The old saying, "know your enemy," definitely applies in the case of meningococcal disease and meningitis. Some basic knowledge may help protect you and your loved ones from catching the disease. Here are the most important things to know about meningitis:

It’s a potentially fatal, fast-moving disease1,2,7 |

About 3000 Americans get meningococcal disease each year. 11,12 Although this makes it a relatively rare disease, the consequences are severe. As many as 1 in 10 people infected will die from the disease. 2 Up to 1 in 5 of the people who survive will suffer from permanent damage such as hearing loss, brain damage, loss of limbs, severe scarring, and lasting emotional troubles. 2,6,7
Meningitis symptoms can come on very suddenly, and the disease can progress extremely quickly. 2,6,7,8 In some cases, even with treatment, meningococcal disease can kill an otherwise healthy young person in less than 48 hours. 2,6,7,8 When a person has meningitis, they need to be seen by a health-care provider and treated without delay.

It can easily be mistaken for the flu |

Some of the symptoms of meningococcal disease are just like the symptoms of the flu or other common viral illnesses. 2 Both meningococcal disease and other illnesses can cause fever, headache, and nausea. This may lead someone with the disease to just "wait it out."
But a person with meningitis will only get sicker without treatment. 2 That’s why it’s important to watch out for the warning signs.

You can protect yourself and your family from meningitis |

As many as 1 in 3 people may carry the bacteria that causes meningitis without ever getting sick. 14 However, these carriers can give the bacteria to someone else without even knowing it. 2
Even with treatment, not everyone who gets meningococcal disease will survive. That’s why protecting people against the disease is so important. A single vaccination can help.
There are 13 different strains (called serogroups) of meningococcal bacteria. The vaccine that is available right now protects against 4 common strains. In the United States, as many as 83 percent of meningitis cases in adolescents and young adults are caused by these 4 strains and could potentially be prevented by a single vaccination. 3
Of course, no vaccine is guaranteed to protect 100% of the people who receive it. But if you are a parent, ask your child’s doctor about how to protect your child.
