Neisseria meningitidis are spread from person to person through the exchange of respiratory and throat secretions during close or lengthy contact, especially if living in the same household. The bacteria are not spread by casual contact or by simply breathing the air where a person with meningococcal disease has been.
If a person gets meningococcal meningitis, the protective membranes covering their brain and spinal cord, known as the meninges, become infected and swell. This is characterized by a sudden onset of fever, headache, and stiff neck. It is often accompanied by other symptoms, such as Nausea Vomiting Photophobia (sensitivity to light) Altered mental status (confusion).
Early diagnosis and treatment are very important. If symptoms occur, the patient should see a doctor immediately. Meningococcal meningitis can be treated with a number of effective antibiotics. Antibiotic treatment should reduce the risk of dying, but sometimes the infection has caused too much damage to the body for antibiotics to prevent death or serious long-term problems.
Major research on disease:
The Health Burden of Invasive Meningococcal Disease is a Systematic Review.Meningococcus bacteria are spread through the exchange of respiratory and throat secretions like spit (e.g., by living in close quarters, kissing). Meningococcal disease can be treated with antibiotics, but quick medical attention is extremely important.
