Why is meningococcal harmful?

Meningococcal disease, caused by the Neisseria meningitidis bacteria, is harmful because it can lead to severe health complications such as meningitis and septicemia, both of which can progress rapidly and become life-threatening. It can cause inflammation of the protective membranes covering the brain and spinal cord, leading to symptoms like fever, headache, and stiff neck. Additionally, it can result in long-term complications, including hearing loss and neurological damage. Prompt diagnosis and treatment are crucial to improve outcomes and reduce mortality.
