Seek medical attention immediately if you or your child develops symptoms of meningococcal disease. Symptoms of meningococcal disease can first appear as a flu-like illness and rapidly worsen. The two most common types of meningococcal infections are meningitis and septicemia. Both of these types of infections are very serious and can be deadly in a matter of hours.
And though the symptoms are often caused by the flu, they could also be the sign of something much more serious: meningitis. About to 1, Americans contract meningitis each year — a number that's become much lower since more and more people are getting the vaccine. However, 10 to 15 percent of these people die, while about 20 percent are left with permanent disabilities, according to the National Meningitis Association. The two most common types of meningitis are viral and bacterial meningitis.
Viral meningitis is the most common type of meningitis, an inflammation of the lining of the brain and spinal cord. It is often less severe than bacterial meningitis, and most people get better on their own without treatment. However, anyone with symptoms of meningitis should see a doctor right away because some types of meningitis can be very serious.
