What is Meningitis?
Meningitis is an infection that can lead to a dangerous swelling of the fluid surrounding the brain and spinal cord. The disease can be caused by either a virus or bacteria. Viral meningitis is generally less severe and resolves without specific treatment, while bacterial meningitis can be quite severe and may result in brain damage, hearing loss, learning disability, or death. About 2600 people get bacterial meningitis each year in the U.S. 10 to 15% of these cases are fatal, in spite of treatment with antibiotics. The disease can also cause permanent disabilities such as hearing loss, brain damage, seizures or amputation.
Why are college students at risk for Meningitis?
College students have a greater risk of bacterial meningitis infection than the general population because of activities that are often part of college life, such as living in residence halls, eating in dining halls and attending classes.
How is Meningitis transmitted?
Bacterial meningitis is transmitted through air droplets and direct contact with anyone already infected with the disease. The infection is spread through close contact with oral secretions, such as shared drinks, utensils and cigarettes, through coughing, or through intimate contact such as kissing.
What are the symptoms and when should I seek medical care?
Early symptoms of meningitis may include:
- High fever
- Severe headache
- Neck stiffness
- Sensitivity to light
Because the infection progresses rapidly, you should seek immediate medical care if 2 or more of these symptoms occur at the same time. If you are a Juniata student and have 2 or more of these symptoms at the same time, call 814.641-3636 without delay.
How long after exposure to meningitis will symptoms appear?
It's easy to mistake the early symptoms of bacterial and viral meningitis for the flu. These symptoms may develop over a period of 1 or 2 days, but some types of meningitis can prove fatal in a matter of hours. Even in less severe cases, the longer you delay getting treatment, the more likely you are to have permanent neurologic damage. Seek medical care right away if you or someone you know has any of the above symptoms.
How is it diagnosed?
Early diagnosis and treatment are very important. The diagnosis is usually made by growing bacteria from a sample of spinal fluid. The spinal fluid is obtained by performing a spinal tap, in which a needle is inserted into an area in the lower back where fluid in the spinal canal is readily accessible. Identification of the type of bacteria is necessary to prescribe the correct antibiotic treatment.
How is it treated?
Bacterial meningitis can be treated with a number of effective antibiotics. It is important, however, that treatment be started early in the course of the disease. Appropriate antibiotic treatment should reduce the risk of fatal meningitis to below 15%, although the risk is higher among the elderly.
Is it contagious?
Yes, some forms of bacterial meningitis are contagious. The bacteria are spread through the exchange of respiratory and throat secretions (i.e., coughing, kissing). People in the same residential unit, day care center, or anyone with direct contact with an infected person's oral secretions would be considered to be at increased risk of acquiring the infection. People who qualify as close contacts of a person with meningitis should receive antibiotics to prevent them from getting the disease. Fortunately, none of the bacteria that cause meningitis are as contagious as things like the common cold or the flu.
Can I prevent meningitis?
You can minimize your risk of bacterial meningitis by receiving a vaccine. The meningitis vaccine is generally safe and effective and is used for immunization against bacteria strains A, C, Y, and W-135, which account for about 70% of bacterial meningitis cases. At this time, it is unclear how long immunity lasts, so booster shots may be required in the future. As with any vaccine, not all individuals will be protected 100% after receiving the immunization.
