Meningococcal prophylaxis refers to the preventive measures taken to reduce the risk of contracting meningococcal disease, which is caused by infection with the bacterium Neisseria meningitidis.
Meningococcal disease can present as meningitis, an inflammation of the protective membranes surrounding the brain and spinal cord, or as septicemia, a severe bloodstream infection. It is a potentially life-threatening condition, particularly in infants, young children, and adolescents.
Meningococcal prophylaxis primarily involves the administration of antibiotics to individuals who have been in close contact with a person diagnosed with meningococcal disease. This helps to eliminate or reduce the carriage of the bacteria in the throat and prevent the spread of infection to others.
Other preventive measures may include vaccination with meningococcal vaccines, especially for individuals at higher risk of infection or during outbreaks. These vaccines provide protection against several serogroups of N. meningitidis.
It is important to promptly seek medical attention if someone exhibits symptoms of meningococcal disease, such as fever, headache, stiff neck, rash, vomiting, and sensitivity to light. Early diagnosis and treatment are crucial for the management of the disease.

Causes of Meningococcal Prophylaxis
- Infection with Neisseria meningitidis bacteria
- Exposure to respiratory droplets of an infected person
- Close contact with an infected person, such as living in the same household or sharing items like utensils or cigarettes
- Being in crowded or close settings, such as schools, college dormitories, military barracks, or prisons
- Having a weakened immune system, which can make individuals more susceptible to infections
- Living or traveling to areas with high rates of meningococcal disease outbreaks
- Participating in activities that increase the risk of transmission, such as attending festivals or large gatherings
- Stiff neck
- Nausea or vomiting
- Sensitivity to light
- Confusion or disorientation
- Rash or purple patches on skin
- Joint or muscle pain
- Difficulty walking or standing
