“Any type of infection caused by the Neisseria meningitidis bacteria is known as meningococcal disease. The two most common types are meningococcal meningitis and meningococcal septicemia (a blood infection).

Meningococcal disease has become less common in the U.S. than it once was. However, in 2024, there was a resurgence with 503 cases reported. But it can be fatal or cause great harm without prompt treatment. According to the CDC, even with antibiotics, 10%-15% of those infected will die, and about 1 in 5 of those who survive are left with long-term disabilities that include deafness, brain damage, neurological problems, and loss of a limb.”
