How Is Meningitis Diagnosed?
Bacterial meningitis can be very serious. So if you see symptoms or think that your child could have meningitis, it's important to see the doctor right away.
If meningitis is suspected, the doctor will order tests, probably including a lumbar puncture (spinal tap) to collect a sample of spinal fluid. This test will show any signs of inflammation and whether the infection is due to a virus or bacteria.
How Is Meningitis Treated?
Most cases of viral meningitis end within 7 to 10 days. Some people might need to be treated in the hospital, although kids usually can recover at home if they're not too ill. Treatment to ease symptoms includes rest, fluids, and over-the-counter pain medicine.
If bacterial meningitis is diagnosed — or even suspected — doctors will start intravenous (IV) antibiotics as soon as possible. Fluids may be given to replace those lost to fever, sweating, vomiting, and poor appetite.
What Problems Can Happen?
Complications of bacterial meningitis might require further treatment. Someone with shock or low blood pressure might get more IV fluids and medicines to increase blood pressure. Some kids may need extra oxygen or mechanical ventilation if they have trouble breathing.
Bacterial meningitis complications can be severe and include neurological problems, such as hearing loss, visual impairment, seizures, and learning disabilities. Because impaired hearing is a common complication, those who've had bacterial meningitis should have a hearing test after they recover.
The heart, kidneys, and adrenal glands also might be affected, depending on the cause of the infection. Although some kids develop long-lasting neurological problems, most who receive prompt diagnosis and treatment recover fully.
Can Meningitis Be Prevented?
Vaccinations
Routine immunization can go a long way toward preventing meningitis. The Hib, measles, mumps, polio, and pneumococcal vaccines can protect against meningitis caused by those germs.
Kids also should get the meningococcal conjugate vaccine when they're 11 or 12 years old, with a booster shot at age 16. Kids older than 11 who haven't been vaccinated also should be immunized, particularly if they're going to college, boarding school, camp, or other settings where they'll live in close quarters with others.
A newer type of meningococcal vaccine called MenB (which protects against a type of meningococcal bacterium not covered by the older vaccine) can be given to teens and young adults at the discretion of their doctor.
Avoiding Germs
Kids and adults should wash their hands well and often, particularly before eating and after using the bathroom, and if they work closely with kids (as in a daycare). Avoid close contact with someone who's obviously ill and don't share food, drinks, or eating utensils to also help stop the spread of germs.
In some cases, doctors may give antibiotics to anyone who has been in close contact with a person who has bacterial meningitis to help prevent infection.
When Should I Call the Doctor?
Get medical care right away if you think that your child has meningitis or you see symptoms such as vomiting, headache, lethargy or confusion, neck stiffness, rash, and fever. A baby who has a fever, is irritable, and isn't feeding well also should be seen right away by a doctor.
If your child has been near someone who has meningitis, call your doctor to ask whether preventive medicine is recommended.
