1. Reason

This is spread by bodily secretions or droplets with the virus hidden in the meatus nasopharyngeus of patients or healthy people.

2. Symptom

The virus causes meningitis, sepsis, and other diseases.
The meningococcal meningitis starts with headaches, fever and nausea, and when further progresses, the symptoms lead to a semiconscious condition. The meningococcal sepsis is a condition where meningococcus is found in the blood without any symptoms of meningitis, leading to bleeding on the skin and death within 24 hours.
Other infections include pneumonia, arthritis, epiglottiditis, tympanitis, and pericarditis, but meningococcus was found in the samples of the area without any characteristic symptoms of meningococcal infections.

3. Preventive Method

Vaccination can prevent the meningoencephalitis. The most common side effects after vaccination are redness, edema, pain, mild fever, torpor and very rarely, anaphylaxis and Gilang-Barre syndrome after vaccinated with protein-bound vaccines.

4. Vaccination Guide

Vaccination against meningococcus is not a national vaccination program.
Since the meningococcal vaccination is recommended for those who are at high risk of infection, consultation with a doctor is required before deciding whether to vaccinate.
