You may have heard this disease referred to as meningococcal meningitis or meningococcemia. Meningococcal disease is a serious and potentially fatal bacterial infection that most often causes severe swelling of the membranes surrounding the brain and spinal cord (meningitis) or a serious blood infection (meningococcemia).1
According to the World Health Organization, meningococcal disease affects about 500,000 people annually. And about 50,000 people die from it every year.2 Even in the United States, there are as many as 1,200 to 3,500 cases of meningococcal disease yearly––the majority of which can be prevented by a vaccination.3,4
