A30-A49: Other bacterial diseases
A39: Meningococcal infection
Meningococcal infections are a group of illnesses caused by a bacterium called Neisseria meningitidis. These infections can lead to serious conditions like meningitis, an infection of the lining of the brain and spinal cord, and septicemia, a severe blood infection. Meningococcal bacteria are spread through close contact with an infected person, such as coughing, sneezing, or kissing. Initial symptoms may include fever, headache, stiff neck, nausea, and tiredness, which can progress to confusion, seizures, and even coma in severe cases. These infections primarily affect the nervous and circulatory systems. It's crucial to receive early diagnosis and treatment as these conditions can rapidly worsen and become life-threatening. Meningococcal infections can occur at any age, but they are most common in infants, teenagers, and young adults.
