Meningococcal infections are illnesses caused by bacteria. The most common forms of infections are:
Meningitis. This is infection of the membranes that surround the brain and spinal cord.
Meningococcemia. This is infection of the bloodstream.
Meningococcal infections are not common, but they can be fatal. They occur most often in late winter and early spring. Children are more often affected, but the illnesses also occur in teens and adults. People living in crowded group settings such as school dorms or military barracks are also at risk. There are 2 meningitis vaccines that can help prevent infection.
A case of meningococcal disease needs to be reported to the local public health department. Staff will provide education to you and your family, as well as to the public.
The infections are caused by bacteria called Neisseria meningitidis. The bacteria are spread through close contact with an infected person. A child can inhale droplets in the air from a sneeze or by talking closely with another child. This may cause infection. Most people who get the bacteria and carry them in their nose and throat never get symptoms. In rare cases, the bacteria grow fast, causing serious illness.
Children are more at risk for a meningococcal infection if they have not had a meningococcal vaccine, and have been in contact with an infected person. Other risk factors include:
Low birth weight
Complement deficiency, a disorder of the immune system
Intimate kissing with multiple partners
The most common symptoms of meningitis in children older than 1 year include:
Neck or back pain
Nausea and vomiting
A purple-red, splotchy rash or skin discoloration
In babies, symptoms are not as easy to notice. They may include:
Sleeping all the time
Refusing a bottle
Crying when picked up or being held
Can't be comforted while crying
Bulging soft spot (fontanelle)
Meningococcemia is a life-threatening illness. Symptoms may occur suddenly and get worse quickly. Treatment is needed right away. The most common symptoms include:
Headache, especially when flexing the neck by moving the chin toward the chest
Sensitivity to light
Aching muscles and joints
Not feeling well (malaise)
Feeling tired (lethargy)
Rash. The rash may be small, red, flat or raised spots that turn into larger red or purple patches that may look like bruises.
As the illness gets worse quickly, symptoms may include:
Low blood pressure
Very small amount of urine
The symptoms of meningococcal infections can be like other health conditions. Make sure your child sees a healthcare provider for a diagnosis.
The healthcare provider will ask about your child’s symptoms and health history. Your child will have a physical exam. Your child may also have tests, such as:
Spinal tap (lumbar puncture). A needle is placed into the lower back, into the spinal canal. This is the area around the spinal cord. The healthcare provider removes a small amount of cerebrospinal fluid (CSF) and sends it for testing. CSF is the fluid that bathes your child's brain and spinal cord. The fluid is checked for bacteria.
Blood tests. Blood may be checked for the bacteria. Other blood tests may be done to look for other signs of infection.
Treatment is needed right away. Your child will need to be in a hospital for treatment. Antibiotics are given through an IV. If a child has severe allergies to penicillin, other antibiotics may be used to treat the infection. Antibiotic therapy is done for 5 to 7 days. A child in the hospital will be isolated for 24 hours after antibiotics have been started.
Other treatments are aimed at treating the symptoms. A child with severe infection may need extra (supplemental) oxygen or be put on a ventilator to help with breathing.
Meningococcemia can lead to shock. This is a life-threatening condition. It causes very low blood pressure. Not enough blood flows to organs such as the kidneys, liver, and brain.
The CDC advises that all children 11 to 18 years old have the meningococcal conjugate vaccine (MCV4). The MCV4 is given to children between 11 and 12 years of age, and again at 16 to 18 years of age. If the vaccine was not given at age 11 to 12, it should be given when starting high school, with a booster dose a few years later. High-risk babies and young children can get the vaccine starting at age 2 months. Other high-risk children and teens who need the vaccine include those who:
Have a damaged spleen or no spleen
Are in college and did not have the vaccine in high school
Are military recruits
Are traveling to countries where the infections are common
Are in close contact with people who have meningitis
Have a weak immune system
There is also a meningococcal vaccine that provides protection against serotype B. This is the most common strain known to cause meningococcal meningitis.
Anyone who has been in close contact with an infected child may also need antibiotics. If you have questions, please talk with your child's healthcare provider. The CDC advises the following people be treated if exposed to the bacteria:
Other members of the household, especially young children
Adults and children at child care or nursery school
Anyone who has had contact with the infected child's body fluids through kissing or sharing a toothbrush, cups, or eating utensils
People who sleep in the same area as the infected child
Call the healthcare provider if your child has any symptoms of meningococcal infection. If your child appears seriously ill or is getting ill quickly, get medical help right away.
Report cases of meningococcal disease to your local public health department. Staff will provide education to you and your family, as well as to the public.

Tips to help you get the most from a visit to your child’s healthcare provider:
Know the reason for the visit and what you want to happen.
Before your visit, write down questions you want answered.
At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
Ask if your child’s condition can be treated in other ways.
Know why a test or procedure is recommended and what the results could mean.
Know what to expect if your child does not take the medicine or have the test or procedure.
If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
Know how you can contact your child’s provider after office hours. This is important if your child becomes ill and you have questions or need advice.
