inflammation. This swelling can harm or destroy nerve cells and cause bleeding in the brain.
