What is Meningitis
Meningitis is an inflammation of the membranes that cover the brain and spinal cord. People sometimes refer to it as spinal meningitis. Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment differ depending on the cause. Viral meningitis is generally less severe and clears up without specific treatment. But bacterial meningitis can be quite severe and may result in brain damage, hearing loss, or learning disabilities. For bacterial meningitis, it is also important to know which type of bacteria is causing the meningitis because antibiotics can prevent some types from spreading and infecting other people. Before the 1990s, Haemophilus influenzae type b (Hib) was the leading cause of bacterial meningitis. Hib vaccine is now given to all children as part of their routine immunizations. This vaccine has reduced the number of cases of Hib infection and the number of related meningitis cases. Today, Streptococcus pneumoniae (Pneumococcal Meningitis) and Neisseria meningitidis (Meningococcal Meningitis) are the leading causes of bacterial meningitis.
Bacterial Meningitis
How is bacterial meningitis diagnosed? A: Early diagnosis and treatment are very important. If symptoms occur, the patient should see a doctor immediately. 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 can be collected. Identification of the type of bacteria responsible is important for selection of correct antibiotics.
Can bacterial meningitis be treated? A: 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 of most common types of bacterial meningitis should reduce the risk of dying from meningitis to below 15%, although the risk is higher among the elderly.
Is bacterial meningitis contagious? A: Yes, some forms of bacterial meningitis are contagious. The bacteria can mainly be spread from person to person through the exchange of respiratory and throat secretions. This can occur through coughing, kissing, and sneezing. Fortunately, none of the bacteria that cause meningitis are as contagious as things like the common cold or the flu. Also, the bacteria are not spread by casual contact or by simply breathing the air where a person with meningitis has been. Some experts beleive smokers have a higher carrier rate and can expose their children to it.
However, sometimes the bacteria that cause meningitis have spread to other people who have had close or prolonged contact with a patient with meningitis caused by Neisseria meningitidis (also called meningococcal meningitis) or Hib. People in the same household or daycare center, or anyone with direct contact with a patient's oral secretions (such as a boyfriend or girlfriend) would be considered at increased risk of getting the infection. People who qualify as close contacts of a person with meningitis caused by N. meningitidis should receive antibiotics to prevent them from getting the disease. This is known as prophylaxis. Prophylaxis for household contacts of someone with Hib disease is only recommended if there is 1 household contact younger than 48 months who has not been fully immunized against Hib or an immunocompromised child (a child with a weakened immune system) of any age is in the household. The entire household, regardless of age, should receive prophylaxis in these cases.
Are there vaccines against bacterial meningitis? A: Yes, there are vaccines against Hib, against some serogroups of N. meningitidis and many types of Streptococcus pneumoniae. The vaccines are safe and highly effective.
The Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination of all persons 11-18 years of age with 1 dose of meningococcal conjugate vaccine at the earliest opportunity. Pre-teens who are 11-12 years old should be routinely vaccinated at the 11-12 year old check-up and again at age 16 and catch up at college age as recommended by ACIP. This visit is the best time for adolescents to receive meningococcal conjugate vaccine. Also, since the occurrence of meningococcal disease increases during adolescence, health-care providers should vaccinate previously unvaccinated pre-teens and teens 11-18 years of age with meningococcal conjugate vaccine at the earliest possible health-care visit.
College freshmen living in dormitories are at increased risk for meningococcal disease and should be vaccinated with meningococcal conjugate vaccine before college entry if they have not previously been vaccinated. The risk for meningococcal disease among nonfreshmen college students is similar to that for the general population of similar age (age 18-24 years). However, since the vaccines are safe and produce immunity, they can be provided to nonfreshmen college students who want to reduce their risk for meningococcal disease. Meningitis does not stop at the dorm room door. Please get vaccianted.
Routine vaccination also is recommended for certain persons who have increased risk for meningococcal disease. Use of meningococcal conjugate vaccine is preferred among people aged 2-55 years; however, use of meningococcal polysaccharide vaccine is recommended among adults over 55 years of age.
There are also vaccines to prevent meningitis due to S. pneumoniae (also called pneumococcal meningitis), which can also prevent other forms of infection due to S. pneumoniae. The pneumococcal polysaccharide vaccine (PPSV) is recommended for all persons over 65 years of age, younger persons at least 2 years old with certain chronic medical problems, and 19-64 year olds who smoke or have asthma. There is a vaccine (pneumococcal conjugate vaccine, or PCV13 ) that is effective in infants for the prevention of pneumococcal infections and is routinely recommended for all children younger than 2 years of age.
