Bacterial Meningitis

Bacterial Meningitis Disease Information

Meningitis is an inflammation of the covering of the brain and spinal cord--also called the meninges. It can be caused by viruses, parasites, fungi and bacteria. Viral (aseptic) meningitis is common; most people recover fully. Medical management of viral meningitis consists of supportive treatment and there is usually no indication for the use of antibiotics. Parasitic and fungal meningitis are very rare. Bacterial meningitis is very serious and may involve complicated medical, surgical, pharmaceutical, and life support management.

What are the symptoms?

Someone with meningitis will become very ill. The illness may develop over one or two days, but it can also rapidly progress in a matter of hours. Not everyone with meningitis will have the same symptoms.

Children (over 1 year old) and adults with meningitis may have:

  1. Severe headache

  2. High temperature

  3. Vomiting

  4. Sensitivity to bright lights

  5. Neck stiffness, joint pains

  6. Drowsiness or confusion

In both children and adults, there may be a rash of tiny, red-purple spots or bruises caused by bleeding under the skin. These can occur anywhere on the body. They are a sign of blood poisoning (septicemia), which sometimes happens with meningitis, particularly with the meningococcal strain.

How serious is bacterial meningitis?

If it is diagnosed early and treated promptly, the majority of people make a complete recovery. In some cases it can be fatal or a person may be left with a permanent disability such as deafness, blindness, amputations or brain damage (resulting in mental retardation or paralysis) even with prompt treatment.

How is bacterial meningitis spread?

Fortunately, none of the bacteria that cause meningitis are as contagious as diseases such as the common cold or flu, and they are not spread by casual contact or by simply breathing the air where a person with meningitis has been. The germs live naturally in the back of our noses and throats, but they do not live for long outside the body. They are spread when people exchange saliva (such as kissing; sharing drinking containers, utensils, or cigarettes).The germ does not cause meningitis in most people. Instead, most people become carriers of the germ for days, weeks or even months. Being a carrier helps to stimulate your body's natural defense system.
